Die Shot

NVIDIA's NV25 GPU uses the Kelvin architecture and is made using a 150 nm production process at TSMC. With a die size of 142 mm² and a transistor count of 63 million it is a small chip. NV25 supports DirectX 8.1. For GPU compute applications, OpenCL version N/A can be used. It features 4 pixel shaders and 2 vertex shaders, 8 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).
