ATI's Mach64 LT GPU uses the Mach architecture and is made using a 500 nm production process at TSMC. With a die size of 90 mm² and a transistor count of 1 million it is a very small chip. Mach64 LT supports DirectX 5.0. It features 1 pixel shaders and 0 vertex shaders, 1 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).
