Traditionally Intel's "nm" measurements have always deviated a bit from their competitors, ala TSMC and Samsung. In short Intel 10nm ~ TSMC 7nm and Intel 7nm ~ TSMC 5nm. But with the recent announcement that the 7nm will be delayed, it means TSMC will for sure take the node crown. https://en.wikichip.org/wiki/7_nm_lithography_process

I think the most notable is part is that Tiger Lake will be a minimal CPU improvement (Sunny Cove ~ Willow Cove cores), and the main selling point will be the Xe graphics and support for Thunderbolt 4, LPDDR5, etc. Superfin seems to be marketing hype but will see when benchmarks come out.

The main question is, will Tiger Lake will enough for next year? AMD's Renoir follow up is reportedly retaining the Vega graphics but will further improve the CPU microarchitecture from Zen2 to Zen3. Techspot just published an apples-to-apples comparison that shows, if all things equal except the CPU, the AMD 4800H is 10-60% faster than the i7 10750H...that's a huge chasm. https://www.techspot.com/review/2075-same-laptop-different-c...
