Hi all, and happy editing Not VERY useful for CinelerraGG yet, still I found whole topic attractive enough :} http://www.bealto.com/gpu-benchmarks_mem.html I compiled benchmarks for my machine, with two simple fixes, and uploaded result to github: https://github.com/Randrianasulu/MPBenchmarks IMO my current devices quite fast: ===== Host to device copy 223 424 771 1182 1770 2147 2403 2378 2506 2501 1490 1828 756 743 777 771 776 708 683 0 Device to host copy 325 613 1155 1971 3320 4811 6282 7188 8039 8316 7039 5471 2817 2695 3107 3256 3221 2634 2716 0 copyN 327 651 1272 2189 3300 4486 5419 5932 6193 6266 6299 6320 6330 6345 6348 6349 6346 6335 0 0 For fastest NVA3 gpu (reclocked manually) GPU<->GPU copy still slow ..... https://gitlab.freedesktop.org/mesa/mesa/-/issues/3479 This is with very hacked mix of two experimental mesa branches ... Master (mesa3d) doesn't support compute on nv50-era cards. This bench requires images(2D) support, and works with OpenCL 1.1 driver
