arm has toxic IP locks.
Everybody sane will want to move away from them, there is nothing chinese specific.
The most performant RISC-V implementations are from the US if I am not too mistaken.
Wonder if that hardware can handle an AMD 9070 XT (resizable bar). If so, we need the steam client to be recompiled for RISC-V and some games... if this RISC-V implementation is performant enough (I wish we would have trashed ELF before...)
Is there an actual U.S. RISC-V CPU that achieves competitive performance? I think the performance leaders are currently based in China.
There's a difference between announcement, offering IP for licensing (so you still have to make your own CPUs), shipping CPUs, and having those CPUs in systems that can actually boot something.
For instance, SiFive in the US, but last time I did check them, their RVA23 CPUs on their workstation boards did not have cache-line size vector instructions (only 128bits aka sse grade I think), RVA23 mandates the same "sweet spot" for a cache line size than on x86_64: 64bytes/512bits.
Box64 already runs Steam (and a good number of games) on RISC-V.
Box64 also runs on LoongArch
Yep... but RISC-V large and performant implementations won't access the latest silicon process for a good while... better to push for native support to help.
