- snvzz 1y agoBest to wait for the RVA23 chips.
- brucehoult 1y agoOther than having RVV, that board is slower than a VisionFive 2, at least for what I primarily do (building software). Yes, even with 8 cores vs 4. Also the K1 chip offers support for 16 GB RAM, but the RV2 only offers 8 GB. I have 16 GB on the same chip on my LicheePi 3A.
- ekianjo 1y agoAre you sure about the "slower" part? Because I have both a VisionFive 2 and the OrangePi RV2, and the OrangePi RV2 is way faster in my different tests. Even in single core scenarios.
- brucehoult 1y agoYup. For example, Build Linux kernel commit 7503345ac5f5 with defconfig. VisionFive 2 ... with -j4, 3.37x faster than -j1 real 67m35.189s user 249m55.469s sys 13m35.877s ... with -j1 real 227m52.130s user 215m19.648s sys 12m7.831s LicheePi 3A ... with -j8 5x faster than -j1 real 70m57.001s user 514m33.367s sys 39m43.167s ... with -j4 3.28x faster than -j1 real 108m0.979s user 399m0.734s sys 30m47.136s ... with -j1 real 354m44.285s user 330m24.508s sys 24m12.196s When using all the cores the SpacemiT is not much slower, but single core it takes over 1.5x longer. On other tasks that don't stress the caches so much the SpacemiT can do well.
