The only ARM IP Apple actually used was the ISA. The architecture in the M1 -- and all the A chips -- is 100% custom.
No other gadget maker has the internal engineering chops to do what Apple has done. And it'll be a few years before ARM releases a chip architecture that comes within spitting distance of the M1's performance -- by which time Apple will have released an even more powerful chip.
