Die Shot
ATI's M84 GPU uses the TeraScale architecture and is made using a 55 nm production process at TSMC. With a die size of 67 mm² and a transistor count of 181 million it is a very small chip. M84 supports DirectX 10.1 (Feature Level 10_1). Unknown texture mapping units and Unknown 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).
