I wonder how much of the performance will improve when compilers get better at RISC-V. It's been a long time since I could beat the compiler at optimizing assembly on x86, yet in the end merely unrolling a loop and keeping an eye on write-read stalls I managed to get a simple "multiply array by const" about 56% less time (more than twice as fast): https://github.com/gnuradio/volk/pull/619 https://github.com/gnuradio/volk/pull/619 And that's with hardware that doesn't even have vector instructions! I'd understand GCC not supporting that yet. Some other quickstart docs and hot takes from me on this hardware: https://blog.habets.se/2023/01/VisionFive-2-quickstart.html https://blog.habets.se/2023/01/VisionFive-2-quickstart.html Edit: Oh yeah, if you can decipher my tables then you can compare some performance ray tracing with pov-ray here: https://qpov.retrofitta.se/stats https://qpov.retrofitta.se/stats
