Graphics processing unit

File:Ic-photo-nVIDIA--XGPU--(X-BOX-GPU).png

GPU and system chipset: 233 MHz "NV2A" ASIC. Co-developed by Microsoft and Nvidia and essentially a variant of Geforce 3 chips.
Geometry engine: 115 million vertices per second, 125 million particles per second (peak)
4 pixel pipelines with 2 texture units each
Peak fillrate:
Rendering fillrate: 932 megapixels per second (233 MHz × 4 pipelines)
Texture fillrate: 1,864 megatexels per second (932 MP × 2 texture units)
Realistic fillrate:
Rendering fillrate: 250–700 megapixels per second, with Z-buffering, fogging, alpha blending and texture mapping[https://web.archive.org/web/20010331050522/http://cube.ign.com/news/32458.html Graphics Processor Specifications], IGN, 2001
Texture fillrate: 500–1400 megatexels per second (250-700 MP × 2 texture units)
Peak triangle performance: 29,125,000 32-pixel triangles per second, raw or with 2 textures and lighting (32-pixel divided from peak fillrate)
485,416 triangles per frame at 60 frames per second
970,833 triangles per frame at 30 frames per second
Realistic triangle performance: 7,812,500–21,875,000 32-pixel triangles per second, with 2 textures, lighting, Z-buffering, fogging and alpha blending (32-pixel divided from realistic fillrate)
130,208–364,583 triangles per frame at 60 frames per second
260,416–729,166 triangles per frame at 30 frames per second
4 textures per pass, texture compression, full scene anti-aliasing (NV Quincunx, supersampling, multisampling)
Bilinear, trilinear, and anisotropic texture filtering
Performance lies between a Geforce 3 Series GPU and a Geforce 4 Series GPU. This is due to the added vertex shader present on the ASIC, thus doubling the vertex output compared to Geforce 3 ASICs. Clock speed is the same as the original Geforce 3 series GPU (233MHz) thus slower than Geforce 4 series starting at 250MHz.{{cite web|url=http://www.anandtech.com/show/853/3 |title= Hardware Behind the Consoles - Part I: Microsoft's Xbox - The X-IGP |publisher=Anandtech.com |date=2001-11-21 |access-date=2010-11-11}}
