The Geode's instruction set is a mix of several instruction sets. As per data book (2.1 - CPU Core, pg.15):
General
Generally speaking, the Geode GX is a combination the following instruction sets:
- Intel's Pentium(r)
- AMD-K6(r)
- Athlon(tm) FPU
- AMD Geode Castle
Specific Instruction Sets
In particular (and from AMD's documentation) it supports the following instruction sets:
- Pentium
- Pentium Pro
- 3DNow! (AMD-K6 and Athlon processors)
- MMX (Athlon processors)
- subset of Geode Castle (including special SMM instructions)
- does not support SSE, except for the subset supported in Athlon's 3DNow! Enhanced.
- does support MMX for Athlon (itself a subset of Pentium 3 KNI)
