I think this may be a bit too many instructions (I did not see hardware accelerated memcpy/memset though). I guess I would use only a small subset of them. Since RISC-V is a royalty free standard, writting directly assembly is worth it, until the abuse of a macro processor and code generation is avoided.
I want to share you optimism, but I advise you to keep your cool. There is a long road to reach the performance of x86/arm microarchitectures (it is harder for risc-v since the "market is over saturated"). And those performant implementations must get access to the best silicium node process... and that...
These are known "detonators" set up for next year. There's more we don't even know of. It is going to happen.
RISC-V is inevitable.
>As far as I know and specs wise
December 2021's batch of extensions done the magic. No hardware out there implements them.
Once it arrives (e.g. Veyron and Ascalon), the thorough disruption of the whole CPU landscape, from microcontrollers to supercomputers, starts.
The acceleration and massive momentum that we've seen to date is nothing compared to what's to come.
