If 48 threads gives 21x speed than this is very good, but I can't see this on these graphs.

This information is enough. Sometimes adding hyperthreading to such a test can be bit missleading. In this case we gain close to 20% from 'fake' threads, which is very good result.
I should look closer at PC descriptions

Grapghs should always have units

I think z will be great addition to existing libraries, specially in ffmpeg.

I would like to see noise generator and maybe Sierra algorithm, which seams to be as good as Floyd, but can be way faster.
Floyd+tiny amount of noise gives amazing results for high quality video masters.
