M66-P
ATI's M66 GPU uses the Ultra-Threaded SE architecture and is made using a 90 nm production process at TSMC. With a die size of 150 mm² and a transistor count of 157 million it is a small chip. M66 supports DirectX 9.0c (Feature Level 9_3). Modern GPU compute technologies are not available. It features 12 pixel shaders and 5 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).
