The first Comet Lake-H based laptops are expected in February, with broader availability in Spring 2020.
Two leaked parts showed up in in the Geekbench database, the Intel Core i5-10300H and Core i7-10750H. The former has a boost clock around 4.4-4.5 GHz while the latter has a 4.95-5.00GHz Boost.
Intel also teased Tiger Lake, the successor of Ice Lake. Tiger Lake will have DL (deep learning) Boost, Xe based integrated graphics, and low power accelerators. This processor may feature the Xe-LP microarchitecture, it will reportedly have 96 execution units, the same number that's rumored for the "DG1", the first Xe-based discrete video card.
Tiger Lake is believed to be made on 10nm++ and Legit Reviews writes the chip will feature various enhancements for AI:
From a deep learning boost (DL Boost) standpoint we were told that you’re gonna see a lot more AI performance on Tiger Lake. When you get to the Intel Xe graphics, we learned that the INT8 instruction set has been accelerated for on Xe Graphics for faster inferencing performance for AI with Xe graphics on Tiger lake. And then on the Intel GNA for low-power neural network acceleration side they are moving on to GNA 2.0. This bring a whole generation improvement with regards to low power acceleration. So, all three AI engines that Intel currently leads the industry with on Ice Lake processor will all be updated and refreshed for the Tiger Lake processor series.Source: VideoCardz
