Which binary of Stockfish 7 should I use? Stockfish 7 for Windows comes with 3 64-bit binaries:


stockfish 7 x64 bmi2.exe
stockfish 7 x64 popcnt.exe
stockfish 7 x64.exe


All 3 of them work on my system. Which one gives the best performance?
Open a terminal/console. Run the stockfish program, if the engine crashes move to the next one.

Type bench for the working binaries, and pick the one with best nodes/second.
