Only AVX512 with Intel MKL and it's rather factor of 2 or slightly more compared to AVX2 capable CPU running OpenBlas. However, there are so few AVX512 capable CPUs so that point is kind of moot.Jhoravi wrote:I heard that SSE/AVX extensions for matrix multiply improves speed by a factor of 4. Can the CPU version be speedup this much?

Thanks. Does that mean the current Leela already supports AVX2? Or maybe speed increase not significant?Milos wrote: Only AVX512 with Intel MKL and it's rather factor of 2 or slightly more compared to AVX2 capable CPU running OpenBlas.
