The x86 companies (and/intel) do better with competition.
I’ve had my last laptops (work/home) with amd and it’s much better battery life and performance then my (9th? Gen) intel notebook with nvidia (the battery life was Terrible but it could game). I think Apple puts a lot of pressure on too, which helps.
I guess intels “ultra” notebook parts are better.
There is some x86 advisory group now to keep the instruction set in sync between the 2 companies. Linux is involved and is Linus so it should be at least a little fun.
