"So there may be a x32 (32 bit) version a x64 (64 bit) version. Also you may see bmi2 and popcnt versions. These additional versions are compiled to take advantage of special features built into specific microprocessors. The speed gained by running these versions are small but feel free to try them. If they don’t run just switch back to the plain version."

"I think in general, the 'best' is x64_bmi2, then x64_popcnt, then x64 and x32 is 'worst'. That said, if your processor doesn't support bmi2 it won't run, etc. So pick the best one that doesn't crash.
To confirm this I ran the benchmarks given above.
On my PC (nodes/sec): stockfish_32: 1380872 stockfish_64: 1764951 stockfish_64_popcnt: 1813557 stockfish_64_bmi2: 1886284"
