Intel Xeon 28c/56th over here, without AVX512, anyway I never managed to max it out. Please note that it's a dual socket CPU and 28c/56th is the sum of those two. This is basically why I use to run multiple files at the same time. For instance, when we gotta encode MPEG-2 files for broadcast usage, I run up to 56 encodes at the same time, 'cause MPEG-2 encoders were meant to be used on monocore CPUs. Anyway, one of the reason why I never managed to max it out with x265 was that I'm using Avisynth on 4K 12bit contents which are brought up to 16bit for post-processing, but this kind of files are very poorly handled by Avisynth when it comes to speed and going through a pipe before reaching x265 doesn't help.
Anyway, if you want and if I'll have spare time I'll try to play with that a little bit more again with your settings.
