RS740
ATI's RS740 GPU uses the R400 architecture and is made using a 55 nm production process. With a die size of 73 mm² and a transistor count of 120 million it is a very small chip. RS740 supports DirectX 9.0b (Feature Level 9_2). 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).
