3.2.2 PENTIUM III PROCESSOR

The Pentium III processor's architecture (Figure 3-3) includes the same core functionality as
described previously for the Celeron processor but includes a larger, 8-way set-associative L2
ECC cache, additional processing features, and higher processing speeds.

The Pentium III processor is software-compatible with Celeron, Pentium II, Pentium MMX,
Pentium, and x86 processors. The Pentium III processor features 70 FPU-based streaming SIMD
extensions (SSE) that, when implemented by appropriate software, can enhance 3D transforming
and speech processing operations. Operating system requirements for SSE support are as follows:
