M22 X300

ATI's M22 GPU uses the R300 architecture and is made using a 110 nm production process at TSMC. With a die size of 74 mm² and a transistor count of 107 million it is a very small chip. M22 supports DirectX 9.0b. 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).
