What is Intel doing? A 12W CPU should not be faster than their 125W flagship. Single core performance is what matters the most in a lot of usage scenarios.
Intel is still on 10nm lithography. Did they stop investing in R&D and machinery a while back? AMD is on 7, Apple on 3.
Intel literally spent a decade trying to make there CPUs just a little bit faster, but not too much faster, every year. They succeeded in doing so, and we have this as a result.
The worst part is they aren't eving running at 125w or whatever they claim, often into the 180w or 200w range to reach there own marketing benchmarks.
