G73 BGA

NVIDIA's G73B GPU uses the Curie architecture and is made using a 80 nm production process at TSMC. With a die size of 100 mm² and a transistor count of 177 million it is a small chip. G73B supports DirectX 9.0c (Feature Level 9_3). For GPU compute applications, OpenCL version N/A can be used. It features 12 pixel shaders and 5 vertex shaders, 12 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).
