NVIDIA's RSX-40nm GPU uses the Curie architecture and is made using a 40 nm production process at Sony. With a die size of 114 mm² and a transistor count of 302 million it is a small chip. RSX-40nm does not support DirectX. Modern GPU compute technologies are not available. It features 24 pixel shaders and 8 vertex shaders, 24 texture mapping units and 8 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).
