Microsoft's Xbox 360 video game console contains a custom graphics chip produced by ATI, known as "R500", "C1", or more often as Xenos. Some of these features include the embedded DRAM (eDRAM). The Xenos also features the “True Unified Shader Architecture” which dynamically loads and balances pixel and vertex processing amongst a bank of identically capable processing units. This differs greatly from past-generations PC graphics chips that have separate banks of processors designed for their individual task (vertex/fragment). Another feature presented in Xenos is the hardwaresurface tessellation to divide a surface into smaller triangles, similar to TruForm in terms of functionality, which is an advanced feature as it is not presented even in the DirectX 10 specification. The recent generation Radeon R600 GPU core inherited most of the features presented in Xenos, except eDRAM.
