RISC-V by design and be ambition is for everything, serious compute and embedded. Its just that its far easier to release embedded chips and that standard for that was ready far earlier.
Serious compute simply takes far longer in terms of product cycle and the relevant standard came far later.
A lot of use for RISC-V is also not in places that is target at end consumer devices.
There is not much yet in terms of RISC-V PC? The HiFive Pro P550 should be coming out at some point. Or the Unmatched currently.

Companies working on high performance RISC-V are: Esperanto, SiFive, Ventana Micro Systems and Tenstorrent.
- httgp 3y agoNoob question - are they somehow better at AI/ML workloads than regular x86_64?
- panick21_ 3y agoWell, of course I don't have performance numbers or anything. In general, the RISC-V Vector Unit has very much been designed to make those workloads faster. Many new AI/ML companies are using RISC-V and Vectors but usually with some of their own non-standard stuff. Esperanto has Vectors with TPU. TensTorrent has done a lot of work on software to use their chip as a dataflow engine. And so on and so on. So essentially, Nvida is making a huge amount of money and all those companies will want a piece of it. I would say RISC-V Vector is a better design then x86 SIMD. RISC-V is also not done, there are efforts to standardize things like matrix and other things used for AI/ML workloads.
