The GameCube GPU was a performance-segment gaming console graphics solution by ATI, launched on August 24th, 2000. Built on the 180 nm process, and based on the Flipper graphics processor, the device supports DirectX 6.0+. The Flipper graphics processor is an average sized chip with a die area of 120 mm² and 51 million transistors. It features 4 pixel shaders and 1 vertex shader 4 texture mapping units, and 4 ROPs. ATI includes 16 MB SDR memory, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 162 MHz, memory is running at 162 MHz.
Its power draw is rated at 45 W maximum. The console's dimensions are 150 mm x 161 mm x 110 mm, and it features a igp cooling solution. Its price at launch was 199 US Dollars.

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.
