Not great; VisionFive appears to be significantly less performant. https://browser.geekbench.com/v5/cpu/compare/17159543?baseline=15878552 https://browser.geek

  We're still in the early days of risc-v availability. Arm has been widely deployed and the compilers optimised by both individuals and companies. I expect this comparison to look better in a year (not better than rpi4, just a smaller gap)

  There are a few where it does win though -- I wonder what characteristics favor VisionFive in those?

  afaict rbpi cpu has vector instructions? if so, i wonder how much that contributes to the difference...?

    a lot.

      Fortunately, at least for video codecs, there's a hardware acceleration block, and it is significantly stronger than the one rpi4's SoC has. Unfortunately, there's no drivers in the current images, and it'll take time to have proper open drivers and integration with common APIs such as vdpau.

  U74-MC performance is not an unknown, and they can do much better than that. Of course, there's a lot of software factors holding it back, such as quality or lack of drivers. Benchmarks will be worth re-running in a few months, once some level of ecosystem is in place.
