Die Shot

NVIDIA's G71 GPU uses the Curie architecture and is made using a 90 nm production process at TSMC. With a die size of 196 mm² and a transistor count of 278 million it is a small chip. G71 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).
