That’s a wee revisionist: Zen/Zen+/Zen2 were not especially performant and Intel still ran circles around them with Coffee Lake chips, though in fairness that was probably because Zen forced them to stuff more cores on them.
Zen3 and newer, though, yeah, Intel has been firmly in 2nd place or 1st place with asterisks.
But the last 18 months has them fucking up in such a way that if you told me that they were doing it on purpose, I wouldn’t really doubt it.
It’s not so much failing to execute well-conceived plans as it was shipping meltingly hot, sub-par performing chips that turned out to self-immolate, combined with also giving up on being their own fab, and THEN torching the relationship with TSMC before you launched your first products they’re fabbing.
You could write the story as a malicious evil CEO wanting to destroy the company and it’d read much the same as what’s actually happening (not that I think Patty G is doing that, mind you) right now.
Sounds good to me?
