Block Diagram
NVIDIA's G70 GPU uses the Curie architecture and is made using a 110 nm production process at TSMC. With a die size of 333 mm² and a transistor count of 302 million it is a large chip. G70 supports DirectX 9.0c (Feature Level 9_3). For GPU compute applications, OpenCL version N/A can be used. It features 24 pixel shaders and 8 vertex shaders, 24 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).
