Some of that could be related to the ISA but I'm hoping that it's just the fact that the current implementations aren't mature enough.
replyThe vast majority of the ecosystem seems to be focused on uCs until very recently. So it'll take time for the applications processors to be competitive.
Same experience here.
replyAt least for SBCs, I’ve bought a few orange pi rv2s and r2s to use as builder nodes, and in some cases they are slower than the same thing running in qemu w/buildx or just qemu
That has been the case so far but is changing this year.
replyThe SpacemiT K3 is faster than QEMU. Much faster chips are expected to release over the next few months.
I mean things like the Milk-V Pioneer were already faster but expensive.
One thing that has been frustrating about RISC-V is that many companies close to releasing decent chips have been bought and then those chips never appear (Ventana, Rivos, etc). That and US sanctions (eg. Sophgo SG2380).
Oftentimes slow is fine, when the work is parallel and the hardware is cheap
replywhich, sadly, isnt the case right now
replyIt is the case for embedded microcontrollers. An ESP32-C series is about as cheap as you can get a WiFi controller, and it includes one or more RISC-V cores that can run custom software. The Raspberry Pi Pico and Milk-V Duo are both a few dollars and include both ARM and RISC-V view. with all but the cheapest Duo able to run Linux.
