Flipper GPU Notes

Floating Point Operations:
8 GFLOPS

TEV "Texture EnVironment" engine
(similar to Nvidia's GeForce-class "register combiners")

Fixed-function hardware transform and lighting (T&L),
20+ million polygons in-game

648 megapixels/second
(162 MHz × 4 pipelines)

648 megatexels/second
(648 MP × 1 texture unit) (peak)

Peak triangle performance:
20,250,000 32-pixel triangles/s raw and with 1 texture and lighting or 337,500 triangles a frame at 60 fps

8 texture layers per pass, texture compression, full scene anti-aliasing

8 simultaneous hardware light sources
up to 32 software light sources

Bilinear, trilinear, and anisotropic texture filtering
Multi-texturing, bump mapping, reflection mapping, 24-bit z-buffer

24-bit RGB/32-bit RGBA color depth Hardware limitations sometimes require a 6r+6g+6b+6a mode (18-bit color), resulting in color banding.
