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:
Operating System
Level of SSE Support
Windows 95 No SSE support
Windows 98, OSR0 SSE support though ISV and OpenGL 6.1 applications only
Windows 98, OSR1 SSE support though ISV, OpenGL, and DirectX applications
Windows 2000 SSE support with ISV, OpenGL, and DirectX applications
Windows NT 4.0 SSE support requires driver and Service Pack 4 (SP5 recommended)
