ATI's R520 GPU uses the R500 architecture and is made using a 90 nm production process at TSMC. With a die size of 288 mm² and a transistor count of 321 million it is a medium-sized chip. R520 supports DirectX 9.0c (Feature Level 9_3). It features 16 pixel shaders and 8 vertex shaders, 16 texture mapping units and 16 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).
