| JEMC said: From my understanding, Intel owns x86 instruction set, and anyone that wants to make an x86 CPU needs to get a license from them. AMD developed the x64 extensions that Intel uses them thanks to the cross-patent agreements that both companies have. I don't know the situation regarding newer instructions/extensions. |
Nope. x86 is an (loosely defined) instruction set, not an IP, and one that is public and throughly documented.
It's just that it would be almost useless for anyone else to build a x86 CPU with 2005 paradigms, which is how long behind one would be based on expired Intel/AMD patents.
