Question / Help CPU preset vs Bitrate

[Deleted member 121471]

Greetings.

Has anyone tested or can link me to any tests of CPU presets vs bitrate, specifically how much bitrate, in % or absolute values, is saved per CPU preset that is slower than "very fast", if I want equivalent image quality in the resulting file?

I could test it myself in a few weeks but I'd rather not duplicate efforts unnecessarily.

Found as 1st result from Google "x264 presets comparison" - the following search results are interesting as well.
