intel is competing on 10nm (now called intel 7) against TMSC's 7nm process. >If Intel has massively more efficient chip designs that they plan to use in mobile, why aren't they making use of them? They could have competitive performance without doubling the power consumption. I'd guess they're aimed at making competitive enthusiast class desktop chips with their existing process size from foundries they already have made many many chips from so there's much less investment, and saving any smaller process capacity for laptops chips.
