  1. AMD 21.6.2 driver brings support for ray tracing on Doom Eternal, new Vulkan extensions AMD today has released its new Radeon Software version 21.6.2 display driver. The update is the second driver of this month and the major highlight of this release brings optimization for Doom Eternal that recently gained ray-tracing (RTX) and DLSS features and is available today. The driver also adds several new Vulkan extensions. They are: VK_EXT_custom_border_color This extension allows applications to specify a custom border color for when the sampler address mode VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_BORDER is used. VK_KHR_shader_subgroup_uniform_control_flow This extension exposes the availability of the SPV_KHR_subgroup_uniform_control_flow SPIR-V extension for shader modules use. The SPIR-V extension provides stronger guarantees that diverged subgroups will reconverge. VK_EXT_color_write_enable This extension allows applications to selectively enable and disable writes to output color attachments via a pipeline dynamic state. This has the potential to reduce pipeline counts for increased efficiency. As usual, the driver brings a few fixes for bugs which are listed below: While playing MechWarrior 5™: Mercenaries on DirectX® 11, visual artifacts may be observed on some AMD Radeon graphics products such as Radeon RX 6000 series graphics products. An error message – Error 184 – may be received after running the AMD Auto-Detect and Install Updates utility program on Windows® 7 based systems. Adobe Substance 3D Painter™ may freeze while running this application on some AMD Radeon graphics products such as Radeon RX 6900. There are also several issues, both new and some old, that remain unresolved: Some users may experience elevated memory usage by AMD User Experience Program. A temporary workaround is to opt-out of the AMD User Experience Program. Learn more from AMD here on how to opt out of the program. Resident Evil Village™ may experience an intermittent application hang or TDR on AMD Radeon VII graphics products in the first mission of the game. Enhanced Sync may cause a black screen to occur when enabled on some games and system configurations. Any users who may be experiencing issues with Enhanced Sync enabled should disable it as a temporary workaround. Connecting two displays with large differences in resolution/refresh rates may cause flickering on Radeon RX Vega series graphics products. An Oculus service error may be received on Radeon RX 5000 & 6000 series graphics products which prevents the Oculus Link setup software from running. Radeon performance metrics and logging features may intermittently report extremely high and incorrect memory clock values. If Ryzen Master is not detected in Adrenalin software after installation, a system restart may be required. If Blue or Black screen is observed in mobile systems, temporarily disable Enhanced sign-in A driver mismatch error may appear when two versions of Radeon software (Windows Store & AMD Support versions) are installed on your system. As a temporary workaround, launch the Windows Store version of Radeon software. A Blue or Black screen may be observed after updating to the latest Radeon Software. A workaround is to disable core isolation. AMD is investigating a D3 code that may be seen in some motherboard after updating to the latest Radeon Software. Lower than expected performance may be observed on select AMD Athlon™ mobile systems. The AMD Link for Windows issue still remains: Intermittent grey frame corruption might be observed when streaming with HEVC on certain configurations via an Internet connection. A workaround is to use the AVC encoding setting instead. With its previous release version 21.6.1, AMD dropped support for pre-Windows 10 systems and pre-Polaris graphics cards, and the new 21.6.2 is no exception. So for those with a compatible system who wish to update to this driver, you can find the download link on the official release notes page. For owners of Nvidia GPUs, a Game Ready GeForce driver for Doom Eternal RTX update was already released last week, which you can find here.

  2. AMD's Big Navi already showing FineWine magic, RX 6900 XT almost on par with RTX 3090 AMD FineWine Technology, as the community loves to call it, is a situation where a Radeon GPU is seemingly able to catch up or even surpass its corresponding GeForce rival SKU due to the performance gains it undergoes during its life cycle. In essence, it gets better as it ages, something like a high-quality wine would do. The gains it achieves are a consequence of subsequent driver updates as well as more favorable game optimizations. The FineWine phenomenon generally starts to kick in a couple of years into a GPU generation. However, the RX 6000 series (Big Navi) GPUs, that launched last year and aren't even a year old at this point appear to be showing these signs already. According to a performance analysis done by German media 3DCenter, while both RTX 30 series cards, based on Ampere architecture, and the RX 6000 series, based on Navi 2X architecture, have gained quite a lot over launch day numbers, its the Team Red figures that are far more impressive. The data shows that on average, AMD cards have gained more than 10% performance in the last six months with the biggest gains seen at 1080p. Nvidia cards see the biggest improvement at QHD resolution likely indicating the CPU bottlenecks that was suggested by a report earlier. The performance gains of individual cards have also been presented for those interested to look at how each of the cards has done so far over its life span. There are three charts (click on them to enlarge) for this data one each for the resolutions 1080p, 1440p, and 4K. Overall, these are good signs for AMD and also for its fans and users and it's possible we could see this trend continue as it generally has done in previous generations. However, things could be different this time and Nvidia could fight back too. The graphics landscape is after all changing as new cutting-edge technologies like Ray-Tracing are taking shape, and for now, Nvidia clearly has the upper hand in this.

  3. AMD Socket AM5 motherboards allegedly launching next year AMD launched the Socket AM4 platform five years ago in 2016 to usher in the era of DDR4 memory. Five years on and we have started hearing murmurs of its succeeding Socket AM5 platform that will add next-gen DDR5 support. The latest report today comes from UNIKO's Hardware according to which the upcoming socket will launch next year in 2022 around the Q2 time frame. Socket AM5 is pretty revolutionary as it will reportedly come with Land Grid Array (or LGA) packaging and hence the pins will be on the socket instead of being on the processor. This will make AM5 the first mainstream AMD platform to feature the LGA package as the company already deals with boards based on LGA for its Threadripper HEDT processor lineup. The report also adds that Intel's upcoming Z690 chipset-based motherboards meant to work with the company's 12th gen Alder Lake-S CPUs will be launching towards the end of this year in Q4. This somewhat matches with what we had learned earlier from a leaked company roadmap slide. The mid-range, B660, and the entry-level H610, boards however are reportedly not launching until 2022.

  4. AMD's Zen 4 could be a behemoth with up to 128 cores in a single socket AMD's Zen 4 is the next big revision of the company's Zen CPU micro-architecture and lately, information related to the upcoming platform has been spilling out fast. According to the latest rumor today, each next-gen EPYC server processor based on Zen 4 (codenamed 'Genoa') will pack up to 128 cores, which is double that of what AMD offers in its current EPYC 7003 lineup. The image below shows the 64-core layout of an EPYC 7703 (Milan) processor: The rumor isn't completely new as earlier there were reports of Zen 4 allegedly having more than 64 cores with new instructions like AVX-512, BFloat16, and more. These new instructions are helpful for high-performance computing (HPC) and server workloads so the alleged addition of them definitely makes sense. Intel added AVX-512 instructions to its CPUs with the Rocket Lake architecture and the gains in compatible workloads are truly impressive. According to AnandTech, even an 8-core Rocket Lake-S part was able to win against a 64-core Zen 2 EPYC processor in 3D Particle Movement AVX-enabled benchmark. While Zen 4 and Genoa are still a while away, it is already known that fourth-gen EPYC processors will be deployed inside an upcoming exascale supercomputer dubbed "El Capitan". El Capitan is expected to release in 2023 and it will be used for overlooking U.S. nuclear research and operations.

  5. Here are more details on AMD's big.LITTLE CPU architecture leak Pretty much like Intel is doing, AMD too has been working on its own hybrid processor architecture consisting of big and little cores. We came to know about this from a leaked patent last year (via @Underfox3). Today we have new information on the development as Twitter user @Kepler_L2 has spotted one of AMD's new patents related to big.LITTLE published a few days back. The patent outlines how task processing between the two types of cores would be handled in this hybrid approach. According to this patent, the little cores will have a time threshold built-in and sensors will monitor the length of time it runs at its full clock speed. Once the threshold is crossed, the task will be handed over to the big core. A similar process would be carried out for memory-intense workloads if it runs at its highest frequency state for higher than the threshold time. That's because the idea behind the use of the little cores is to save power and running them at full speeds for long durations defeats that purpose. For the big cores, the implementation is exactly the opposite. In essence, if a workload running on the bigger core does not cross the threshold, the task is sent to the little cores since clearly so much processing power does not seem to be necessary for the workload. Going back to the patent from last year, the architectural block diagram of the big.LITTLE design approach was described in it. Both the cores will have their own dedicated L1 cache but they will share the pool of L2 between them.

  6. AMD's next-gen RDNA 3 performance jump rumored to be absolutely insane AMD's second-generation RDNA architecture (RDNA 2) was generally praised by reviewers for the performance and power efficiency gains it was able to achieve despite being on the same 7nm node as RDNA. However, this was AMD's first time implementing hardware-accelerated ray tracing (RT), and the results for this, compared to Nvidia's RT capabilities, were far less impressive. That is all set to change according to a report by RedGamingTech (RGT). The report claims that AMD's RDNA 3 ray tracing performance will get a significant uplift and will be very competitive with what Nvidia offers. It also adds that RDNA 3 will be utilizing a next-gen, "smarter" Ray Tracing IP 2 that could enable it to even leapfrog Nvidia's RT performance. The architecture will also feature new Machine Learning instructions. AMD hasn't forgotten about the rasterization performance of RDNA 3 either as a leakster on Twitter alleges that Navi 31, Navi 32, and Navi 33 will respectively offer 2.8x, 2.2x, and 1.5x times the performance of AMD's current best, the Radeon RX 6900 XT. Unknown at this point is how exactly AMD could be achieving this uplift. Whether the performance claims purported here mean the company will be adding more compute units (CUs) to the 80 units on the 6900 XT, or if the improvement is purely based on per CU architectural and clock gains. Or perhaps it's a combination of all of them. That said, it is important to note that this is all based on speculation and unconfirmed reports for now, so it is advisable to take these rumors with a grain of salt.

  7. AMD's next gen Socket AM5 may be LGA according to multiple leaks, Zen 4 details, and more AMD's Raphael is rumored to be the codename of AMD's Ryzen 7000 series of processors based on the Zen 4 micro-architecture. The next-gen processor is said to be introducing the company's next major socket revision dubbed "AM5" in the mainstream desktop lineup. The new socket AM5 is going to be significant for more than one reason. We already know from earlier leaks that DDR5 memory support will reportedly be coming to AMD with this socket. And now we learn that the Socket AM5, like Intel's, will be moving to Land Grid Array (or LGA) from the current Pin Grid Array (or PGA) packaging. This essentially means that pins, which have so far been on AMD's processors, will now be moved to the motherboard in AM5. Here's a rendering of how a Raphael CPU might look like from below: YouTuber GamersNexus (GN) has said today that it had received images of internal AMD slides related to Raphael last year but decided against releasing them to the public since the authenticity of those images couldn't be verified. However, after Twitter leakster 'ExecutableFix' also seemed to share similar information about two weeks ago, GN says he feels much more confident now to share these publicly. Bear in mind though that these slides are more than a year old at this point and some of this information on them like DDR4 memory support on AM5, has likely been updated since. With that aside, here are the rumored details of the two leaks we have so far: Socket AM5, LGA package, Zen 4 Core Core Chiplet Die (CCD) codename Durango, Zen 4 CCD based on 5nm while the I/O die will be 7nm, Ryzen 7000 desktop TDP up to 120W (may go higher up to 170W), Ryzen 7000 mobile 35-65W, DDR5 memory, 28 PCIe 4.0 lanes. AMD is expected to release Raphael in late 2022 or the year after since the company has its 7nm Zen 3+ based chips planned for launch later this year. Zen 3+ is likely to feature its new 3D-stacked V-cache which AMD unveiled at Computex. The new 3D V-cache is said to offer around a 15% average improvement in gaming performance. While the Ryzen 7000 series Raphael chips may be the first to use LGA on the mainstream platform, the company has always been using LGA packaging on its Threadripper-based HEDT lineup.

  8. AMD announces the Radeon RX 6000M series with RDNA 2 architecture Will AMD’s processor dominance extend to its GPUs? The new Radeon RX 6800M. AMD AMD has announced its long-awaited Radeon RX 6000M series of mobile GPUs, featuring its RDNA 2 architecture. Today’s release consists of three chips: the RX 6800M (configurable at 145W and above), the RX 6700M (up to 135W), and the RX 6600M (up to 100W). AMD says the flagship 6800M delivers the fastest AMD graphics for laptops yet; it claims the 6800M will run modern AAA games at frame rates that are comparable to or better than those of Nvidia’s mobile RTX 3080. It’s also purported to outperform Nvidia’s chip while gaming on battery. AMD says the RX 6700M will deliver up to 100fps “in popular games” at 1440p resolution. The 6600M is better for “epic 1080p gaming.” Keep an eye out for independent reviews of these chips in the coming weeks for better idea of the performance you can expect from each one. The 6000M series will be available starting on June 1st. Radeon RX 6000M series GPU Power target Compute units / ray accelerators Game clock (MHz) Memory (GDDR6) Infinity cache Radeon RX 6800M 145W and above 40 2300 12GB 96MB Radeon RX 6700M Up to 135W 36 2300 10GB 80MB Radeon RX 6600M Up to 100W 28 2177 8GB 32MB AMD also announced AMD Advantage, a new “design framework initiative” meant to encourage OEMs to include certain features on their AMD-powered systems, and to indicate to consumers which Ryzen- and Radeon-powered laptops AMD thinks are the best. It appears to be a similar idea to Intel’s Evo program, but it’s just for gaming laptops, and the standards look much more stringent. It AMD Advantage laptops are expected to include the following: AMD Ryzen 5000 mobile processors, Radeon 6000 graphics and Radeon software Support for AMD’s Smart Acess Memory and Smart Shift technology A display that reaches at least 300 nits of brightness, covers either 100 percent of the sRGB gamut or 72 percent of the NTSC gamut, has at least a 144Hz refresh rate and low latency, and supports AMD Freesync At least one NVME PCIE Express Gen 3 SSD The ability to maintain a surface temperature under 40 degrees Celsius on the WASD keys Over 10 hours of video playback on battery It’s unclear how many laptops will actually meet all of these standards. Forty degrees Celsius is close to as hot as keyboards commonly get in the center. But there aren’t too many gaming rigs that reliably break 10 hours of video playback on battery, and plenty of the best gaming laptops out there max out below 300 nits of brightness. That said, all kinds of Intel Evo-certified laptops also don’t meet all the Evo requirements in my testing — units and methodologies can vary. The first AMD Advantage laptop to be announced is Asus’ new ROG Strix G15. This can be configured with up to a Ryzen 9 5900Hx, a Radeon RX 6800M, and a 15-inch WQHD 165Hz display with 3ms response time. The G15 will be available at Best Buy in June.

  9. AMD triples Zen 3 CPU cache using 3D stacking technology Not a pipe dream—CEO Lisa Su demonstrated a working 3D-stacked 5900X prototype. This exploded diagram shows an additional 64MiB of L3 cache atop the center of the CCD, with structural silicon inserts to either side of the new layer. AMD teased X3D packaging in its Financial Analyst Day a few months ago, but the technology has reached production status much more quickly than expected. AMD CEO Lisa Su holds up a delidded, 3D-stacked Ryzen 5900x processor on stage at Computex 2021. Yesterday at Computex 2021, AMD CEO Lisa Su showed off the company's next big performance play—3D stacked chiplets, allowing the company to triple the amount of L3 cache on its flagship Zen 3 CPUs. The technology is just what it sounds like—a layer of SRAM cache sitting atop the Complex Core Die (CCD) of the CPU itself. Current Zen 3 architecture integrates 32MiB of L3 cache per eight-core chiplet—making 64MiB total for a 12- or 16-core chiplet like the Ryzen 9 5900X or 5950X. The new technology adds an additional 64MiB L3 cache on top of each chiplet's CCD, bonded with through-silicon vias (TSVs). The additional 64MiB L3 cache layer does not extend the width of the CCD, resulting in a need for structural silicon to balance pressure from the CPU cooling system. Compute and cache dies are both thinned in the new design, allowing it to share substrate and heat spreader technology with current Ryzen 5000 processors. Gaming workloads benefit especially from additional L3 cache, as demonstrated by the 12% uplift going from 64MiB to 192MiB in this side-by-side demo. Su claimed 15% average gaming performance uplift for the new technology. Tripling the L3 cache on Ryzen 5000 allows performance gains under some workloads—particularly archive compression/decompression and gaming—similar to those seen with entire new CPU generations. AMD demonstrated performance uplift via a Gears of War 5 demo. Paired with an unspecified GPU and with clock speed fixed at 4 GHz, a current-model 5900X system achieved 184 fps—while the triple-cached prototype managed 206 fps, a gain of roughly 12 percent. AMD claims an average of 15 percent improved gaming performance with the new technology, ranging from a low of 4 percent for League of Legends to a high of 25 percent for Monster Hunter: World. This performance improvement requires neither smaller process node nor increased clock speed—which is especially interesting, in an era where clock speeds have largely hit a wall, and a physics-determined end to process-node shrink seems to be on the horizon as well. Anandtech's Ian Cutress notes that AMD's new 3D chiplet stacking process is clearly TSMC's SoIC Chip-on-Wafer technology in action. While AMD is—at least so far—limiting itself to two layers, TSMC has demonstrated a full 12 layers in action. The problem here is thermal—adding RAM is a near-ideal use of the technology, since the additional silicon doesn't generate much in the way of additional heat. Stacking CPU on CPU would be far more problematic. AMD states that the redesigned 5900X will enter production later this year—well before Zen 4's scheduled launch in 2022. For now, AMD is focusing on the new technology for "high-end Ryzen" CPUs only—no mention was made of Epyc, and the additional silicon required for the added cache makes it a likely nonstarter for budget processors, given current materials shortages.

  10. AMD 3D Chiplet technology: meet the future of processors Movin' on up (Image credit: AMD) AMD made some news last night during its Computex 2021 keynote address when AMD CEO Dr. Lisa Su showed off the company's new 3D chiplet technology, developed in partnership with TSMC. The long and short of it is that rather than spread itself out over a wider die, CPU components like the logic unit and cache memory are stacked on top of each other, utilizing vertical space rather than growing the total surface area of the chip in a flat wafer. While the technology is primarily being pioneered by TSMC, AMD looks to be the first chipmaker to take advantage of the new process by introducing new "vertical L3 cache" to its Ryzen series processors. Without getting bogged down too much in computer system architecture, cache memory is the part of the processor that stores the most relevant data and program instructions for the processor at any given time. The larger the cache, the more data can be stored there so the processor doesn't have to fetch new data from RAM, which takes longer and slows down performance. According to Su, by stacking a 64MB SRAM node onto the CCD (the part of the processor that contains a collection of processing cores), AMD is able to triple the available L3 cache on a 16-core processor from a maximum of 64MB to 192MB. This change alone gave AMD's prototype, a Ryzen 9 5900X processor using the new 3D v-cache tech, a roughly 12% performance boost during a demo of Gear of War 5. This kind of performance increase is typically what you see between processor generations, so boosting the performance of an existing processor by 12% using just a 3D chiplet design is pretty impressive. And while this technology hasn't made its way into a consumer processor yet, AMD says that it "is on-track to begin production on future high-end computing products with 3D chiplets by the end of this year." Are AMD's 3D chiplets the future of processors? Without getting too deep in the weeds of Moore's Law, the writing has been on the wall for the assumption that our computers would get progressively faster for more than a decade now. We can no longer rely on the brute-force engineering of smaller and smaller transistors to make our computers more and more powerful. We are approaching the literal physical limit of how small these transistors can be before individual silicon atoms start becoming unreliable mediums for electrical current. So while we've pretty come to the end of the easy way to fabricate increasingly powerful computers, this doesn't mean the end of progress as we know it. We'll continue to shrink transistors for years to come, but the next phase is moving beyond the transistor and innovating new processor technology that we haven't even considered yet – and 3D fabrication is the obvious next step. We've long realized that when you run out of physical space and you need to squeeze in more of something, whether that means transistors, inventory, or even people, start moving upward rather than outward. All you need to do is look at a city skyline or an IKEA warehouse to see this in practice. AMD's new 3D V-Cache is just the first implementation of many to move in this direction – literally. Expanding the cache available for existing processor architecture is already giving a serious boost to performance, but there's no reason why we can't just start stacking cores as well. This would require all kinds of new engineering solutions to heat management, physical integrity, power consumption, and the like, but those have always been obstacles in processor innovation – and unlike shrinking transistors to the point where you can literally count the number of atoms you're working with, these latter challenges are much more manageable and hold a lot more promise than trying to somehow fab less-than-1nm dies.

  11. AMD finally takes on DLSS with FidelityFX Super Resolution It's been a long wait for an Nvidia DLSS competitor - will it be worth it? After around a year of teasing that it's coming, AMD has finally confirmed that its FidelityFX Super Resolution tech is coming on June 22. AMD made the announcement as part of its Computex 2021 keynote, and it looks to deliver a similar performance boost to Nvidia's DLSS (deep learning super sampling) technology. However, unlike Nvidia's upscaling tech, FidelityFX Super Resolution will work on any recent graphics card, as AMD has demonstrated the tech working on an Nvidia GeForce GTX 1060 in GodFall. AMD FidelityFX Super Resolution, based on Team Red's own claims, should provide a up to a whopping 2x performance jump on AMD graphics cards using the Quality mode of Super Resolution, and up to a 2x performance boost in its Performance mode. These numbers come from GodFall at 4K with ray tracing on an AMD Radeon RX 6800 XT, so it's not clear if these numbers will change at all on other graphics cards. AMD does share some brief information about the technology working with its competitor's graphics cards, but not the same breakdown we see for the 6800 XT. Also in Godfall, but at 1440p, AMD claims that the Nvidia GeForce GTX 1060 can go from 27 fps to 38 fps at 1440p, using the Epic Preset and FidelityFX Super Resolution with its Quality mode. That's not the same 2x performance jump that AMD's own card boasts, but that's still a 41% performance jump. We'll have to see for ourselves how this technology fares once we can get our hands on it for some more in-depth testing on June 22. But for right now, just based on AMD's own claims, this technology is looking extremely promising. AMD finally takes on DLSS with FidelityFX Super Resolution

  13. Two attacks disclosed against AMD’s SEV virtual machine protection system Chipmaker AMD has issued guidance this week for two attacks against its SEV (Secure Encrypted Virtualization) technology that protects virtual machines from rogue operating systems. The two attacks, documented in two academic papers, can allow a threat actor to inject malicious code inside SEV-encrypted virtual machines, giving them full control over the VM’s operating system. Paper CVE SEVerity: Code Injection Attacks against Encrypted Virtual Machines CVE-2020-12967 undeSErVed trust: Exploiting Permutation-Agnostic Remote Attestation CVE-2021-26311 The two attacks, SEVurity and undeSErVed, work not only against AMD CPUs protected by SEV but also SEV-ES (Secure Encrypted Virtualization-Encrypted State), an improved version of the technology that AMD released in 2017, a year after adding SEV to its CPUs. AMD says EPYC CPU line is impacted In a security bulletin released on Patch Tuesday, AMD confirmed the two attacks for the first time. The company said that all AMD EPYC processors are impacted by these attacks. This includes 1st, 2nd, 3rd generation, and embedded EPYC processors, a CPU line typically used in data center servers. The chipmaker said that companies who use AMD CPUs to host virtualized environments for employees/customers should activate SEV-SNP (Secure Encrypted Virtualization-Secure Nested Paging), its latest version of the SEV technology, which it launched in 2020 [see PDF]. “The mitigation requires the use of SEV-SNP, which is only supported on 3rd Gen AMD EPYC,” the company said. Since prior generations of EPYC processors do not support SEV-SNP, the chipmaker advised customers to follow security best practices and avoid a compromise of the host OS, the operating system that runs the SEV-protected VM. The chipmaker released its security advisory this week because the two attacks and their research papers are scheduled to be presented at the WOOT ’21 security conference at the end of this month; when they’re likely to gain more attention from the general public. Extremely happy about that our work on code injection attacks against encrypted VMs, "SEVerity: Code Injection Attacks against Encrypted Virtual Machines" has made it to #WOOT21! w/ Mathias Morbitzer, @martin_b_radev, Erick Quintanar, and Marko Dorfhuber — Sergej Proskurin (@proskurinserg) March 1, 2021 I am very happy to finally lift the curtain on our paper "undeSErVed trust: Exploiting Permutation-Agnostic Remote Attestation" that will appear at @wootsecurity. Thanks @JanWichelmann, Florian Sieck and @tomcrypt for the great collaboration.https://t.co/zWfErNtJ3A — Luca Wilke (@lucawilkeUzL) May 12, 2021 While in the past two years most CPU attacks have primarily targeted Intel CPUs, which have a much larger market share, AMD has had to deal with its own set of issues as well. Last month, the chipmaker admitted that its Zen 3 CPUs were vulnerable to Spectre-like attacks via the processor’s PSF feature. In June 2020, the company also admitted that its AMD Accelerated Processing Unit (APU) processors released between 2016 and 2019 were impacted by “SMM Callout” bugs. Academics first broke AMD’s SEV technology in June 2018 with the SEVered attack. The same research team also broke SEV-ES two years later, in April 2020, with the SEVurity attack. Earlier this month, AMD denied that its CPUs were impacted by an attack that bypassed the patches for the original 2018 Spectre attack, detailed in a paper called “I see dead µops: leaking secrets via Intel/AMD micro-op caches” [PDF].

  14. AMD's Radeon RX 6600 Could Have 8GB of Memory The same could also apply to the RX 6600 XT (Image credit: AMD) An ASRock filing to the ECC has indicated that AMD's future RX 6600 and RX 6600XT could be equipped with an 8GB memory configuration. ASRock's ECC filing showcases model name names for ASRock's custom RX 6600 and RX 6600XT graphics cards and will be ready when (maybe if) AMD releases budget-oriented RDNA2 cards. If this is true, then the 8GB configuration could potentially be AMD's second memory configuration for the RX 6600 series. A few months ago, another ASRock ECC filing demonstrated that the RX 6600 XT could be equipped with 12GB of video memory. It wouldn't be surprising to see two memory configurations for the RX 6600XT, as AMD has done multiple memory configurations on its more budget-friendly cards for years, helping make the cards even more affordable for consumers. However, 12GB and 8GB are odd combinations, suggesting perhaps a high-end 6600 XT and a lower spec vanilla 6600. This is the first we've heard of a memory configuration for the RX 6600, and for now, it seems that 8GB is the only memory configuration for this GPU. But don't be surprised if you see rumors of another memory configuration in the future. Hopefully, AMD won't consider going below the 8GB mark on its RX 6600, as we've found out in graphics card tests that modern games are already sucking dry 6GB graphics cards like the RTX 2060 if you want to play at high detail settings. 8GB and higher should give gamers more than enough memory to play modern titles without worrying about VRAM limitations (at least for a couple of years). ASRock has also listed several RX 6700 12GB model names in the ECC listing, which further indicates that AMD's future RX 6700 is most likely to have 12GB of VRAM. We've already heard about this configuration a few months ago, including a 6GB configurationion for the card, but there is no mention of a 6GB card in this ECC listing. Presumably, AMD is dropping the idea of a 6GB configuration for the RX 6700 in light of the recent RTX 3060 12GB launch. Now that Nvidia has raised the bar on how much memory should be put in a mid-range GPU, it would look bad if AMD released a 6GB model of an RX 6700 which would have to compete with the RTX 3060. Unless you're looking at laptops, in which case Nvidia seems content to give the RTX 3050 Ti and RTX 3050 only 4GB of memory. Hopefully, AMD will release an RX 6700 and RX 6600/6600 XT in the near future. With the 12GB and 8GB VRAM configurations listed, this would certainly help bring more competition to Nvidia's RTX 3060, at least on paper. But really, until this technology shortage expires, we doubt anyone will care. In related news, profitability for Ethereum mining on GPUs doubled this past week. <Sigh.> Source: AMD's Radeon RX 6600 Could Have 8GB of Memory
  15. AMD is biting at Intel's server market share with its largest gains in over a decade Intel is still holding the fort in mobile and desktop, but Epyc chips are snapping at Xeon's dominance in the datacentre. (Image credit: AMD) The first few months of 2021 have been absolutely massive for AMD and Intel. According to the latest report from Mercury Research, the first three months of 2021 saw the largest yearly increase in shipments of CPUs in a quarter of a century, and second only to the final moments of 2020 in terms of raw volume. You'd be perhaps surprised to learn that Intel has gained a touch in overall x86 market share in Q1 2021, whereas AMD reportedly lost out. There's only a percentage point in it: a 1% gain for Intel and a 1% loss for AMD, though. Far from major gains in either direction. Mercury Research puts that down to an increase in budget chip shipments for Chipzilla, which tallies with other figures out of the tech giant as of late. But where Intel has gained in mobile processor market share, it loses out marginally in desktop. That's where AMD's Ryzen processors are seemingly crushing it, and despite some difficulty sourcing the top-tier chips, such as the Ryzen 9 5950X and Ryzen 9 5900X, AMD is still managing to make gains within the market predisposed to Intel processors for so long. AMD reported massive revenue in its last earnings call, and a shift to more high-end processors with higher average selling prices in Q1 certainly goes a long way to explaining that. But perhaps the biggest win in AMD's eyes is the 1.8% increase in server market share quarter to quarter, and 3.8 percent year on year. That means its Epyc processors are selling supremely well against Intel's Xeon chips, and the market that AMD will be most determined to get more of a footing in. Datacentres are not quite so fickle as us gaming lot, see. While 1.8% may appear marginal, it equates to a helluva lot of server chips. In fact, since Intel's server sales were down, AMD managed its highest single-quarter market share gain since 2006, back in the Opteron days. Clearly it's a good time to be in the business of chipmaking—what with demand soaring to space and showing few signs of slowing. Sadly, however, it's not been great for us gamers as demand sees stock depleted within moments of returning, and often sold on for profit. At least that's mainly graphics cards, and not all CPUs. It's still possible to pick up some of the best CPUs for gaming going. Source: AMD is biting at Intel's server market share with its largest gains in over a decade
  16. AMD's 21.4.1 driver brings a ton of cool new features but Super Resolution is still missing Today, AMD announced its major driver overhaul that was missed last year possibly due to the pandemic situation. The new WHQL driver is coming in the form of the Radeon Software Adrenalin 21.4.1. Despite a lot of new additions and updates, the driver is missing the most anticipated FidelityFX Super Resolution feature. Fidelity FX Super Resolution is a part of AMD's FidelityFX DirectX 12 Ultimate suite and is said to be a framerate boosting technique similar to Nvidia's DLSS where an image will be rendered at a lower resolution and then upscaled to a higher resolution by using AI and ML techniques. However, AMD fans should not despair as there are rumors that FidelityFX Super Resolution will not come with a separate driver and will in fact be implemented in games separately. With that out of the way let's now talk about the loads of features that it does bring. General improvements and feature additions which now bring minimal installation options: Customized user interface options are now available in the Radeon Software installation to modify the user interface. Options exist for a Full Installation, Minimal Installation and Driver only installation. Vivid Gaming Display Color Enhancement : A new color profile that allows users to enable a more vivid look for their display color. Color Deficiency Correction : A new feature that allows users to adjust their display colors for all three major color deficiency types with strength sliders. Improved search bar functionality. Stats information for games is now available in the games tab. Historical navigation buttons added to easily move back and forth between tabs. Toggle added to enable or disable the built-in web browser. Settings option added to enable or disable all hotkeys in a single click. Updated AMD Link software which enables high-performance remote gaming on Windows PCs in addition to phones, tablets and TVs; new AMD Link Game feature allows another Radeon user to remotely connect to play local multiplayer-supported games. A brand-new AMD Link for Windows client is now available that allows you to stream your games and desktop to other Radeon graphics enabled PCs. New "Link Game" feature that allows you to easily connect with a friend to play games together on a single PC or even help them troubleshoot a PC issue or problem. Redesigned streaming technology for better visuals and lower latency. New quality of service feature that dynamically adjusts your streaming settings based on your internet connection. Now supports up to 4k/144fps streaming. Simplified AMD ReLive user interface and other improvements: Recording and streaming settings have been consolidated into one easy to use tab. A new Streaming Wizard is now available which helps users configure their recording and streaming settings for the first time. A new ‘adaptive’ quality setting is available in the wizard that allows Radeon Software to monitor your stream and make changes to quality based on your stream’s performance. Improved scene editor usability for creating and editing scenes. An option is now available to select which display you would like to record or stream from in multiple display system configurations. Performance Tuning changes: Introduced CPU metrics and monitoring to the performance metrics tab in Radeon Software. Improvements made to the performance metrics tab including design updates to the graphs for metrics, more performance readouts, improved logging controls and improved performance overlay controls and graphs. New AMD Crash Defender feature: Preserves data and keeps your system running in some cases where your system may have otherwise experienced a crash or hang. Microsoft PlayReady AV1 Decode Support, which now means AMD GPUs can decode PlayReady DRM- protected AV1 content. AMD Eyefinity support, which is AMD's Multi-display technology, has now been extended to Ryzen Mobile 4000 and Ryzen Mobile 5000 series APUs. Interestingly, while AMD hasn't mentioned it in its press release, VideoCardz says that the driver also brings support for Radeon Boost with integrated Variable Rate Shading (VSR) in the following games, however, you'd need a Radeon RX 6000 series GPU to enable it: Rise of the Tomb Raider, Shadow of the Tomb Raider, Borderlands 3, Metro Exodus, Fortnite, Cyberpunk 2077, Resident Evil 3, Call of Duty Modern Warfare 2019. Check out AMD's video below to get a gist of the new features. Aside from the new feature additions, the driver also brings a bunch of bug fixes. They are: Brightness flickering may intermittently occur in some games or applications when Radeon™ FreeSync is enabled, and the game is set to use borderless fullscreen. SteamVR™ may experience an application crash when a VR headset is connected on Radeon RX 500 series graphics products. Some high refresh rate, high resolution TV displays may experience corruption when connected via HDMI on Radeon RX 6000 series graphics products. Applying changes in Radeon Performance Tuning may sometimes fail to take effect for changes made to power tuning. Lower than expected performance may be experienced in some CPU intensive workloads or games. Global performance tuning overclock profiles may sometimes override game specific performance tuning profiles or cause game specific performance tuning profiles to fail to load on a games launch. Radeon Chill may experience lower than expected performance when a game is left idle for an extended period with Radeon Chill enabled. Flickering may be observed in Radeon Software performance overlay while playing Cyberpunk 2077™ on Radeon RX 6000 series graphics products. And below is the list of bugs that are yet unresolved: Enhanced Sync may cause a black screen to occur when enabled on some games and system configurations. Any users who may be experiencing issues with Enhanced Sync enabled should disable it as a temporary workaround. Connecting two displays with large differences in resolution/refresh rates may cause flickering on Radeon RX Vega series graphics products. Radeon performance metrics and logging features may intermittently report extremely high and incorrect memory clock values. Cyberpunk 2077™ may experience shadow corruption on Radeon RX 6000 series graphics when ray tracing is enabled. Disco Elysium™ may experience texture flickering on trees with Radeon RX 6000 series graphics products. Radeon Software may experience a crash when Record & Stream tab is in use and a display is hot plugged. Radeon FreeSync™ may intermittently become locked while on desktop after performing task switching between extended and primary displays upon closing a game, causing poor performance or stuttering. A system restart is a potential workaround if this is experienced. Performance metrics may incorrectly report temperatures on Ryzen™ 5 1600 series processors. The download or launch Ryzen Master buttons in Radeon Software may intermittently disappear or may fail to initialize Ryzen Master. If Ryzen Master is not detected in Adrenalin software after installation, a system restart maybe required. There are also a couple of issues with the new Link for Windows: AMD is investigating isolated reports of intermittent loss of signal during Stream Optimization if HEVC is used on Radeon RX 5000 series graphics products or later. A workaround is to use the AVC encoding setting instead. Intermittent grey frame corruption might be observed when streaming with HEVC on certain configurations via an Internet connection. A workaround is to use the AVC encoding setting instead. If you wish to download the Radeon Software Adrenalin Edition 21.4.1 driver, you can do so by visiting the driver's release notes page here where you will find separate download links for Windows 10 and Windows 7 64-bit. As usual, the product is compatible with all GCN and RDNA products (HD 7000 series and newer). You can find more information on the new Radeon Adrenalin 21.4.1 driver here. via VideoCardz Source: AMD's 21.4.1 driver brings a ton of cool new features but Super Resolution is still missing
  17. AMD acknowledges USB connectivity issues on X570 and B550 motherboards If you've experienced problems, AMD wants to hear about them In brief: Reports of USB connectivity issues on AMD X570 and B550 motherboards have circled the forums since the boards’ release, but the issue has recently come to a head on Reddit. AMD has responded with a simple statement: they’re not sure what the issue is, and they’d like to collect more data. For the past few months, reports of sporadic USB disconnections on 500-series motherboards have been stacking up on the desk of AMD’s subreddit. Some users have reported that their keyboard will suddenly become unresponsive for 5 to 10 seconds, every few minutes. Other users complain that their mouse will slow down. Owners of sound cards are talking about crackling and distortion. The strangest thing about the issue is that it seems to be new -- because X570 and B550 boards aren’t. While the first complaints were posted over a year ago, their frequency seems to have increased exponentially in the past month. Some Redditors recently compiled a statistics table for users to share their issues and system specifications, and it looks like the issue is mostly occurring in systems with new RTX GPUs. But don’t worry, a flagship GPU isn’t a necessity. A mid range GPU and a few high bandwidth devices, like external hard drives, external capture devices, or VR headsets and tracking stations seem to do the trick just as well. And it’s not just the high bandwidth device that will experience the issue, anything connected to the same system can be affected, including internally connected devices like CPU coolers -- which is a very serious issue. Some workarounds have been found by the community. The first port of call: turning off "c-states" in the BIOS. It won’t carry a penalty, and it can halve the frequency of disconnects. But if that doesn’t work, your remaining options are to switch from PCIe 4.0 to PCIe 3.0 or to go through the BIOS and disable every USB port/header you’re not using. Doing all three will stop the disconnections for most people, but not for power users. Streamers with a capture card, microphone, webcam, and the usual batch of peripherals are out of luck, basically. That’s where AMD comes in. They’ve asked anyone experiencing issues to report them on AMD’s website. They’ll also be messaging some people who’ve commented on their problems on Reddit. An Update on USB connectivity with 500 Series Chipset Motherboards from r/Amd Hopefully, AMD will be able to resolve these issues quickly with a firmware update. In the meanwhile, for new system builders, our best advice is to opt for an AMD GPU to pair with X570 and B550 motherboards, as the combination seems to be almost devoid of issues.

  19. AMD looks set to reveal surprise RX 6800 XT ‘midnight black’ limited edition GPU Although any graphics card released these days is ‘limited’ in terms of stock (Image credit: Future) An AMD Radeon RX 6800 XT ‘midnight black’ edition graphics card is set to be unleashed later today, according to a new report. VideoCardz was tipped by a reader who is a member of the AMD Red Team, and received an email giving them early warning of the release of the limited edition GPU. Although arguably, any graphics card release these days is a ‘limited edition’, given the thin stock on the ground which get snapped up immediately (from AMD or Nvidia regardless). If the info is correct, the ‘midnight black’ model of the RX 6800 XT runs with exactly the same spec as the vanilla card, the only distinction being the appearance. The AMD email reads: “We have created a select quantity of AMD Radeon RX 6800 XT (Midnight Black) graphics cards featuring the same great performance of the widely popular AMD Radeon RX 6800 XT. “This is an exclusive advance notice to members of the AMD Red Team community and this offer has limited availability, while supplies last.” Imminent release The graphics card supposedly goes on sale directly from AMD.com today at around 6am PST (9am EST, or 2pm UK time), presumably at the same price as the standard RX 6800 XT, or perhaps with a small price bump. Whatever the case, if this is indeed true, there will naturally be a scramble to grab the GPU, and the usual interference from scalpers (and bots) no doubt. So as ever, your odds of actually securing one of these purported graphics cards are likely to be shaky-to-terrible. If you miss out, on this or any other GPU, the best thing you can do is keep your fingers crossed that broader stock availability improves sooner rather than later. You could also keep an eye on our where to buy AMD’s Radeon RX 6800 XT article which is constantly updated with info on the latest stock levels (we have one for the RX 6800 as well).

  21. AMD unveils its third-gen EPYC server CPUs with Zen 3 cores As the company had announced a few days ago, AMD today took the wraps off the third generation of EPYC CPUs, geared towards the server market. These are the first EPYC processors based on the Zen 3 core architecture that debuted with the Ryzen 5000 series, and they promise up to a 19% increase in instructions per clock compared to the previous generation. The lineup includes processors with anywhere from eight to 64 cores, and between 16 and 128 threads, and they include support for things like 4-6-8 channel memory interleaving. AMD is claiming to have the highest performing server CPU - the 64-core EPYC 7763 - as well as the highest performance per core, though that refers to the eight-core EPYC 72F3 in a dual-socket system. AMD shared some performance numbers comparing its lineup to Intel offerings, which show that AMD is ahead in performance in multiple categories, though it's worth noting that the CPUs used in each of the comparisons don't cost the same. For example, the Intel Xeon Gold 6258R costs $3,950 (based on thousand-unit purchases) compared to the $4,860 for the AMD EPYC 75F3 used in the fourth comparison. Here's the full lineup of EPYC 7003 processors: AMD highlighted a number of partners, specifically in the cloud market, including Microsoft Azure, Google Cloud, AWS, and Tencent Cloud, which are all planning to start deploying third-generation EPYC processors. You can learn more about EPYC processors on AMD's website. Soruce: AMD unveils its third-gen EPYC server CPUs with Zen 3 cores
  22. AMD Unveils New Security Features With Launch of EPYC 7003 Series Processors Chipmaker AMD on Monday announced the launch of its new EPYC 7003 series server processors — codenamed Milan — and the company has shared some information about new and improved security features. The new CPUs are based on the Zen 3 architecture and AMD says they bring significantly improved performance for enterprise, cloud and HPC workloads. The EPYC 7003 series processors are available immediately — device manufacturers have started announcing new products that use them, and major cloud providers will use servers powered by these CPUs. According to AMD, its 3rd Gen EPYC processors include several new or enhanced security features, including a dedicated security subsystem, hardware-validated secure boot, hardware root of trust, Secure Memory Encryption (SME), Secure Encrypted Virtualization-Encrypted State (SEV-ES), and Secure Nested Paging (SNP). One important new feature is SNP, which provides enhanced memory protections to prevent malicious hypervisors from conducting replay, corruption or remapping attacks. Specifically, SNP adds memory integrity protection capabilities designed to prevent hypervisor attacks by creating an isolated execution environment. In the case of SEV-ES, which provides a layer of protection for CPU registers, AMD has added interrupt restrictions that should prevent malicious hypervisors from injecting interrupts and attacking ES guests. Other security features present in the new processors include memory protection keys for users, and Shadow Stack, a new feature that helps protect against ROP (return-oriented programming) attacks. AMD also noted during a briefing ahead of the launch of its new product that with the 3rd Gen EPYC processors they have been able to implement better mitigations against Spectre attacks.

  24. AMD announces $479 Radeon RX 6700 XT, says it will have ‘significantly more GPUs available’ ‘We know it’s crazy out there, we’re doing everything we can’ AMD has heard you loud and clear: you can’t buy its excellent RX 6800 and 6800 XT graphics cards at anything close to their retail prices. Today, the company’s announcing a new GPU that might (but probably won’t?) change that: the Radeon RX 6700 XT. “With the AMD Radeon RX 6700 XT launch, we are on track to have significantly more GPUs available for sale at launch,” AMD tells The Verge. Even better: AMD claims it’ll begin refreshing stock of RX 6000 GPUs and Ryzen 5000 CPUs every week on its own website, where it’ll sell them at their retail prices. We’ve been waiting for that for nearly two months. The new RX 6700 XT will arrive on March 18th for a suggested retail price of $479. In a normal, sane year, that would slot it between Nvidia’s $500 RTX 3070, which we called “the 1440p sweet spot,” and Nvidia’s bang-for-the-buck $400 RTX 3060 Ti, where you might have to dial down the settings here and there. It’s also a full $100 less than AMD’s $579 RX 6800, which we found had enough oomph for entry-level 4K gaming. This isn’t a sane period for GPU buyers, though. In December, the actual street prices of the $400 3060 Ti, the $500 3070, and the $579 RX 6800 were $675, $819, and $841, respectively — and that was before Trump’s tariffs pushed Nvidia and AMD’s board partners to raise their retail prices. “We know it’s crazy out there, we’re doing everything we can,” says AMD’s Nish Neelalojanan, a director of product management. That not only includes more stock at AMD.com but also additional supply for board partners and manufacturers that’ll sell gaming PCs later on. AMD wouldn’t say how much of that stock is being allocated toward GPUs that’ll be sold at AMD.com, though. It says it doesn’t set its partners’ retail prices either. Assuming for a moment that AMD pulls it off, managing substantially greater availability than Nvidia’s recent debut, the RX 6700 XT sounds like it could be a compelling pick. With 230 watts of power, 12GB of video memory, and 40 compute units (compared to 60 for the RX 6800 and 80 for the RX 6800 XT), AMD’s promising you’ll be able to play all of the latest games at maximum settings at 1440p resolution. With a fast enough CPU, AMD suggests you should be able to hit 212 fps in Overwatch, 272 fps in League of Legends, and 360 fps in Rainbow Six Siege, enough for esports gamers to justify some of the fastest monitors on the market. AMD says it should be fast enough for ray tracing at 1440p as well. The company’s early benchmarks (see above) show it pulling ahead of Nvidia’s 3070 and 3060 Ti, though not in all games. It’s worth noting these numbers were generated using the frame rate boost of AMD’s Smart Access Memory (generically known as Resizable BAR), something that’s only just starting to roll out to Nvidia’s graphics cards and generally requires newer CPUs to work. That said, AMD also just announced that it will begin rolling out Resizable BAR to its Ryzen 3000-series processors, not just the newer Ryzen 5000 ones. The new card will require two power connectors, an 8-pin and a 6-pin, and the GPU should be clocked somewhat faster than in earlier RX 6000-series cards at up to 2424MHz. It’s got a 192-bit memory bus, down from 256-bit for the company’s other 6000-series cards. Clearly, we’ll have to test the RX 6700 XT’s performance ourselves, but nothing matters more than availability — and where that availability will leave the card’s actual price by the time you can buy one. AMD claims cards will be available on March 18th from all of the usual board partners, 40 different system builders, and AMD.com, with prebuilt systems including the HP Omen 25L and 30L desktops coming later this spring and beyond. While AMD’s own version is a dual-fan card with the same basic reference design as the RX 6800 and 6800 XT, it appears many of AMD’s partners are opting for three-fan designs. Those generally carry a premium price as well. And in case you’re wondering, AMD has no plans to nerf the crypto mining performance of the RX 6700 XT the way Nvidia did for Ethereum with the RTX 3060. “We have no plans to limit the product in that way,” AMD told journalists this week. You can watch the company’s 20-minute presentation, including a tease of Resident Evil Village with ray tracing, in the video below. Update, 11:36AM ET: Added that the HP Omen and other prebuilts will arrive later this spring. AMD announces $479 Radeon RX 6700 XT, says it will have ‘significantly more GPUs available’
  25. AMD is announcing a new Radeon RX 6000 GPU in March The event will be held on March 3rd AMD’s Radeon RX 6800 XT GPU Photo by Tom Warren / The Verge AMD has announced a new hardware event for next month, where the company plans to unveil the next GPU in its Radeon RX 6000 line of cards. The presentation will air on March 3rd at 8AM PT / 11AM ET. Like other GPUs in the RX 6000 series, this new model will use the RDNA 2 architecture, including real-time, hardware-accelerated ray tracing and variable rate shading. AMD’s announcement of a new GPU presentation comes just one day before sales kick off for Nvidia’s affordable RTX 3060 GPU at select retailers. AMD debuted the Radeon RX 6000 line of graphics cards in late October, with the GPUs serving as a direct competitor to Nvidia’s RTX 30 cards. Currently, the RX 6000 consists of three GPUs: the flagship RX 6900 XT, the $649 RX 6800 XT, and the RX 6800, which is the most affordable of the trio at $579. With the announcement of a new RX 6000 card coming, we anticipate that, like other GPUs in this series, it will sell out quickly. In January, AMD told The Verge that within the first quarter of 2021, it expects to sell more of its own RX 6000 cards through its website, which is bittersweet news considering the RX 6000 has been difficult to buy.
