Intel's Boyd Phelps has confirmed that 8-core Tiger Lake processors with up to 24 MB of low-level cache are in the offing soon. Rumors indicate that Tiger Lake-H will be available in 35 W and 45 W variants with four cores and up to eight cores, respectively. It will be interesting to see how the competition between Tiger Lake and AMD's upcoming Cezanne mobile APUs pans out.

Intel recently announced the Willow Cove-based Tiger Lake lineup for thin and light laptops, and it was only natural to speculate that the architecture would eventually expand beyond four cores. Looks like we will get to see 8-core Willow Cove processors soon, according to a blog post by Boyd Phelps, Intel's CVP of Client Computing Group, on Medium.

Boyd's post mainly deals with the advantages that the new Tiger Lake platform offers in terms of architecture, graphics, power efficiency, memory, and the likes. In the midst of it all, he confirms that an 8-core product is in the works. He writes,

The Willow Cove core increases the mid-level cache to 1.25MB — up from 512KB. We also added a 3MB non-inclusive last-level-cache (LLC) per core slice. A single core workload has access to 12MB of LLC in the 4-core die or up to 24MB in the 8-core die configuration (more detail on 8-core products at a later date)".

A H-series processor means a TDP between 35 W to 45 W and information to that effect has been discovered by known leaker Sharkbay on the PTT Shopping forums. According to Sharkbay, the following Tiger Lake core and iGPU configurations can be expected:

Tiger Lake variantSocketTDPCore configurationXe LP EUs
TGL-UP3BGA144915 W to 28 W2C, 4C96
TGL-H35BGA144935 W4C96
TGL-HBGA178745 W4C, 6C, 8C32

Tiger Lake-H will apparently be available in both 35 W and 45 W variants with the former topping out at four cores and the latter up to eight cores. It is interesting to see Tiger Lake-H offering only 32 EUs of Iris Xe LP integrated graphics. This could be because most of the H-series notebooks usually come with some sort of discrete graphics options. By the time Tiger Lake-H is official, we may get to see NVIDIA Ampere and AMD RDNA2 mobile variants that would complement this CPU. Another possibility is that Intel could be offering its own 96 EU Xe as a dGPU variant, the DG1.

From early benchmarks, it was evident that Intel has finally managed to keep pace with AMD's Renoir Ryzen 4000 at least in a few tests. The introduction of 8-core parts for gaming and content creation laptops will see Intel fighting it out with the likes of the AMD Ryzen 7 4800H and the Ryzen 9 4900H. Of course, AMD will not be resting on their laurels and we can expect Zen 3 Cezanne to counter both Tiger Lake-U and H-series quite handsomely.

I am a cell and molecular biologist and computers have been an integral part of my life ever since I laid my hands on my first PC which was based on an Intel Celeron 266 MHz processor, 16 MB RAM and a modest 2 GB hard disk. Since then, I’ve seen my passion for technology evolve with the times. From traditional floppy based storage and running DOS commands for every other task, to the connected cloud and shared social experiences we take for granted today, I consider myself fortunate to have witnessed a sea change in the technology landscape. I honestly feel that the best is yet to come, when things like AI and cloud computing mature further. When I am not out finding the next big cure for cancer, I read and write about a lot of technology related stuff or go about ripping and re-assembling PCs and laptops.
