Intel’s 8-Core Mobile Tiger Lake-H, at 45 W, to Ship in Q1


Recommended Posts

Ever since the launch of Intel’s 11th Gen Core mobile processors, known as Tiger Lake, back in September, the chips' limited core counts have not gone unnoticed. At a time where its competition is leveraging 8 cores in the same space, Intel seems limited to only 4 in the same 15-28 W power window. At the time, Intel stated that the base Tiger Lake design was aimed to be scalable, and that double sized variants were in the works. Today Intel has confirmed that those double-sized parts will be coming in Q1, in the form of Tiger Lake-H.


Back at Intel’s Architecture Day 2020, lead architect Boyd Philips stated that even though the standard Tiger Lake UP3 design contained four cores and 12 MB of L3 cache, designs with double the L3 cache were in the works. This was instantly interpreted that double core-count versions of Tiger Lake were in the works, given that in the last generation the higher-powered mobile processor line-up had been left to older 14nm processors to fill the gap, and that Intel normally launches products for both 15 W and 45 W at the same time. We had been expecting a fast follow on, with a launch sometime later in Q3'20, but it would appear that Intel has pushed this out to Q1'21. Intel says that these processors will start production and ship in Q1, which likely means that the actual products will come to market in Q2.




Intel has confirmed that these parts will offer up to eight cores and sixteen threads, with a highlight being that the top variants will enable 5.0 GHz turbo frequencies on multiple cores. These processors will also have 20 lanes of PCIe 4.0, which will allow for a full PCIe 4.0 x16 link to a discrete graphics card and a single PCIe 4.0 x4 storage drive at the same time, while also having a separate link for the chipset and IO. We expect these processors to also support PCIe Resizable BAR.


And, like their current quad core counterparts, these processors will also have Thunderbolt 4 native support, as well as Wi-Fi 6/6E support through an associated RF module.  


Intel traditionally has a number of overclockable H-series processors, known as HK, however the company has not explicitly stated if any overclocking SKU will make it to market. Typically these H-Series processors target the 45 W market, with a 35 W step-down option. Intel is also announcing today that it has moved its U-series processors, typically 15 W, up into that 35 W market as well (known as H35). We will start to see some overlap between the two, with higher frequency quad-core U-series processors up against eight-core H-series parts.


We wait to see exactly what specifications Intel will target with the new hardware. More detail to come.

Today at CES 2021, Intel is making a wide range of announcements. Alongside its Tiger Lake vPro processors, it's also announcing new Tiger Lake chips for gaming PCs. This is called Tiger Lake-H35, because these are 35W processors instead of the typical 45W TDP that we usually see in H-series mobile CPUs. It's built on a 10nm process, a first for anything beyond the U-series or Y-series, and that's presumably part of the reason that the TDP is turned down. Don't worry though; you can still get turbo speeds of up to 5GHz.


But Intel is creating a new category out of it. Typically, you'll find H-series processors in gaming laptops and mobile workstations, so now, you're going to start to see ultraportable gaming laptops. They're going to be 18mm thin, while existing thin gaming laptops tend to be 20mm. It's aimed at 1080p gaming, and of course, you'll still get next-gen graphics with PCIe 4.0.




Along with the 35W TDP and 10nm process, these chips are quad-core with eight threads. Intel says that the Core i7-11375H has the fastest single-threaded performance of any laptop chip, matched only by the 45W Core i9-10980HK, and it outperforms competitors by 30%. Of course, we're only comparing single-core performance, since competitors are using more cores.


In fact, Intel's own mobile processors have more cores than that, which is why the SKU is a relatively low number for a Core i7. The full 45W mobile processors are coming, and you'll see eight-core CPUs with 16 threads and up to 5GHz clock speeds soon enough. Intel also said the new chips will support Thunderbolt 4, Wi-Fi 6/6E, and PCIe Gen 4 with 20 lanes.
