    • MMX integer SIMD
    • 133 MHz 64-bit GTL+ front-side bus to GPU
    • 64KB L1 cache. 128 KB on-die L2 cache

Memory

  • Shared graphics memory sub-system
    • 64 MB DDR SDRAM at 200 MHz; in dual-channel 128-bit configuration giving 6400 MB/s
    • Supplied by Hynix or Samsung depending on manufacture date and location

Graphics processing unit

  • GPU and system chipset: 233 MHz “NV2A” ASIC. Co-developed by Microsoft and Nvidia.
    • Geometry engine: 115 million vertices/second, 125 million particles/second (peak)
    • 4 pixel pipelines with 2 texture units each
    • 932 megapixels/second (233 MHz × 4 pipelines), 1,864 megatexels/second (932 MP × 2 texture units) (peak)
      • Peak triangle performance (32pixel divided from fillrate): 29,125,000 32-pixel triangles/s raw or with 2 textures and lighting
        • 485,416 triangles per frame at 60 frame/s
        • 970,833 triangles per frame at 30 frame/s
    • 8 textures per pass, texture compression, full scene anti-aliasing (NV Quincunx, supersampling, multisampling)
    • Bilinear, trilinear, and anisotropic texture filtering
