ATI M64

M64-M

M64-S

M64-CSP128

ATI's M64 GPU uses the Ultra-Threaded SE architecture and is made using a 90 nm production process at UMC. With a die size of 100 mm² and a transistor count of 105 million it is a small chip. M64 supports DirectX 9.0c (Feature Level 9_3). Modern GPU compute technologies are not available. It features 4 pixel shaders and 2 vertex shaders, 4 texture mapping units and 4 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).
