I don't think so, I run a CI on a VisionFive2 and it is terribly slow, takes ~8x compared to my Ryzen 3600 CPU. It's not helped by also having fairly limited IO speed on the NVMe side (board issue? unclear)

A 6 core OoO CPU with 6-wide µop issue running at 4.2 GHz is 8x faster than a 4 core in-order 2-wide CPU running at 1.5 GHz?

(6/4) * (6/2) * (4.2/1.5) = 12.6

Who would ever have guessed it might be 8x faster, without running the test?
