  1. Earlier today, the first third-party benchmarks of the upcoming AMD Radeon RX 7900 XTX leaked out. And much to the surprise and shock of many, the GPU was seen really struggling against Nvidia GeForce RTX 4090 as well as its direct competitor, the RTX 4080. This was quite contrary to what AMD had shown during its presentation. However, scores for new benchmark runs have leaked since then, and it looks like the first set of results that leaked earlier today were severely underselling the actual performance the new AMD GPUs have to offer. In the new OpenCL run, the AMD RX 7900 XTX has put up 228,647 points, which is 52% higher than that in the earlier result. In this instance, the RTX 4080 is seen to be around 10 to 17.6% faster than the RTX 4080. Meanwhile, in the Vulkan API test, the RX 7900 XTX is quite a distance ahead as it is nearly 21% faster than the RTX 4080. Compared to the previous result, the new score is 96% higher, as the XTX has put up 179,579 points. These new results are much more in line with what we had estimated using AMD's own benchmark numbers. In brief, the raster output of the 7900 XTX fell in between the 4080 and 4090, although in ray tracing, it was behind both the RTX 40-series GPUs.

  2. On November 3rd, AMD announced its RDNA 3-based RX 7900 series cards based on the Navi 31 die. The duo of cards in the form of the RX 7900 XTX and the 7900 XT come in at $999 and $100 less, respectively, to take on Nvidia's $1,199 RTX 4080 16GB model which is now simply called RTX 4080 as Nvidia killed or rather "unlaunched" the 12GB variant. The lesser 4080 is allegedly becoming the RTX 4070 according to tipsters. Since then, AMD shared some more performance details on its RX 7900 series including benchmarks for the 7900 XT, and more digs at Nvidia. Using that data, we approximated the performance level of the upcoming Radeon RX 7000 and compared it against RTX 4080 and 4090. In a nutshell, the estimated performance was exactly where you'd expect as the raster output of the 7900 XTX fell in between the 4080 and 4090, while in ray tracing, it was behind both the RTX 40-series GPUs. These cards are due to be released in a week's time and today, we have the first leaked synthetic benchmark scores of the RX 7900 XTX. However, AMD fans will certainly be very disappointed as the 7900 XTX has seemingly put up very poor results. The leaked results come in the form of Geekbench results where Nvidia's RTX 4090 is a massive 143.6% ahead in the OpenCL compute test. Meanwhile, the main competitor of the 7900 XTX, the RTX 4080 is 65.5% ahead. The AMD GPU has managed 150,372 points. As you can see in the images below, the test systems are very similar, almost identical, and both the systems were running a Ryzen 9 7950X CPU. The Vulkan score of the RX 7900 XTX is also nothing to write home about. The XTX has put up 91,652 points, which is behind the RTX 3090 Ti, 3090, and also AMD's own RX 6900 XT and 6800 XT from the previous generation. Of course, these are pre-release numbers so they may not mean much and the launch day results could be completely different. However, the data is scary, especially if you are an AMD fan or want competition in the GPU market. Let us hope the sample(s) tested here are just faulty engineering samples or the drivers are botched and the upcoming RX 7900 XTX and 7900 XT are actually impressive.

  3. AMD launched its Radeon RX 7000 series graphics cards, based on the new RDNA 3 micro-architecture last month. While the company was pretty tight-lipped about the performance of its new 7900 series GPUs on that day, Team Red did share more details on the expected performance, though no comparisons against Nvidia's RTX 4090 or previous gen 3000 series were made. Using the numbers provided by AMD, we estimated the expected performance of the flagship $999 RX 7900 XTX as well as the $899 RX 7900 XT. The estimated performance is pretty much in line with what one would have guessed from judging by the last gen, ie, the rasterization throughput is better than the RTX 4080 but it cannot compete in terms of ray tracing. The $1,599 RTX 4090, though, remains untouched as neither the 7900 XT nor the 7900 XTX is anywhere close. Aside from these two, AMD is also supposedly going to launch the RX 7800 series next year. While the 7900 series is based on Navi 31, the RX 7800 series, which is a tier-below product, is expected to be based on the Navi 32 instead. And like early reports had suggested, we now know that the Navi 32 consists of 30 Work Group Processors (WGPs) or 60 Compute Units. That's because AMD's ROCmWMMA GitHub repository posted the following information recently which confirms the CU counts of the Navi 3x hardware. 60 CU RX 7800 XT or RX 7800? While we have the overall specifications of the Navi 3x now, it is hard to say right now what the exact specifications of the RX 7800 series will be. However, if the RX 7800 XT is indeed a 60CU SKUthen, depending on how AMD prices that SKU, it will likely be seen as a failure as the 6800 XT had 12 more compute units at 72. This means the performance uplift gen-on-gen will be extremely poor if not non-existent for the 7800 XT. Another possibility is that the full Navi 32 60 CU die actually becomes the RX 7800 non-XT. This will make much more sense as an upgrade over the RX 6800. If the latter is the case then AMD will cut the Navi 31 further down beyond 84 CUs that we have on the 7900 XT. However, early rumors do not indicate of such any such chip existing which means AMD may not have any RX 7800 XT in the works at all. So users who have a 6800 XT now will have to move up a tier to the RX 7900 series, which is priced significantly higher than what the 6800 XT or even the 6900 XT are currently selling for.

  4. If rumors are to be believed, AMD might release non-X Ryzen 7600, 7700 & 7900 processors in the first quarter of next year. In August this year, AMD announced its Zen 4 based Ryzen 7000 series processors. These processors have provided great performance increase over the previous Zen 3 based Ryzen 5000 processors. This despite the fact that the new Intel Raptor Lake processors have been defeating them comfortably in gaming benchmarks. Another problem these new AMD Ryzen 7000 series processors are facing is the overall cost of buying the platform. The new motherboards required for Ryzen 7000 processors are quite expensive. This is unlike both previous gen AMD motherboards and also its competitor Intel CPU’s motherboards, which are significantly cheaper than the Ryzen 7000 motherboards. The reason is simple. AMD went futuristic with their aims. The Ryzen 7000 series works with only DDR5 RAM, supports PCIe 5.0 and also requires an entirely new CPU socket. All this adds to the overall motherboard cost. This is why these new processors from AMD, in-spite of being good, are not that attractive to the buyers. Looks like AMD wants to do something to change that. New Non-X Ryzen Processors Coming When AMD released the Ryzen 7000 processors, it released just 4 processors in the line-up. AMD Ryzen 7950X, 7900X, 7700X, 7600X. If rumors are to be believed, AMD might add more processors to the line-up. Specifically non-X processors. Twitter based leaker chi11eddog (@g01d3nm4ng0) is claiming that AMD is planning to release three new non-X processors. Specifically AMD Ryzen 7600, 7700 & 7900. All these processors are claimed to be releasing in the first quarter of next year, 2023. As per the claims, the AMD Ryzen 7900 based CPU will have a max speed (boost clock) of 5.4 GHz, which is 200MHz slower than Ryzen 7900X. It is expected to cost $429, a whole $120 cheaper than the 7900X, which released with a MSRP of $549. The AMD Ryzen 7700 will have a max speed of 5.3GHz, which is 100MHz slower than 7700X. It’s said to cost $329, which is $70 cheaper than the 7700X, which came with an original MSRP of $399. The third on the list is the cheaper AMD Ryzen 7600 with a max speed of 5.1GHz, which is 200MHz slower than the 7600X. It’s claimed to cost $229, which again is $70 cheaper than 7600X, which came with an original MSRP of $299. All of them, however, the leaker claims, will come with a TDP of just 65W. Which is a puts a massive limit in their power consumption. While the Ryzen 7600X and 7700X come with a TDP of 105W, the 7900X has a TDP of 170W. Now for all of that to change to just 65W raises many questions, both about AMD’s plans and also leaker’s claims. Conclusion AMD Ryzen 7000 series processors are not selling as they should and so big is the problem that AMD is massively cutting their production. So the new cheaper processors are much welcome if they come out to be true. It will make the Ryzen platform cheaper and more attractive. However, the limited TDP can be a big concern. While it’s true higher power does not always provide a huge uplift in performance, such a hard limit on the base power of Ryzen 7900 can be an issue. However, PC manufacturer only Ryzen 5900 CPU did have such limit, but as these processors are not available to common consumers directly, so we cannot say for sure. Nor can we say whether these new processors are being made for the public or will be made available only to the PC manufacturers. Another possibility is AMD releasing a cheaper motherboard chipset to power these processors. Namely, the A620 chipset, which does not have any release date or any specifications yet. Nor AMD seems to have spoken anything about it. Up-till now, we only know about the X670E, X670, B650E, B650 chipsets and none of the motherboards using these chipsets are really cheap. Whatever it can be. These rumors do give us a fair bit of an idea of what AMD is considering to do. These specs, however, are never final and could always change as AMD engineers experiment with the speed and power requirements and then AMD considers the market position in order to price them competitively. What we can do is to wait and see what AMD does. AMD Might Release Non-X Ryzen 7600, 7700 & 7900 CPUs in Q123
  5. At the beginning of this month, AMD unveiled its all-new RX 7000 series desktop graphics cards based on the RDNA 3 architecture. The company launched two AMD cards, namely the RX 7900 XTX and the RX 7900 XT. While some performance idea regarding the flagship RX 7900 XTX was provided, AMD shared no details in this aspect about the RX 7900 XT. Today, right before the RTX 4080 comes out on the 16th, AMD has decided to share more details on its RX 7900 series, including performance numbers for the 7900 XT. Also, information on stuff like the cooler design, PCB design, and more, has also been provided. You can check them out in the images below (click to enlarge): And just like on its 3rd November event, there are several digs and shots at Nvidia this time around too. AMD makes sure you know that its new cheaper cards are a simple plug-and-play solution compared to Nvidia's more expensive RTX 4080 priced at $1,199. This is because the new 7000 series cards continue to use the traditional 8-pin power connectors and the size of the cards is in the same ballpark as existing high-end GPUs. There are more comparisons against the RTX 40-series counterpart where AMD clearly highlights its advantages in terms of display output (Display 2.1 vs 1.4a), and additional VRAM amount, even on the much cheaper $899 RX 7900 XT. AMD also compares the core specs of the RX 7900 directly with the 4080 which does not make any sense as the architectures are vastly different. However, once again, any performance comparisons between its own cards and the RTX 4080 were missing as the 4080 is not out yet. AMD did not compare its RX 7900 series to Nvidia's flagship, the $1,599 RTX 4090 and it is because the new RDNA 3 cards probably come nowhere close to the 4090 in terms of ray tracing performance at least. And raster performance will also likely be a fair way behind. Speaking of performance, additional performance details have been provided today over what we previously had. First up, we have the rasterization data of the RX 7900 series at 4K and 8K. This time, as mentioned above, we have the numbers for the RX 7900 XT as well. Ironically, AMD calls its 8K gaming slide "True 8K gaming" and yet it uses FSR upscaling to achieve 60+fps results. Finally, we have the benchmark data that will likely disappoint many people as it shows the ray tracing performance, something which was rather lackluster in RDNA 2 compared to Nvidia's Ampere (RTX 3000 series) cards. While it looks like decent progress has been made on the RX 7000 series compared to the last gen, the ray tracing numbers are still nowhere close to Nvidia's RTX 4090, although to be fair to AMD, it only compares the 7900 series to the 4080 only. In Dying Light 2, which looks like the best result for RDNA 3, the 7900 XTX manages a 2x 1x or 100% improvement in performance compared to the RX 6950 XT. In the rest of the titles, the improvement varies between 44% and 65%. Via: Tom's Hardware AMD finally shares performance numbers on the RX 7900 XT, takes more digs at Nvidia
  6. Last night was the second Tuesday of the month, which meant it was Patch Tuesday time. As such, Microsoft released the security update for Windows 11, Windows 10, as well as for Windows 8.1, and Windows 7. Among others, the latest November Patch Tuesday fixes a Spectre Variant 2 like AMD CPU vulnerability tracked under ID "CVE-2022-23824" which affects almost all AMD Ryzen, EPYC, and Athlon desktop, notebook and server processor SKUs. The latest Zen 4-based Ryzen 7000 chips however are not affected. In an advisory published earlier today, AMD has described the new security flaw: AMD is aware of a potential vulnerability affecting AMD CPUs where the OS relies on IBPB to flush the return address predictor. This may allow for CVE-2017-5715 (previously known as Spectre Variant 2) attacks based on RET predictions in cases where the OS relies on IBPB without the use of additional software mitigations, to flush the return address predictor. CVE-2022-23824 IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. Hence, users running an AMD system, barring the latest Ryzen 7000 chips, are advised to update their Windows PCs. You can either use Windows Update in Settings to automatically download the update or manually grab the standalone updates from the Microsoft Update Catalog website. Find the links in the articles below: Windows 11 Windows 10 Windows 8.1/7 Here are all the AMD CPU families affected: Desktop AMD Athlon™ X4 processor AMD Ryzen™ Threadripper™ PRO processor 2nd Gen AMD Ryzen™ Threadripper™ processors 3rd Gen AMD Ryzen™ Threadripper™ processors 7th Generation AMD A-Series APUs AMD Ryzen™ 2000 Series Desktop processors AMD Ryzen™ 3000 Series Desktop processors AMD Ryzen™ 4000 Series Desktop processors with Radeon™ graphics Mobile AMD Ryzen™ 2000 Series Mobile processor AMD Athlon™ 3000 Series Mobile processors with Radeon™ graphics AMD Ryzen™ 3000 Series Mobile processors or 2nd Gen AMD Ryzen™ Mobile processors with Radeon™ graphics AMD Ryzen™ 4000 Series Mobile processors with Radeon™ graphics AMD Ryzen™ 5000 Series Mobile processors with Radeon™ graphics Chromebook AMD Athlon™ Mobile processors with Radeon™ graphics Server 1st Gen AMD EPYC™ processors 2nd Gen AMD EPYC™ processors 3rd Gen AMD EPYC™ processors Alongside the CPU vulnerability, AMD has also shared details about several security flaws affecting its graphics too. The company released graphics drivers and AGESA updates to fix the issue in its GPUs and integrated graphics, respectively. In case of the Radeon RX 5000 and RX 6000 series GPUs, the issue is patched with the Radeon 22.5.2 driver. If you are already on a newer driver, you need not have to worry. For PRO series cards, you can grab the AMD Software: PRO Edition 22.Q2 or any newer driver. For AGESA firmware updates, you can head over to AMD's official website to find more details. Latest Patch Tuesday mends Spectre V2 vulnerability affecting AMD Ryzen Windows PCs
  7. With the RDNA 3 based AMD Radeon RX 7000 series graphics cards, AMD has re-entered the graphics card race against Nvidia GeForce RTX 4000 series. On Friday, AMD announced its newest generation of graphics cards. The RDNA 3 based AMD Radeon 7000 series cards were announced via its live-streaming conference. RDNA 3 In it, AMD first talked about it’s Ryzen 7000 CPUs. It also talked about the ecosystem AMD has created with all the other products like gaming consoles using AMD processors. After a lot of self-praise, AMD finally revealed the RDNA 3 graphics cards architecture. AMD said that power and efficiency is its priority when designing the RDNA 3. With an aim of being a leader in performance-per-watt. With RDNA 3 AMD claims it wants to bring CPUs, GPUs and softwares to come together. Chiplet Design For Graphics Cards AMD Radeon RX 7000 RDNA 3 Chiplet Design. Credit: AMD. AMD announced that the RDNA 3 will be based on a chiplet design and will be the world’s first chiplet based gaming GPU. With it, AMD claimed that it allows them to use a modular approach and optimize the performance efficiency. They said that, just like on the Ryzen CPUs, chiplet design allows them to mix and match the technology for each function. AMD Radeon RX 7000 RDNA 3 GCD MCD. Credit: AMD. In it, AMD has divided the GPU into two main parts. The GCD, which is the main processor based on the 5nm technology in a 306mm2 size and 96 compute units in the GPU. This includes the shaders, the display engine and a newly made media engine too. The second part is the MCD, which is for the cache and is based on the 6nm technology. It’s for the memory sub-system, featuring GDDR6 controllers and up-to 96 MB of Infinity Cache. Basically, the MCD will be 37.5mm2 in size and will come with 6 chiplets in the flagship graphics card. AMD Radeon RX 7000 RDNA 3 GPU Power. Credit: AMD. RDNA 3 Performance All this, AMD claims, gives them a powerful graphics capability. With 61 TFLOPS of compute, compared to 23 TFLOPS in RDNA 2. World’s fastest chiplet interconnect with 5.3 TB/s of peak bandwidth. Allowing full potential of 24 GB of GDDR6 memory. When all put together, AMD said it gives a total of 58 billion transistors in this design. Giving what AMD claims an incredible amount of gaming performance. AMD said that it is going to use two different clocks in the RDNA 3 architecture for better optimized performance. The shader clock will run at 2.3 GHz, allowing 25% power savings. The powerful gaming clock will run at 2.5 GHz at 15% higher frequency than RDNA 2 at launch. AMD Radeon RX 7000 RDNA 3 Chiplet GPU Shot. The middle part is the main processor and the 6 smaller chiplets are the cache. Credit: ASCII KADOKAWA. AMD claims that RDNA 3 has 54% improvement over the RDNA 2 architecture in performance-per-watt. AMD also claims that the new MCD cache, with it’s 5.3 TB/s of peak bandwidth, is 2.7x faster than the RDNA 2 architecture. It’s based on the 2nd gen Infinity Cache. It also claims that each of the 6 chiplets are connected to the 64-bits of GDDR6 memory, which combined makes up to 384-bit memory width. New RDNA 3 Unified Compute Unit AMD Radeon RX 7000 RDNA 3 Unified Compute Units AMD also detailed the new RDNA 3 based gaming oriented Unified Compute Units. With an insistence on the word unified. It’s an integrated unit with shared resources. It has highly efficient stream processing, additional AI acceleration capabilities and enhanced ray-tracing acceleration. Thanks to the 5nm tech, AMD claims to be able to pack 54% more transistors in a less area, increasing the transistor density by 165%. AMD also detailed the new Stream Processors. It uses a new dual issue wave 32 units. Allowing two different instructions in the 32 lane or use them in parallel like in RDNA 2. Allowing two different operations or mixing and matching workloads. All resulting in faster frame render times for higher FPS and better utilization of all the functions in the compute unit. Allowing it to handle 2x the instructions per clock. Then AMD talked about the new RDNA AI acceleration. With the AI accelerators being 2 per compute unit, allowing up-to 2.7x performance. AMD also showed its 2nd gen ray-tracing accelerator, built on new instructions in the shader and with a support for many features. All of it combined, AMD claims that it has 50% more performance per compute unit in ray-tracing. New Display Engine AMD Radiance Display Engine. Credit: AMD. AMD announced a new Radiance Display Engine. It features the industry’s first DisplayPort 2.1 support for a high performance gaming graphics card. DisplayPort 2.1 supports 480Hz of refresh rates at 4K resolution and up to 165Hz at 8K. This new display engine supports 12 bit-per-channel color, allowing up to a massive amount of 68 billion colors. The display link bandwidth is increased up to 64 Gbps which is a double than that of RDNA 2 and gives higher refresh rates at higher resolutions. It’s important to mention that Nvidia GeForce RTX 40 does not come with the DisplayPort 2.1 or even 2.0 support. New Dual Media Engine AMD Dual Media Engine. Credit: AMD. AMD has also announced a new Dual Media Engine. The new media engine supports 2 simultaneous encode and decode together up to 8K60 for AVC (H.264) and HEVC (H.265). It also supports the latest gen hardware AV1 encoding and decoding. The new media engine also comes with an enhance AI support for video encoding. The new media engine comes with a 1.8x improvement in the performance when compared to RDNA2. RX 7900 XTX and 7900 XT Announced AMD Radeon 7900 XTX and AMD Radeon 7900 XT. Credit: AMD. After all the details about the RDNA 3 architecture, AMD finally revealed the details of the graphics cards in the RX 7000 series. The AMD Radeon RX 7900 XTX with 24GB of GDDR6 and the AMD Radeon RX 7900 XT with 20GB of memory. AMD Radeon RX 7900 Series Product Specifications. Credit: AMD. AMD Radeon RX 7900 XTX AMD Radeon 7900 XTX Stats. Credit: AMD. AMD claims that the RX 7900 XTX is up to 1.7x faster than AMD Radeon RX 6950 XT graphics card at native 4K. It also claims that it has 1.6x more performance in ray-tracing in the same. The AMD Radeon RX 7900 XTX features 96 RDNA 3 based Unified Compute Units and runs at 2.3 GHz game clock. It comes with 24 GB of GDDR6 with 384-bit support. The Radeon RX 7900 XTX comes with AV1 encode and decode for streaming and video export. It also has the latest DisplayPort 2.1 technology for up to 4K 480 FPS or 8K 165 FPS. The total board power, AMD claims, is just 355W. A reminder, Nvidia claims that it’s latest-gen flagship GeForce RTX 4090 requires 450W. So AMD’s Radeon RX 7900 XTX requiring just 355W is very much welcome. AMD Radeon RX 7900 XT AMD Radeon 7900 XT Stats. Credit: AMD. AMD also announced Radeon RX 7900 XT which it claims comes with a massive leap in performance over the previous generation. It features 84 Unified Compute Units running at a game clock of 2 GHz. The RX 7900 XT comes with 20 GB of GDDR6 memory at 320-bit. It also comes with the same type of support for AV1 and DisplayPort 2.1. The RX 7900 XT requires just 300W of total board power. Two 8-pin PCIe Power Connectors And Nvidia AMD Radeon 7900 XTX Size, Slot Size And Power Pin’s Compared to RX 6950 XT. Credit: AMD. To rub it in into Nvidia, AMD announced that these new cards do not require one to rebuilt their PCs. Nor there is any need for any new power adapter. It’s because these cards will not be using the new 16-pin power adapter, which Nvidia is using in its RTX 4090 cards. To those who are unaware, the internet is filled with reports of these new 16-pin power adapters melting and potentially even damaging the RTX 4090 cards. Instead, RX 7900 XTX will require 2 8-pin PCIe GPU power cables, which is a standard now. Custom graphics card manufacturers might add one more 8-pin requirement though, to allow for more overclocking. In addition to above, AMD detailed how their new graphics cards come with DisplayPort 2.1 and the latest generation of graphics cards from their rival (Nvidia) come with just DisplayPort 1.4 support. AMD says that a lot of display manufacturers, including Dell, Samsung, ASUS, LG and Acer are going to launch displays with DisplayPort 2.1 support starting next year. AMD also announced new FSR 2.2 which is an improvement over FSR 2. Performance AMD Radeon 7900 XTX Gaming Performance. Credit: AMD. AMD claims that with RX 7900 XTX, one will be able to game at 1440P at high refresh rates. With the likes of Apex Legends reaching 300 FPS, Overwatch 2 reaching 600 FPS and Valorant reaching 833 FPS. In 4K gaming, these new cards do even better. AMD claims that at max settings with FSR up-scaling enabled, many AAA games reach 350 FPS. With some multiplayer games even reaching 700 FPS. AMD also showcased a game running at 96 FPS at 8K resolution with FSR enabled. It also claimed that in Ray-Tracing at 4K, many games are able to run above 60 FPS with FSR enabled. AMD then announced its partnership with many game developers, including Ubisoft and Epic and claimed optimized performance for the Radeon graphics cards in their gaming engines and upcoming games. FSR 3 Announced AMD FSR 3. Credit: AMD. AMD in its announcement also announced a new version of it’s up-scaling tech FSR. Namely, FSR 3. It seems to be directly rivaling Nvidia’s DLSS 3. Those unaware, DLSS 3 is accused of inserting fake frames into the games to make it look smooth but in real the outcome is not so smooth performance increase. FSR 3, AMD claims, uses new fluid motion technology. Coming in 2023, AMD claims it will provide 2x more FPS over FSR 2. Software, Streaming and Solutions AMD dedicated the third part of it’s conference to three different things. Software, Streaming and Solutions. They detailed the AMD Adrenalin Software for AMD graphics cards which offers state-of-the-art features and next level gaming experiences, streaming and creation. To put the point forward, AMD showed how AMD Adrenalin Software offers so many features in one unified UI, without any registration or log-ins required and it does not track the users either. This is a direct targeting of Nvidia GeForce Experience, which does have these problems. In new features, AMD announced a new Hypr-RX mode in the AMD Adrenalin Software. Hypr-RX combines all the performance boosting technologies of the Adrenalin all at the same time to boost the gaming performance in a one-click experience to improve the frame rate and latency. It showed how a game, with Hypr-RX, saw the FPS increase from 90 FPS to 166 FPS and latency decrease from 30 ms to 11 ms. The new Hypr-RX tech is going to come out early next year.

The Radeon RX 7900 XTX will cost $999 and the Radeon RX 7900 XT will cost $899. Which is far, far cheaper than Nvidia’s current flagship offering. The RX 7900 XTX and 7900 XT will release on December 13 this year. Conclusion AMD Radeon 7900 Animated Screenshot. Credit: AMD. There are many important points we would like to make. Besides all the marketing taglines, AMD seems to have done quite a good work. Especially when it comes to pricing and power usage. This card is most likely going to rival Nvidia GeForce RTX 4080 graphics cards, not RTX 4090. Some Twitter users like @harukaze5719 even made a graph showing how it might perform compared to Nvidia GeForce RTX 4090 and results look promising. Another famous Twitter user @Kepler_L2 is disappointed by its Ray-Tracing performance though. Honestly, many of us don’t care about the Ray-Tracing performance as long as the main performance is good enough. The chiplet design is quite an interesting move by AMD. We will have to see how much improvement or a problem it can be. Simply put, chiplets are easy to manufacture when compared to massive single processors. However, they have various problems associated with them, like performance issues between chiplets and latency between them. However, going forward we might see all processor manufacturers, whether it’s CPU or GPU, to adapt this technology. Meanwhile, TechPowerUp is reporting that ASUS has already announced its own RX 7900 series cards with 3 8-ping power plugs. Coming back to performance. It’s never wise to believe what the company says. They might say anything they want. A lot of the performance stats mentioned in the conference are with the FSR enabled, which does not show true performance numbers. It’s only when the reviews and benchmark arrive that we might understand how things stand, whether AMD can take on Nvidia properly. Till then, we will remain quite excited about it. RX 7900 XTX, 7900 XT GPUs & Everything Else Announced By AMD
  8. AMD is launching the RX 7000 series graphics cards today based on the RDNA 3 architecture (codenamed Navi 3x). As of today, AMD has only announced its Navi 31-based RX 7900 XTX and RX 7900 XT. The full specs of the two cards are detailed below. RX 7900 XTX The flagship RX 7900 XTX is packing 48 WGP (Work Group Processor) or 96 Compute Units (CU) for a total of 6,144 Stream Processors (SP). The Game Clock, which is the typical average clock speed of the GPU, is 2.3GHz. It has 24GB of 20Gbps GDDR6 memory across a 384-bit wide memory bus for a bandwidth of 960GB/s.The power consumption of the 7900 XTX is rated for 355W. With all this power, AMD claims the 7900 XTX is up tp 70% faster than the RX 6950 XT at 4K. The card is priced at $999. RX 7900 XT Meanwhile, the slightly cut-down RX 7900 XT features 42WGP or 84CU for a total of 5,376 SP. The 7900 XT has a game clock 2GHz. The memory subsystem is also slashed down to 20GB across a 320-bit bus. The bandwidth is 800GB/s (for 20Gbps). The infinity cache will also be decreased from 96MB down to 80MB. The power draw of the card is 300W. The card is priced at $899. Both the RX 7900 XTX and the RX 7900 XT will be available right before Christmas on December 13. AMD's new RDNA 3 RX 7900 XTX, 7900 XT look like true Nvidia RTX 4090, 4080 killers
  9. The alleged die shot of the GPU powering AMD's upcoming RX 7000 series graphics cards, based on the RDNA 3 architecture, which are launching later tonight, has leaked. While it is in no way a perfectly clear capture in glorious 4K or something, we do get a fair idea of what the Navi 31 die itself looks like. First, do not be confused by that "A" shaped logo on top of the image. That is the watermark of Angstronomics, who is the blogger that leaked this photo. What's actually interesting about the die shot is the layout of the chip and its infinity cache components. We know that AMD is moving to a chiplet-based packaging on its GPUs too. While the core will be based on an alleged 308mm2 GCD (5nm), the infinity will consist of six MCDs (6nm) each being 37.5mm2. Although prior rumors had suggested that each MCD will have 64MB of stacked cache, more recent reports suggest 16MB on each MCD for first-gen Navi 31 for a total of 96MB infinity cache. There is reportedly also the possibility of 32MB MCDs or a total of 192MB of infinity cache on Navi 31. However, that is apparently planned for when the Navi 31 refresh RX 7x50 series comes out sometime in the future. Tonight, AMD is expected to unveil two premium SKUs, the RX 7900 XTX and the RX 7900 XT. The chiplet design approach allows AMD to utilize a lower-cost process for stuff like the I/O or memory whereas the cutting-edge lithography can be used for the core itself. RX 7900 XTX The flagship RX 7900 XTX is rumored to pack 48 WGP (Work Group Processor) or 96 Compute Units (CU) for a total of 12,288 Stream Processors (SP). It will purportedly have 24GB of 20Gbps GDDR6 memory across a 384-bit wide memory bus for a bandwidth of 960GB/s. This is still not fully confirmed though and AMD may even use the slightly slower but more abundant 18Gbps memory (864GB/s bandwidth) that it is currently deploying on its RX 6x50 refresh SKUs like the RX 6950 XT, 6750XT, and 6650 XT. RX 7900 XT Meanwhile, the slightly cut-down RX 7900 XT will purportedly feature 42WGP or 84CU for a total of 10,752 SP. The memory subsystem is also slashed down to 20GB across a 320-bit bus. And once again, depending on the speed of the memory chips used, the bandwidth could be 800GB/s (for 20Gbps) or 720GB/s (for 18Gbps). The infinity cache will also be decreased from 96MB down to 80MB. RX 7800 XT Finally, we have the RX 7800 XT which will reportedly have 30WGP or 60CU which means 7,680 SP in total. This will be based on Navi 32 die instead of Navi 31. In terms of memory, the 7800 XT is expected to have 16GB of 20Gbps or 18Gbps GDDR6 for a total bandwidth of 640GB/s or 576GB/s respectively. Coming to the infinity cache, the 7800 XT will allegedly come with 64MB of the on-die cache. Expect to know more later tonight when AMD officially takes the wraps off RDNA 3.

  10. AMD recently published an official statement regarding its findings on Windows 11 performance loss when paired with Ryzen 7000 series CPUs. The company claimed in its statement that it did not encounter too much variance in performance when it compared the output across Windows 11 and Windows 10. AMD instead put the blame for differences on other factors that weren't quite in its control. The company was responding to reports from reviewers and users who had noted performance discrepancies on the latest gen Ryzen 7000 series CPUs. The big differentials were noted especially were fewer Zen 4 cores, via CCD disablement, were being deployed. One of the testers, CapFrameX, who had put out the original performance reports retested Windows 11 22H2 to see if AMD's claim was accurate. Two games - Cyberpunk 2077 (CB 2077) and Shadow of the Tomb Raider (SotTR) - were tested. This time, instead of a Ryzen 7000 chip, a Zen 3-based Ryzen 5900X was used. The data suggests there is certainly a lowered performance trend that goes away with a fresh reinstallation of the OS. In CB 2077, there is close to a 15.5% bump up in the average framerate. Meanwhile, in SotTR, the gap is even bigger with close to a 20% uplift. This suggests some hiccups are present, perhaps on Windows 11 22H2 itself, or else a clean installation should not cause such a large variation. To be fair to AMD though, the company's knowledge base (KB) document only mentions Ryzen 7000 series CPUs which means it's possible it is yet to test previous-gen parts. Regardless, AMD isn't the first company to be facing issues since the Windows 11 2022 feature update. Nvidia too has had quite a few performance and other bugs on it. For example, with its latest drivers, the company confirmed a Task Manager mis-reading issue, and this was after the bugs were supposed to have been fixed. Source and image: CapFrameX (Twitter) Despite AMD's denial, data suggests Windows 11 22H2 performance loss on Ryzen is real
  11. It’s a tough time to be in the PC industry, but at least the consoles are doing alright AMD was riding high last year as consumers bought computers in droves and cryptocurrency miners snapped up every GPU they could get, but this year, the company has come crashing down to the ground. While it’s bringing in more money than it was before, thanks in part to better sales in the data center and gaming space, its third quarter profits dropped by 93 percent compared to last year. According to its earnings report, AMD earned $66 million in profits in Q3 on around $5.6 billion in revenue. That’s not a particularly impressive figure on its own, but it gets worse when you compare it to its Q3 performance last year, where its profits were $923 million on $4.3 billion in revenue. AMD says it missed its targets for the quarter because of “the softening PC market and substantial inventory reduction actions across the PC supply chain” and that a big factor in its decreased profits is the accounting it’s doing after acquiring chip company Xilinx in February for an estimated $50 billion. The company did see growth in a few areas. While the market for gaming GPUs isn’t as hot as it was back when they could be used to mine Ethereum, AMD says its gaming segment was up by 14 percent, or $1.6 billion, thanks to “higher semi-custom product sales.” That’s likely a reference to the chips powering consoles like the PlayStation 5, Xbox Series S and X, and Steam Deck. The company also saw a 45 percent jump year over year for its data center division, where it says its Epyc chips have been doing well, and its embedded business got a massive boost thanks to that Xilinx acquisition. AMD is slated to announce a new generation of those processors on November 10th and is also slated to announce a new architecture for its GPUs on the 3rd. According to AMD’s CEO Lisa Su, who spoke on the company’s earnings call, the company is also betting on lots of people buying consoles as we head into the holiday season. AMD isn’t the only chip company that’s hurting right now. Intel’s Q3 profits were also down by 85 percent year over year, and the company is planning on making huge cuts to spending, which will involve laying off employees. We won’t know how Nvidia, AMD’s competitor in the GPU space, has weathered until it announces earnings on November 16th. AMD’s profits have cratered as the PC and crypto miner markets slow down
  12. Considering the horrors of the recent Nvidia RTX 4090 power connector fiasco, potential buyers who are afraid of their cards burning up have been holding off to see what AMD will offer. The wait isn't long as Team Red has an announcement planned for November 3rd. For those unware of the issue, a lot of Nvidia RTX 4090 12-pin connectors are breaking and in worst case scenarios, they are catching fire. Thankfully for those too afraid to proceed with a 4090 purchase, AMD had already confirmed it is not going to be using this type of power connector due to the many hazards associated with it. The confirmation came via SVP and GM of AMD Radeon, Scott Herkelman: Hence with the launch nearly upon us and with official confirmation that no 12-pin will be present on next gen AMD cards, it was only a matter of time for the reference card designs to pop up. We have them now courtesy of Twitter user HXL. It looks like there are two card designs in question here with one of them using the typical cooler shroud with the "R" representing Radeon. The other one has an interesting logo though both of them seem to feature the same axial fan design. Of course the more interesting thing is the apparent use of the more common dual 8-pin power connectors which is currently also present on RX 6000 series, just like Herkelman had said. This is the tried and tested method that works and it may be wise of AMD to be re-using this design. The dual 8-pins will be providing the AMD RDNA 3 reference GPU with a power headroom of 375W. This is far less than the 450W TGP (typical graphics power) of the RTX 4090. In terms of horsepower, RDNA 3 is expected to have a big jump in typical raster performance, though Nvidia is expected to be ahead in terms of ray tracing performance.

  17. As demand for PCs, GPUs, and cloud servers falters, Samsung and AMD join Intel and Nvidia with warnings of a growing semiconductor industry sinkhole. The downturn in the chip industry started in the summer months, as crypto crashes caused blockchain miners to flood the market with previously hard-to-find graphics cards. Almost overnight, demand eased up and caused graphics hardware prices to drop by almost half. Nvidia’s CEO Jensen Huang admitted in August that the company made too many graphics cards that now it has to sell them for less money. But Nvidia isn’t alone in this mess. Just last year, the only story about chips was that manufacturers couldn’t make enough of them to meet the strong demand for consumer electronics, cars, and other products that require semiconductors. But even as shortages continue for certain types of semiconductors, the story is becoming more nuanced, especially for giants like Samsung and AMD, who were flying high on revenues and profits in 2021 and into 2022. Now they are being bowled over by a tide that similarly swept up Nvidia and Intel this summer. As reported by Bloomberg, this week, Samsung is reporting a 32 percent sales guidance cut, while AMD warned investors it’s going to miss its previous forecast by about $1 billion. Slumping PC sales provide an obvious explanation for why processors from AMD and Intel are not in as high demand as they were early in the pandemic. Everyone simultaneously had an incentive to upgrade their laptops, gaming machines, and work-from-home setups, but now sales have slowed. One way manufacturers would like to turn that around, as Intel CEO Pat Gelsinger described on Decoder, is “to enable the PC ecosystem to have better products than what is done by the Mac. Period.” But that hasn’t happened yet, and for giants like Samsung, it doesn’t even begin to address the slowdown in demand for cloud servers and other machines. We emailed Gartner analysts Gaurav Gupta, Joseph Unsworth, and Jon Erensen, who confirmed to The Verge that other OEMs are also facing high inventory and low demand. “OEMs had piled inventory in 2021 and first half of 2022 — during shortages — panic buying / double-triple ordering, etc.” said the analysts. They also pointed out that these warnings from Samsung and AMD are due to the weak forecasts in PCs, smartphones, and consumer electronics, even though other areas like automotive are strong comparatively. Samsung’s memory and storage chip business made it the largest chipmaker over Intel in 2018, though the latter company primarily makes x86 processors. In July, Intel suffered losses and reported a 22 percent decline in revenue driven by low PC sales and operating losses to get its Arc GPUs out the door. Demand for chips of all kinds peaked at the turn of 2022, and companies like Samsung had record high revenue in 2021 with a 26 percent increase in profits (compared to its previous high in 2020) due to higher demand for consumer electronics like smartphones and TVs. But now WSJ reports that contract prices for DRAM chips dropped 15 percent, and 28 percent for NAND flash chips (the two main components Samsung makes), and cites a TrendForce prediction that those declines will continue to decline until nearly flattening by the end of 2023. There’s also concern about how the Biden administration’s just-revealed chip export restrictions to China could affect the semiconductor industry. Gartner’s analysts tell The Verge that this will slow down Chinese companies’ progress and hurt their long-term goals of becoming self-sufficient technology leaders. The new rules would require manufacturers like Intel and Micron to obtain a license to export semiconductors and chip-making equipment to Chinese companies as part of an effort reportedly intended to impair Beijing’s military and technological capabilities. Samsung and AMD’s profit slump suggests industry trouble for chipmakers
  18. Just as Blizzard prepares to launch its latest game later today, AMD has fired out a new graphics driver with official support. While a little lighter than usual, the new AMD Software: Adrenalin Edition 22.10.1 release has a couple of fixed issues included in it too. Following the original Overwatch's shutdown yesterday, Overwatch 2 goes online today, October 4, as a fully free-to-play experience. Those seeking to jump into the hero shooter with a graphics solution from the red team will want to update to this driver before doing so for optimal performance and stability. AMD has not given details on the exact improvements players will gain with it, unfortunately. As for the fixed issues, those looking forward to the upcoming Street Fighter 6 Beta will appreciate a crash fix that's included in here. Here are the two bug fixes: GPU for image processing option may not be available using Adobe® Lightroom® on Radeon™ RX 6000 series GPUs. App crash may be experienced in Street Fighter™ 6 Beta. Known issues are below. Note that some bugs are specifically listed to be fixed with the next driver version, 22.10.2, sometime later this month: Radeon™ Super Resolution may fail to trigger after changing resolution or HDR settings on games such as Nioh™ 2. Oculus dashboard menu and rendered controllers may appear bouncing/wobbly on Oculus Quest 2 with some AMD Graphics Products such as the Radeon™ RX 6800 XT Graphics. GPU utilization may be stuck at 100% in Radeon performance metrics after closing games on some AMD Graphics Products such as Radeon™ 570. While previewing the timeline in VEGAS Pro™, some colors may appear inverted. Chromium-based browsers may experience video stuttering on extended monitors with mixed refresh rates using Radeon™ RX 6000 series GPUs.

  19. At the end of August, AMD unveiled its Ryzen 7000 series desktop CPU lineup based on the Zen 4 micro-architecture. And although the excitement around it has been somewhat muddled down by Intel's 13th Gen Raptor Lake-S lineup which has come out guns blazing with lower prices, it does look like Zen 4 also has some redeeming qualities that enthusiasts would be keen to consider. Fellow media outlet Phoronix decided to test the new Ryzen 9 7950X, which is the flagship Ryzen 7000 SKU, with the various CPU vulnerability mitigations and more turned on and off. And the results are somewhat surprising in a good way for AMD. In the default state where the mitigations are enabled, the new Zen 4 chip actually manages to win by a bigger overall margin than with the mitigations disabled. Phoronix says: With Zen 4 you can still boot the kernel with mitigations=off to disable the SSB, Spectre V1, and Spectre V2 mitigations applied while leaving the system in a "vulnerable" state. While many route to the mitigations=off approach to avoid the performance penalties attributed to the different mitigations, in the case of AMD Zen 4 on the Ryzen 9 7950X it's not actually beneficial. Here is a full breakdown of the all tests showing the performance advantage of the two scenarios: Here is the geometric mean of the results where the default (mitigations enabled) state has clearly won more. Out of the total 190 tests conducted in this evaluation, the default state managed to win nearly 72% of the tests. Overall, it looks like AMD has clearly built on top of what it had achieved with Zen 3. The previously tested 5950X had actually managed to fare better than tested Intel CPUs with the retpoline patch.

  20. You can spend as much on a board as some people do on their whole PC. The MSI MEG X670E Godlike raises interesting questions, like, "could God make a motherboard so expensive that even He could not afford it?" MSI Building a PC around a new processor is expensive at the best of times, and that's triple-true of AMD's new Ryzen 7000 chips. AMD has started with its $300-and-up high-end chips, leaving mid-range options until next year. The CPUs only support DDR5 RAM, which is still more expensive than DDR4 at the same capacities. And the first round of motherboards that include the new AM5 CPU socket are here, and they're pretty expensive. The cheapest motherboard currently available from the likes of Newegg and Micro Center is the ASRock X670E PG Lightning, which, despite being the least expensive motherboard available, is an X670E board that will support PCIe 5.0 GPUs when they eventually arrive (even the newly announced GeForce RTX 4000-series still uses PCIe 4.0). The motherboard is missing a few features we like to see—no built-in Wi-Fi and Bluetooth, limited audio outputs, relatively small heatsinks for the voltage-regulator modules (VRMs) and other components—but it does have four M.2 SSD slots of varying speeds and plenty of hookups for case fans and front USB ports. If it's something you care about, the cheapest X670E board with Wi-Fi is also one of ASRock's, the X670E Pro RS, available for $280 at Newegg and Micro Center. AMD's Socket AM5. Andrew Cunningham As you go up in price toward the $500 mark, you start to see more of the additions that high-end boards are known for: larger heat sinks for the VRMs and, often, large one-piece metal heatsinks that cover more of the SSD slots and make the board look a bit cleaner inside a case with a side window. The Asus ROG STRIX X670E-F ($450), Gigabyte X670E Aorus Master ($500), and MSI MPG X670E Carbon Wifi ($480) are in this cohort, with their big, flashy RGB heatsinks. Compared to the lower-end boards, they also tend to have more USB-C ports on the back and a higher ratio of USB 3.x ports to USB 2.0 ports. Fans of tiny builds will be disappointed to see that there's just one mini-ITX AM5 board available so far, and it's pretty pricey: the Asus ROG STRIX X670E-I Gaming WiFi ($470) looks capable but also a bit weird, with an odd external hub called the "ROG Strix Hive" and a protruding daughterboard for USB 2.0 port headers, the front panel headers, and some SATA ports that may be an awkward fit in some especially small ITX cases. The Asus ROG STRIX X670E-I WiFi has an odd protruding daughterboard (right) for USB 2.0 headers, SATA ports, and the front panel header, which could cause problems for some tiny ITX cases. Asus The award for "most absurdly expensive motherboard" goes to the MSI MEG X670E Godlike, which at $1,300 is nearly twice as expensive as the next-most-expensive board. A hulking black monolith, this board is coated in shiny heatsinks and attempts to justify its price by including a riser card for additional PCIe 5.0 SSDs and a built-in 10Gbps Ethernet port. Prices won't be this silly forever—or even (hopefully) for very long. This first wave of boards is heavily tilted toward the more-expensive X670E variant (20 boards on Newegg, versus just four X670 boards), which need to meet the more robust signaling requirements of PCI Express 5.0 for the graphics slot. In October, AMD will also launch B650 and B650E boards, which only use a single chipset die whereas X670 uses two—these motherboards ought to bring AM5 support well below $200 while still delivering good performance. Next year, as DDR5 prices steadily come down and AMD launches more midrange Ryzen 7000 series CPUs, it should be easier to recommend an AM5 build to budget-conscious buyers. AMD plans to support AM5 until at least 2025, so a board that you buy now ought to be eligible for at least a few new CPUs in the next few years, too.

  21. Just a week after AMD issued the 22.9.1 graphics driver for those on the red team, the company is back with another release, this time the AMD Software: Adrenalin Edition 22.9.2. The driver comes with support for its latest CPU lineup as well as the full release of Grounded. Those rocking one of the brand-new AMD Ryzen 7000 Series CPUs with Radeon Graphics will want to update to this driver to gain official support. Meanwhile, Obsidian Entertainment's survival game Grounded is coming out of Steam Early Access and Xbox Game Preview later today with a full 1.0 release, and this is the driver that's recommended for a smooth experience. Being such a quick release after the previous driver, no bug fixes are mentioned in the latest release notes. This should still have all the fixes, including the long-awaited one for broken Enhanced Sync, from the 22.9.1 driver. Users can upgrade to the new AMD Software: Adrenalin Edition 22.9.2 driver via the Radeon Settings app on Windows 10 and 11. The driver is available in the Optional section of the app. A direct link to download the driver can be found on the official release notes. Following Nvidia's RTX 4000 series unveiling recently, AMD is also planning on a launch event for its next-generation RDNA 3-powered RX 7000 series graphics cards, which is set to kick off on November 3. Rumors suggest that the top-end RX 7900 XT will be more than twice as powerful as AMD's last-generation flagship products.

  22. A little fix for CPUs that didn't properly sleep had decades-long consequences. AMD has come a long way since 2002, but the Linux kernel still treats modern Threadrippers like Athlon-era systems—at least in one potentially lag-inducing respect. AMD engineer Prateek Nayak recently submitted a patch to Linux's processor idle drivers that would "skip dummy wait for processors based on the Zen microarchitecture." When ACPI support was added to the Linux kernel in 2002—written by Andy Grover, committed by Linus Torvalds—it included a "dummy wait op." The system essentially read data with no purpose other than delaying the next instruction until the CPU could fully stop with the STPCLK# command. This allowed for some power saving and compatibility during the early days of ACPI implementation when some chipsets wouldn't move to an idle state when one would expect it. But today's Zen-based AMD chips don't need this workaround, and, as Nayak writes, it's hurting them, at least in specific workloads on Linux. Testing with instruction-based sampling (IBS) workloads shows that "a significant amount of time is spent in the dummy op, which incorrectly gets accounted as C-State residency." The CPU, seeing all this low-effort dummy work, can push into deeper, slower C-State, which then makes the CPU take longer to "wake up," especially on jobs that require lots of switching between busy and idle states. Nayak ran tests in tbench on a dual-socket Zen3 system against the baseline Linux kernel, a kernel with the C2 state entirely disabled, and a kernel with the dummy wait operation patched out. His patched version saw a 1,390 percent increase in minimum MB/s throughput and a 51 percent increase in mean MB/s over the baseline kernel, often just a little behind having C2 disabled entirely. Intel systems have avoided AMD's legacy curse, as they use an MWAIT-based system for at least a decade, per the Phoronix blog. That led to an urgent patch submitted by Dave Hansen of Intel. His solution was to limit "dummy wait" to Intel systems, where it would not affect "remotely modern Intel systems," and add comments to the kernel's idle drivers that spell out what's happening—and encourage those reading to "consider moving your system to a more modern idle mechanism." If an urgent patch removing or limiting "dummy wait" is submitted this week, it could likely make the Linux 6.0 kernel, which Torvalds expects to ship next week. 20-year-old Linux workaround is still slowing down AMD systems
  23. Ryzen 7000 CPUs use a new platform—with plenty of changes. AMD's Ryzen 7000 launch is bigger than just the processors. The processor architecture is changing, but it's also being accompanied by changes to everything from the chipset to the physical socket that the chips plug into. The last time this many things changed at once was back in 2017, when the first-generation Ryzen chips originally launched. So we're publishing two Ryzen pieces today. One is a look at the actual chips' performance and power efficiency, located here. This one will focus on all the other changes, including the ones that will be with us long after Ryzen 7000 is old news. We'll split this piece up into four parts that cover the four major components of the Ryzen 7000 launch: 1) the Zen 4 CPU core, 2) the on-chip I/O die that supports the CPU's non-CPU features and handles internal connectivity, 3) the 600-series chipsets that handle most external connectivity, and 4) the physical AM5 socket that will outlive all of the other components by a few years. Zen 4 CPU, in brief The high-level Zen 4 architectural overview. Zen 4 is a revision of Zen 3, where AMD called Zen 3 a "ground-up" redesign. Most of the performance gains come from front-end improvements that keep the processor fed. Though there have been some execution improvements as well. AMD has increased the size of the load queue and bumped up some cache sizes. AMD promises roughly 29 percent faster single-core CPU performance in Zen 4 relative to Zen 3, which the tests in our review more or less back up. A little under half of this increase comes from architectural improvements that boost Zen 4's instructions-per-clock (IPC) count, while the rest comes from clock speed boosts. Clocks for Ryzen 5000 processors all peaked just short of 5 GHz, while Ryzen 7000's CPUs all boast peak clock speeds well above 5 GHz. On the architecture front, AMD says that Zen 4 is a refinement of Zen 3 rather than a ground-up redesign. Many of the building blocks of Zen 3 are still present: eight-core Core Complex Dies (CCDs) made from one eight-core Core Complex (CCX), which shares a large 32MB cache among all eight CPU cores (or six, in the 7600X and 7900X). Ryzen CPUs consist of either one or two CCDs and an I/O die (IOD), linked with AMD's Infinity Fabric interconnect. The bulk of Zen 4's IPC improvements come from an improved front-end design, with a faster branch predictor that can predict two branches per clock cycle instead of one, as well as larger L1 and L2 Branch Target Buffer caches and Op Cache. Zen 4 also features improvements to the load/store unit, which has a 22 percent larger load queue and a larger L2 cache. Each individual CPU core inside the CCX also has its own 1MB chunk of memory—twice as much L2 as each Zen 3 core. Some of Zen 4's increased performance comes from a doubling of L2 cache per core, from 512 KB to 1 MB. AMD To make these additions and improvements without increasing power usage, Zen 4 CCDs are manufactured on a 5 nm process from TSMC, an upgrade from the 7 nm process used for both Zen 2 and Zen 3. This enables Zen 4 CCDs to use nearly 57 percent more transistors than Zen 3 CCDs (from 4.15 billion to 6.5 billion) while making die sizes smaller overall (70 mm squared, down from 80.7 mm; it's also smaller than the 74 mm squared Zen 2 CCD die). Because the CCX and CCD core counts are the same as in Zen 3, this means that core counts stay level for another generation—you can get as many as 16 cores in the Ryzen 9 5950X CPU, spread across two fully enabled CCDs. Sketchy rumors suggest that Zen 5 might switch to using a hybrid architecture split between large performance cores and smaller efficiency cores, as both Apple and Intel have done, but for now, every core in a Zen 4 CCD is the same size and has the same performance and capabilities. A rough breakdown of Zen 4's IPC improvements, which combine with clock speed boosts to outrun Zen 3 by an average of 29 percent. AMD Aside from general performance improvements, Zen 4 also adds support for AVX-512 processor extensions, both the foundational AVX512F instructions and a handful of others. But rather than building a large 512-bit SIMD block as Intel did, Zen 4 will process AVX-512 instructions by running them through its 256-bit SIMD. This comes with trade-offs—Zen 4 will need two clock cycles to process AVX-512 instructions instead of one, but unlike Intel CPUs with AVX-512 support, AMD's design also won't use nearly as much power or generate as much heat, allowing it to keep the clock speed higher. (It doesn't take up as much die space, either.) By AMD's admission, its AVX-512 implementation won't be as fast as Intel's, but it feels like AMD made the right trade-offs given the niche-ness of AVX-512 support in the first place. Despite creating and pushing the instructions, Intel's 12th- and 13th-generation CPUs officially don't support AVX-512 at all, so even a less-speedy implementation from AMD is better than what Intel is currently offering on the desktop. AMD's AVX-512 implementation uses a 256-bit wide SIMD, which means it needs two clock cycles to execute them but can run at higher clock speeds with lower power use and temperature than Intel's implementation; it also saves on die space. A list of the AVX-512 instructions supported by Zen 4. As for what's next for Zen 4, AMD's roadmap lists separate 3D V-Cache versions of Ryzen 7000, and we know that mobile processors are coming in the form of the "Phoenix" and "Dragon Range" chips. Less-expensive versions of the Ryzen 7000 CPUs will hopefully follow at some point as well—we had to wait almost a year and a half for $200-and-under Ryzen 5000 CPUs on the desktop, but hopefully the manufacturing and supply chain pressures that made that decision necessary have cleared up enough that we see cheaper Zen 4 chips a bit sooner. The I/O die The new Zen 4 I/O die (IOD) is its first upgrade since the Ryzen 3000 series. It uses a new 6 nm process and integrates a DDR5 memory controller and an integrated RDNA 2 GPU. AMD Zen 4 is an impressive jump from Zen 3, but if anything, the I/O die (IOD) is an even bigger departure from previous chips. In AMD's processors, the IOD is a separate piece of silicon on the CPU package that has been manufactured on a more-mature, less-advanced process than the CPU dies. The benefits of scaling down these chipset functions aren't as noticeable or important as they are for the CPU cores themselves, so AMD keeps them physically separate, tied together via the Infinity Fabric interconnect. Both Zen 2 and Zen 3 desktop processors used the same 12 nm I/O die, which means it has been a couple of generations since we've seen major improvements here. The Ryzen 7000 IOD has a new DDR5 memory controller with support for ECC RAM in motherboards that also support ECC RAM (but, unlike Intel, there's no DDR4 controller—it's DDR5 or bust). The processor can supply up to 28 lanes of PCIe 5.0 bandwidth, though motherboards with non-"Extreme" chipsets will still use PCIe 4.0 for the GPU slot. There's a new integrated GPU, a first for non-APU Ryzen processors. The IOD also includes its own USB controller with support for up to four 10Gbps USB 3.2 Gen 2, included partly to enable DisplayPort-over-USB-C connections to the integrated GPU and the built-in USB flashback functionality. Selecting an optimal RAM speed The DDR5 memory controller supports DDR5-5200, as far as officially sanctioned JEDEC memory standards go. But as with most motherboards these days, one-click RAM overclocking is both supported and encouraged. AMD recommends a "sweet spot" of DDR5-6000 to get the best performance out of Ryzen 7000. Explaining why is a bit complex. In short, RAM speed (MCLK), memory controller speed (UCLK), and the speed of the Infinity Fabric interconnect (FCLK) are all tied together, part of the reason why Ryzen's performance has historically been more sensitive to memory bandwidth than Intel's. In Ryzen 3000 and 5000 CPUs, the recommended strategy was usually to try to keep MCLK, UCLK, and FCLK running at the same speed (also called a 1:1:1 ratio). If you set your memory clock speed too high for the Infinity Fabric to keep up, the Infinity Fabric clock speed could actually fall back to a lower speed, introducing latency that could offset the performance benefit of the faster memory (and wasting whatever extra money you spent on super-fast RAM). For these CPUs, AMD typically recommended DDR4-3600 as a sweet spot, since the RAM, memory controller, and Infinity Fabric could all easily handle an 1800 MHz clock speed, and DDR4-3600 was generally a lot cheaper than faster RAM kits while being only slightly more expensive than slower RAM kits. For Ryzen 7000, higher RAM speeds for DDR5 make a 1:1:1 ratio harder to achieve, so AMD recommends keeping the memory clock and memory controller clock (MCLK and UCLK) synced at 1:1 while the Infinity Fabric (FCLK) runs at a slightly elevated speed of 2,000 MHz (the default ranges between 1,600 and 1,800 MHz). For RAM speeds above DDR5-6000, AMD says the memory controller clock can no longer keep up, so it drops to a 2:1 ratio. Spend money on a (fictitious, currently) DDR5-8000 kit, and you'd end up with a memory clock of 4,000 MHz but a memory controller clock of just 2,000 MHz, rather than the controller clock of 3,000 MHz you get with DDR5-6000, reducing or erasing whatever performance benefits you wanted to achieve by using faster RAM. The integrated GPU: Two RDNA GPU cores, mostly USB-C outputs The RDNA2 GPU in the IOD is optimized for everything except raw performance, mostly display outputs and video encoding and decoding. The IOD's USB support means that your motherboard's USB-C ports should be able to handle a display signal and data, where many motherboard USB-C ports today will only handle data. AMD For the first time, all of AMD's CPUs include a basic integrated GPU. All four of the CPUs introduced today include a GPU with two compute units (CUs) built into the I/O die and based on the same RDNA2 architecture as the Radeon RX 6000 dedicated GPUs and the Ryzen 6000-series integrated GPUs. These GPUs are primarily made with CPU-focused workstations and business desktops in mind, systems where graphics performance is non-critical but being able to drive a couple of monitors in a small power envelope is handy. For anyone who throws a dedicated GPU into their system, you can either ignore the integrated GPU altogether or keep it turned on so you can use its video encoding and decoding blocks or its display output capabilities. As with Intel's integrated GPUs, AMD's can operate in hybrid mode, using a dedicated GPU to render content that is then displayed on a monitor connected via the integrated GPU. AMD emphasized over and over again that these aren't meant to be gaming GPUs, nor are they replacements for the G-series APUs that AMD releases. Those APUs typically contain somewhere between six and 12 GPU cores, still nowhere near what a dedicated GPU includes but substantially more than the Ryzen 7000 I/O die. In our review, we found that the new Ryzen GPU and Intel's current UHD 770 GPU perform pretty similarly. As a gaming GPU, 2D performance is fine, performance in older games is OK, and it's fine for Minecraft—but expect 720p and low settings in more modern titles. Andrew Cunningham But these still are RDNA-based GPU cores, and they do confer benefits even for gaming systems with dedicated GPUs. The integrated GPUs will support a maximum of four separate display outputs, one over HDMI 2.1, plus another three over USB-C using DisplayPort alt mode. This is a nice change from the status quo, where desktop USB-C ports can frequently only handle data rather than doubling as display outputs as they do on most laptops. AMD says that the integrated GPU can drive up to three 60 Hz 4K displays at once, but it was noncommittal about higher-than-60 Hz output. In our testing, the GPU had no issue simultaneously driving one 4K display at 60 Hz over HDMI and one 4K display at 144 Hz via DisplayPort-over-USB-C, so they can clearly do a bit better than AMD says. The new GPUs share other features in common with other RDNA2 GPUs, too. They support variable refresh rates via FreeSync. Their video encoding and decoding block supports decoding of AV1 (and VP9) video streams, but you'll still need an Intel Arc or Nvidia RTX 4000-series GPU to support hardware-accelerated encoding of AV1; the encoding block does support 8- and 10-bit H.265 and H.264 video. They can even do hardware-accelerated ray tracing, though they're so slow that there is no practical benefit to it. Built-in USB flashback support One other handy, common-sense addition to the I/O die is built-in USB flashback support—the ability to flash your BIOS to a newer version even if the current version doesn't support the CPU you have installed. Not having this feature could have been a huge headache when new AM4 processors launched; if you wanted to buy a modern CPU with a slightly older motherboard to save some money, you could never assume that the motherboard would actually ship with a BIOS that supported that CPU, even if the motherboard maker had released an updated BIOS already. AMD's only official solution for this problem on AM4 motherboards was kludgy and involved making a warranty claim against your new processor to request an old low-end CPU loaner as a "boot kit." Midrange-to-high-end motherboards ended up implementing CPU-less BIOS flashing via USB to get around this, but this is the first time AMD has implemented it into the platform directly. AMD tells us it expects some manufacturers to stick with their own USB flashback implementations, and it isn't requiring motherboards to actually enable the built-in version either; motherboard makers will need to implement some kind of physical switch or jumper to enable the feature, and AMD isn't making anyone do it. We may still see some budget-y motherboards ship with no version of USB flashback, AMD-enabled or otherwise. But the company hopes that having the capability built in will end up pushing most boards to include it. Socket AM5: More power, support through 2025 AMD wants Socket AM5 to carry it into 2025, and possibly beyond. Andrew Cunningham Chipsets and processors will change, but Ryzen 7000 ushers in the successor to 2017's AM4 processor socket. Socket AM5 is a 1718-pin land-grid array (LGA) socket, meaning that its pins are on the motherboard instead of on the CPU. One thing the additional pins allow for is more power delivery—from a rated maximum of 142 W for AM4 to a maximum of 242 W for AM5. This also lets AMD increase the TDP ratings of newer Ryzen CPUs, from 105 W to 170 W. These power ceilings are far above what you need to get good performance out of Zen 4; the Ryzen 7950X in our review performed well even when set to a 105 W or 65 W TDP instead of its normal 170 W, and the 7600X performed nearly identically set to 65 W or its default 105 W. But if AMD intends this socket to last until at least 2025, it will probably see Ryzen 8000 or Ryzen 9000 processors someday, too; if AMD wants to increase performance without the benefit of a new manufacturing process, or if it wants to increase the maximum number of CPU cores from 16 to something higher, or if 3D V-Cache chips continue to run hotter and more power-hungry than their V-Cache-less counterparts, AM5 gives AMD a good amount of future headroom. Unlike Intel's LGA 1700 socket, AMD has been able to keep the dimensions of its CPU packages the same in the move from AM4 to AM5, which means that very nearly all existing CPU coolers with AM4 mounting hardware should be able to mount to AM5 processors and motherboards. Both a cheapo Vetroo V5 air cooler and a Corsair iCue H115i AIO pump worked just fine with the AM5 CPUs in our testing. AMD has committed to support socket AM5 through at least 2025, which implies it will probably see at least two major Ryzen CPU refreshes (plus a bunch of minor releases in between). Three years sounds relatively paltry compared to AM4, which had a solid five years of support, but AMD only promised to support AM4 through 2020 back when it launched in 2017. There's precedent for underpromising and overdelivering on the CPU support front. Four chipsets are actually two chipsets (that are actually one chipset) AMD's baseline B650 chipset is the basic building block used in B650E, X670, and X670E boards. AMD All system I/O that the processor's built-in I/O die doesn't handle is still handled by the chipset, an external die that is connected to the CPU over the PCI Express bus. AMD has only made a single physical chip for this generation, which is offered in a total of four configurations. Let's start with the lower-end chipset since it's the basic building block AMD is working from. The B650 chipset is connected to the CPU via four PCIe 4.0 lanes. It can enable as many as 12 extra USB ports beyond what the IOD supports, plus eight general-purpose PCIe 4.0 lanes that can be used to support additional M.2 slots, Wi-Fi modules, LAN ports, or other internal accessories. And another four PCIe 3.0 lanes can be used to support another NVMe slot, 6Gbps SATA ports, or some combination of both. Eight of the Ryzen CPU's 24 PCIe 5.0 lanes are used to support PCIe 5.0 SSDs, while 16 more run to the main PCIe slot you use for GPUs. In a standard B650 motherboard, the GPU slot will only run at PCIe 4.0 speeds. The next chipset, B650E, is identical to B650, but motherboard manufacturers will ensure that the system's main PCI Express x16 slot can also handle PCIe 5.0's increased signaling requirements. This is the only difference between B650 and B650E. All AMD X670 and X670E motherboards use a pair of identical chipset dies connected via a four-lane PCIe 4.0 interface. Only X670E chipsets will support PCIe 5.0 in the GPU slot. X670 boards will only support PCIe 5.0 for M.2 SSDs. AMD The X670 chipset uses the exact same die as the B650—there are just two of them, one referred to as the "upstream chipset" and the other designated the "downstream chipset." Everything about an X670 board's I/O is exactly doubled compared to B650, except you only get 12 general-purpose PCIe 4.0 lanes where you'd expect to get 16. That's because four of the chipset's PCIe 4.0 lanes are used to connect the upstream and downstream chipsets, in addition to the four used to connect the chipsets to the CPU. As with the B650E, X670E boards are identical to X670 boards, but they support PCIe 5.0 speeds for the GPU slot rather than PCIe 4.0. AMD reiterated to us that all four of these chipsets will be capable of overclocking, as they always have been—there's no artificial gating of overclocking to higher-end chipsets and boards. But the X670 chipsets are still more likely to be included in boards with more robust power delivery and better voltage regulator modules—things you'll want if maximizing an overclock is really important to you. EXPO memory overclocking profiles Automated memory overclocking has become a popular way to wring out slightly higher performance from desktop systems in the last few years, especially for AMD systems where increased RAM speed can also increase the speed of the Infinity Fabric interconnect that allows the different CPU dies and the I/O die to communicate. The main standard that most memory manufacturers and motherboard makers unified on is Intel's Extreme Memory Profile spec—RAM makers ensure that their sticks will run at standard DDR4 or DDR5 speeds out of the box, but XMP sticks also have faster speeds and tighter timings programmed into them. Users can head into their BIOS and load up these profiles with one click, "overclocking" their memory without having to worry about crashes or instability (at least, in theory). With Ryzen 7000, AMD is introducing its own memory profiles, dubbed Extended Profiles for Overclocking (or EXPO). Rather than piggybacking off of XMP, AMD says that EXPO-certified RAM has been tested specifically with AMD's processors, allowing manufacturers to make additional speed and timing tweaks if they find that some settings work better with AMD's processors than Intel's. For users, the end result—one-click memory overclocking via the BIOS—is the same. Ryzen 7000 CPUs and AM5 motherboards will be able to use regular XMP profiles, too. There's nothing blocking RAM makers from supporting both XMP and EXPO profiles in the same kit, but it's equally likely that Intel motherboards will just pick up support for EXPO profiles as well as XMP. Gigabyte and MSI have already announced that their Z690 and B660 motherboards will add EXPO support, and we suspect that other manufacturers will get on board. For now, be careful about trying to use an EXPO kit in an Intel board—the G.Skill Trident Z5 Neo EXPO RAM kit that AMD sent with our Ryzen review hardware did show us an XMP profile in the Gigabyte Z690 board we tested with, but the system wouldn't actually boot until I had dropped the RAM speed from DDR5-6000 down to DDR5-5800 (it ran fine at its rated speed on our AM5 system).

  24. AMD has released its latest Windows graphics beta driver with Adrenalin 22.9.1. The new release finally fixes an age-old Radeon bug which was causing black screen issues in games and videos when the Enhanced Sync option was used. The feature is meant to deliver the best of both worlds between FreeSync and V-Sync. It is said to minimize screen tearing like FreeSync does while also decreasing the latency introduced by traditional V-sync. The new driver also adds support for Call of Duty: Modern Warfare II Open Beta. The full changelog is given below: Highlights Support for Call of Duty®: Modern Warfare® II Open Beta. Fixed Issues Enhanced Sync may cause an intermittent black screen to occur during gameplay and video playback using extended displays and toggling Enhanced Sync.

  25. October 2022 will be a busy month for Microsoft. The company plans to ship the first "moment" update for Windows 11 and release Windows 10 version 22H2. Besides, customers expect Microsoft to host a Surface event and unveil next-generation Surface devices. As we get closer to the event, more leaks reveal details about upcoming computers from Microsoft. As reported by WinFuture, the software giant plans to change what CPUs it picks for the next Surface Laptop refresh. We already know that Microsoft wants to merge the Surface Pro and Pro X lineups into a single device family, providing users with the option to pick an Intel or ARM processor. It is similar to how Microsoft lets you configure the Surface Laptop 4 with AMD and Intel CPUs. Unfortunately, it appears that the Surface Pro "5" will take away that privilege, leaving the device with only 12th Gen Intel processors. WinFuture claims they are not 100% sure Microsoft has decided to kill AMD-based Surface Laptops, so take this information with a healthy grain of salt, even though the source has a solid record of accurate leaks. Like every other Surface update, the upcoming computers will debut new chassis colors. Besides now-classical black and platinum, Microsoft plans to unveil "Forest" (green) and "Sapphire" (blue?) variants for the Surface Pro "9." Price-wise, the Surface Pro "9" will be available in Europe for roughly €1300 for the entry-level model with the Intel Core i5-1235U, 8GB of RAM, and 256GB SSD. The Surface Laptop "5" in its base 13-inch configuration will get a €1200 price tag and €1500 for the 15-inch variant. For now, the latest report contradicts rumors claiming that Microsoft is preparing a new Surface laptop with Ryzen 6000 processors. Other leaks point to an upcoming gaming-focused Surface laptop with only 12th Gen Intel Processors. Luckily, we are just a few weeks away from the event, so things will get clear soon. Microsoft reportedly ditches AMD processors for upcoming Surface Laptop
