Texture cache: 16 KB cache for even mipmap levels and surface textures, 8 KB cache for odd mipmap levels and lightmaps. Both caches two-way set associative.
Block coverage issue - 4-pixel horizontal blocks, expect 90% coverage with average-size triangles
Quake III arena - 200 FPS with all features on @ 800x600x32
- 400 MPIX/s
- 350.000 drawn triangles/s
- 3.5 MB of textures / frame, 670 MB/s of texture bandwidth
- Depth complexity of 4
