Opinion | Comet Lake-H will be another 14 nm refresh, not a move to 10 nm, and here's why

Talk about Intel Comet Lake-H, and confirmation of certain SKUs arriving by the end of March, has prompted speculation about what dies Intel will use for the successors to the Coffee Lake-H Refresh architecture. While some have speculated that Comet Lake-H will mark a move to Intel's 10 nm process, all signs point to it being another 14 nm refresh.
Alex Alderson,

Intel has been on its 14 nm process for years, as we covered in our Core i5-10300H article earlier this week. In short, Intel moved its H-series onto 14 nm nodes in 2015, with generational changes becoming increasingly minor in the last few years. However, there appears to be some confusion about what Comet Lake-H represents.

As part of the coverage of Comet Lake-H, some outlets have opined that Intel will base Comet Lake-H on its Sunny Cove architecture, which would mean a switch to 10 nm for the company's new H-series processors. This speculation seems to be predicated on the notion that Intel's 14 nm foundries are overloaded, and that it would be a good move to combat AMD's 7 nm Renoir series.

However, there appears to be no evidence that this is the case. On the contrary, all roads currently lead to Comet Lake-H being another 14 nm refresh. Firstly, an alleged Intel roadmap shows that the company does not plan to bring 10 nm to the H-series before the end of 2021. While it is easy to cast this aside as another leak, it accurately predicted the arrival of Comet Lake-H.

The minor performance improvement that Laptopmedia demonstrated between the Core i5-9300H and Core i5-10300H underlines this, too. Recent Geekbench listings have demonstrated that the Core i5-10300H carries the same "GenuineIntel Family 6 Model 165 Stepping 2" identifier as the Core i7-10750H and Core i9-10980HK do. Hence, there appears to be no evidence of Intel splitting Comet Lake-H between 14 nm and 10 nm nodes.

In short, Comet Lake-H is probably 14 nm+++, just as Comet Lake-U is. While we are not ruling out the possibility of Intel surprising everyone with 10 nm Comet Lake-H chips, the likelihood of that seems incredibly slim.
