A bug or whatever in their 13’th and 14’th gen CPU’s makes them slowly but permanently degrade and cause crashes. Intel have not been handling the issue as you would hope since the discovery. Denying, downplaying, refusing a recall, refusing extended warranties, the lot. Now the lawsuits are cooking.
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.
