Key Intel Core i9-11980HK, Core i7-11800H, and Core i5-11400H specifications surface online via leaked press deck

We've come across quite a few of Intel's Tiger Lake-H CPUs in the past few weeks. It showed up alongside the Intel NUC 11 Extreme and a rugged workstation. The mobile processors aren't due to arrive until Q2 of this year, but we now have a good idea about what they could have in store for us thanks to Twitter user @9550pro, who managed to get a hold of the Intel Tiger Lake-H spec sheet.

Starting with the top-of-the-line Intel Core i9-11980HK, we get an 8C/16T CPU with a base clock of 2.6GHz and a boost clock of up to 5.0GHz on a single core. It has a cTDP (up) of 65W. This information sits in line with a report from earlier, which detailed the processor's AVX-512 performance. While the base and boost clocks are a tad lower compared to the previous-generation Intel Core i9-10980HK (5.3GHz), there are several improvements, across the board, such as a higher L3 cache (24MB vs 16MB), better GPU, faster RAM and newer 10nm process node.

The Intel Core i9-11900H, bumps down the base and boost clocks to 2.5GHz and 4.4GHz, respectively. Its single and dual-core boost clocks max out at 4.9GHz. Its 35W cTDP (down) is somewhat understandable, given the significantly lower 2.1GHz clock speed.

Moving on to the Intel Core i7-11800H, we get the same eight-core, sixteen-thread configuration, but with a reduced base (2.4GHz) and boost (4.2GHz) clocks. The SKU does not come with Intel's Turbo Boost Max 3.0 technology, thereby reducing its maximum single and dual-core boost values to 4.6GHz. It has the same cTDP of 35W (down) with a rated clock speed of 2.0GHz. All three processors (Core i9-11900HK, Core i9-11900H, and Core i7-11800H) have a rated TDP of 45W and support 3,200MHz DDR4 RAM.

That leaves us with the Intel Core i5-11400H, which is a six-core, twelve thread processor clocked at 2.7GHz (base) and 4.1GHz (all-core boost). The processor supports up to 2,933MHz DDR4 RAM. All four CPUs will run Intel UHD iGPUs with clocks ranging between 350MHz and 1,450MHz but neglects to specify the exact model. A Geekbench listing from earlier showed an Intel Core i7-11800H running alongside the Intel UHD Graphics Xe 750 variant with 32EUs.

If previous releases are anything to go by, we can expect a few more Tiger Lake-H SKUs to show up online soon. There were a total of twelve Comet Lake-H processors, including mobile Xeon W chips. However, the number of Tiger Lake-H CPUs could be a lot more scarce, given that Alder Lake is due to be launched in September 2021. Many enthusiasts wouldn't mind skipping Tiger Lake-H entirely to see Alder Lake's hybrid CPU architecture in action.
