I'd believe more in a heterogenous chip (e.g. MI300X, Apple M series, or even APUs) than in completely new chip tech.

- rbanffy 2y agoIt’s still two separate ISAs.
- winwang 2y agoI have a hard time believing that dealing with a singular ISA for two different compute cases would be an "obviously better" solution. I don't doubt that it's plausible/possible, especially if RISC-V + extensions are still simple, but then again, that's far outside my wheelhouse.
- rbanffy 2y agoEven with a GPU sharing memory with your CPU, calling GPU code is never as simple as doing a jump to that code. You need to set up the code the GPU will run and then let it loose on the data.
