ATI RS400

Default
RS400
ATI's RS400 GPU uses the R300 architecture and is made using a 130 nm production process. With a die size of 73 mm² it is a very small chip. RS400 supports DirectX 9.0 (Feature Level 9_0). For GPU compute applications, OpenCL version N/A can be used. It features 2 pixel shaders and 2 vertex shaders, 2 texture mapping units and 2 ROPs. Due to the lack of unified shaders you will not be able to run recent games at all (which require unified shader/DX10+ support).
