ATI's Mach64 GPU uses the Mach architecture and is made using a 600 nm production process. With a die size of 90 mm² and a transistor count of 1 million it is a very small chip. Mach64 does not support DirectX. Modern GPU compute technologies are not available. It features 1 pixel shaders and 0 vertex shaders, 0 texture mapping units and 1 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).
