HardOCP ha realizzato un dettagliato report sulla GPU ATi, nome in codice Xenos, presente in Xbox 360.
| Xbox 360 Video System Performance & Specifications
| |
| Custom ATI Graphics Processor | *500 MHz
*10 MB embedded DRAM *90nm process *48-way parallel floating-point dynamically-scheduled shader pipelines- Unified shader architecture |
| Polygon Performance | *500 million triangles per second |
| Pixel Fill Rate | *16 gigasamples per second fillrate using 4X MSAA |
| Shader Performance | *48 billion shader operations per second |
| Memory |
*512 MB GDDR3 RAM *700 MHz DDR *Unified memory architecture |
| Memory Bandwidth | *22.4 GB/s memory interface bus bandwidth *256 GB/s memory bandwidth to EDRAM *21.6 GB/s front-side bus |
| HD Game Support | *All games supported at 16:9, 720p and 1080i, anti-aliasing *Standard definition and high definition video output supported |
Unità pixel e vertex shader unificate (in futuro con le schede WGF 2.0 ci saranno anche su PC) e 10MByte di ram embedded per prestazioni al top anche con antialiasing massiccio. Al momento nel mondo computer desktop non troviamo nulla di simile.
