Phoronix: StarFive VisionFive 2 Quad-Core RISC-V Performance Benchmarks

SiFive's HiFive Unmatched development board was interesting when it began shipping in 2021 with 16GB of RAM and four U74-MC RISC-V cores along with one S7 core. But pricing was rather steep at $665 USD. Fast forward two years, the StarFive VisionFive 2 has begun to enjoy wide availability and for $100+ this RISC-V development board features a quad-core RISC-V processor via the StarFive JH7110 SoC with integrated GPU, up to 8GB of RAM, HDMI 2.0 output, dual Gigabit Ethernet, dual USB 3.0 ports, and more for around $100 USD. Here are some benchmarks of this most interesting RISC-V single board computer in the ~$100 space to be released yet.

I'd like to see the output of

cryptsetup benchmark

on the 6.5-rc5 kernel.
Older kernels are slow;

That's pretty meaningless, the kernel used is very old and it should be compared to something similar like a pi 3b

Weirds me out a little that Michael apparently thinks any amount of nebulous software optimization will close the gap between a 2-wide in-order core and an aggressive 3-wide OoO uarch.

That's a bit disappointing. I expected it to be on par with the rpi 4. I doubt I'll get one for fun. But thanks for the benchmarks!

and no vector extension, ...

Wow. Pitiful performance. Hopefully they're better in 3-5 years.

That's their official downstream kernel at the moment... They are carrying the StarFive patches.

I never said I expect the VisionFive 2 to "close the gap"... Certainly there will be improvements and perhaps in some extreme cases may come close to closing the gap in some areas where comparing generic vs. very tuned AArch64 code paths right now, but no - I don't expect it to "close the gap" overall by any mans...

What about non cpu/gpu benchmarks?
For board like this people as well think about NAS or firewall usages, means (disk)I/O or Network could be interesting as well.
