Zhaoxin Launches KX-7000 Desktop 8-Core x86 Processor to Power China's Ambitions

There's been a fire under it for decades man. It will be a decade yet before we really see the impact of sanctions I expect.


It would appear they have implemented the full x86-64 instruction set here. So either just not caring, or not limited. Either way they certainly have at least a license to basic x86 from cyrix->VIA lineage.

I thought Intel determined Cyrixs X86 licence was Not transferable?!.

Specific architectures and details are patented, there is hardly any patent on ISA as a whole. In addition, IBM has its own developments and contributions. They were respectively used in subsidiary company Sirix and, as a result of transactions, reached VIA and Zhaoxin. Could Intel be messing with IBM's way of doing business? I don't think Intel has a say in this case.

I actually owned a Cyrix 386, I'm surprised Intel didn't litigate clearly but fair enough.

Didn't Intel and AMD have to form a mutual agreement to avoid fighting over patents related to x86-64 between themselves? I don't remember VIA being included in that agreement tbh

Because they weren't. Cyrix had own cross-licensing agreement with Intel.

Either way they certainly have at least a license to basic x86 from cyrix->VIA lineage.

Cyrix "basic" implementation was completely home grown, so Intel lost all legal battles. They then signed cross-licensing agreement. And Zaoixin did not buy license itself, but a stake in a company owning the license and IP. As far as I remember it's over 50%.

Intel is only 50% of the equation. AMD is the other party, and I suspect they have no reason to agree on this.

It's more than 50%. It's also MMX, SSE, AVX, VT-x etc. VIA have been making x86-64 CPUs since 2011. So either some old agreement with AMD or cross-licensing conditions covers it as well. They could also implement it own way, like x86.
