ATI M68

ATI's M68 GPU uses the R500 architecture and is made using a 80 nm production process at TSMC. With a die size of 230 mm² and a transistor count of 384 million it is a medium-sized chip. M68 supports DirectX 9.0c (Feature Level 9_3). It features 36 pixel shaders and 8 vertex shaders, 12 texture mapping units and 12 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).
