Mersenne Forum or

SSE41, AVX2, AVX512, and AVX512-IFMA refer to instruction set extensions that the versions respectively support.
SIQS, ECM, and YAFU's prime sieve all get progressively faster with more modern extensions.

Pick the best one that your CPU supports.
Roughly speaking:
- If you have an Ice Lake, Tiger Lake, Rocket Lake, or Sapphire Rapids CPU, use AVX512-IFMA.
- If you have an Intel SkylakeX or certain Cannon Lake or Cascade Lake CPUs, use AVX512.
- If you have an Intel Haswell CPU or newer (newer than 2013), use AVX2.
- If you have an AMD Zen4 or Zen5 CPU, use AVX512-IFMA.
- If you have another AMD CPU newer than 2015, use AVX2.
- Otherwise use SSE41.
