Which binary should I choose ?

The latest release should always be the best. The different architecture builds are:

🖳  64: generic 64-bit build. Should work on all 64-bit processors of your operating system.

🖳  - x86_64: x86_64 build. Same as previous one, but enables use of the prefetch` instruction, which places RAM addresses in cache for faster access. Should work on almost all 64-bit processors.

🖳 - x86_64-modern: same as previous one, but also enables use of the popcnt` (Population Count) instruction. Should work on all > 2006 64-bit processors.

🖳  - x86_64-bmi2: same as previous one, but also enables use of the `pext` (Parallel Bit Extract) instruction. Should work on all AMD processors with Excavator arch or newer, and all Intel processors with Haswell arch or newer.
