Earlier quoted context omitted.
AFAIK Intel and AMD cross-license everything. And its not that tech runs just from Intel to AMD. x64 is AMD tech that got adopted by Intel. Monolith multi-core technology is also something Intel adopted from AMD. Intel wouldn't dare destroying AMD. Since AMD got created for sole reason to prevent Intel from being torn apart. But Intel will do everything to keep AMD's market share somewhere comfortably below 20%.
And what about ARM and Apple chips (like the A4)?
Is Intel supposed to just implement it for them or something?
Or are they supposed to get to their own terms with them studios?
