My gear is an old:

I7-4790 16GB RAM

How many tokens by second?

Even at 160kbps, maybe 1/1.000.000 people can recognice a FLAC vs MP3 trying 10 times (continuous) using expensive headphones and players, 320kbps is overkill, I prefer a FLAC and just encode to Opus.

Right now Opus is better and can be played in web browsers, smartphones, YouTube and Netflix are using that for awhile.
