Nah, 'RISC-V is slow' is not exactly an uncommon sentiment: see, e.g., https://news.ycombinator.com/item?id=41920766

Not surprising, since the few physical RISC-V implementations that are available under-perform a decade-old Raspi by a significant margin, and that platform is not a rocket-ship to begin with.

Oops. Well, since recursive acronyms are widely-accepted in our industry as well, I'll just leave that one up.

You are out of date if you think there's no currently available commercial risc-v cores that can outperform the decade old raspberry pi 1 B+. Frankly, a 30 years old pentium 2 could outperform the first raspberry pi. It's a very low bar. And risc-v has crossed it many many years ago.
