Is it really this much slower than a Raspberry Pi 5? https://browser.geekbench.com/v5/cpu/compare/23667112?baseli...

tldr; 236 vs 666 single core score

From your link it seems to be 3x slower. It's not clear to me why this comparison is relevant.

  • I was wondering about the value proposition. But I guess it's a more like a dev / tinkering board then.

    • Yep, the Pi 5 is an ARM though and you have to license the architecture to use it. RISC-V is open source, but currently sucks in pretty much all aspects compared to any other. This is still way in the early dev and build support phase.

  • For integer workloads it seems closer to 60% of RPi 5 performance. There are some benchmarks that depend on vector support or dedicated CPU instructions for good results, and they skew the results.

A TL;DR doesn't explain everything. The Milk-V Titan doesn't have Vector instructions or crypto, while the Pi 5 does. It's very clearly a broken benchmark.

This is why a bunch of RISC-V people won't buy boards without RV Vector instructions.
