CPUs I can imagine that’s true and almost assured but GPU… I dunno about that. It’s up to the companies. It will take a concerted time and effort to support what might be a very niche/limited product. That’s time and money, Intel possibly could consider doing it to get more press and such but unlikely.
Nvidia would be the best shot and yeah it’s not a sure thing, not at all not even by a long shot. Hopefully, they do, and the fact AMD’s partner program doesn’t prohibit this is at least one good mark in our favour.
