Which precompiled version should I use?
As of version 2.12, the following precompiled versions are available:
yafu-x64-sse41.exe
yafu-x64-avx2.exe
yafu-x64-avx512.exe
yafu-x64-avx512-ifma.exe
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.
See here for more information:

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 a Zen4 or Zen5 AMD CPU, use AVX512-IFMA.
- If you have another AMD CPU newer than 2015, use AVX2.
- Otherwise use SSE41.
