Except they dont even have an accelerator design? RISC-V is just now mulling over matrix extensions, and I don't think special CPU extensions are ever going to surpass dedicated designs... and POWER is ahead of them at the moment. Also they have basically no presence in consumer PCs. Maybe they have potential in edge/embedded, but thats not really Nvidia's ballgame anyway.
