If x86-64 is "open" why are Intel and AMD the only manufacturers..? The answer: it isn't open, it's proprietary. Check out x86 history, it's kinda interesting.

- userbinator 5y agowhy are Intel and AMD the only manufacturers x86-64 is patented (and the earliest CPUs with it are now over 20 years old, so probably expiring soon if not already), but original 32-bit x86 is long out of patent and there are/were quite a few other manufacturers. https://en.wikipedia.org/wiki/List_of_x86_manufacturers https://en.wikipedia.org/wiki/List_of_x86_manufacturers https://en.wikipedia.org/wiki/List_of_former_IA-32_compatible_processor_manufacturers https://en.wikipedia.org/wiki/List_of_former_IA-32_compatibl... https://en.wikipedia.org/wiki/Vortex86 https://en.wikipedia.org/wiki/Vortex86
