Xenos (graphics Chip)

The Xenos is a custom graphics processing unit (GPU) designed by AMD (former ATI), used in the Xbox 360 video game console. Developed under the codename "C1," it is in many ways related to the R520 architecture and therefore very similar to an ATI Radeon X1800 series of PC graphics cards as far as features and performance are concerned. However, the Xenos introduced new design ideas that were later adopted in the R600 series, such as the unified shader architecture. The package contains two separate silicon dies, the GPU and an eDRAM, featuring a total of 337 million transistors.
