General

Generally speaking, the Geode GX supports the i686 (Pentium Pro) instruction set. MMX and 3DNow! Enhanced instructions are also supported, (and indicated by the correct CPUID bits), so applications which check those bits should use MMX as usual. Additionally, there are some special AMD Geode instructions, but they are not used by the GNU compiler.

Specific Instruction Sets

  • i586 (Pentium)
  • MMX & MMX extensions
  • AMD 3DNow!
