Hello!
I'd like to know the difference between BMI2 and POPCNT. Which one is better (more stronger, faster, etc...)?

Check it yourselft trying these commands and compare:

For example:

> stockfish_popcnt.exe bench

Engine authors suggest BM12 if able to use it.

It depends on what kind of processor you have. If it's older than Sandy Bridge (the second generation of Core i), then x64, if it's newer, then POPCNT, if it's newer than Haswell (the fourth generation of Core i) is recommended BMI2.

The older machines won't run BM12 compiles anyway.
