NVidia GPU programming tips are here. I just bought a GeForce GTX460 with 768 Mbytes GDDDR5to test drive CUDA and GPU programming.

How many cores in my GeForce graphics card?

When I looked at the GPU specification at NVidia for my GTX460, it says that the number of CUDA cores is 336.However, cudaGetDeviceProperties returned multiProcessorCount = 7. I was wondering why.It turned out that GTX460 consists of a GF104 GPU which has

   336 (CUDACores) = 7 (Streaming Multiprocessor Count) x 48 (Shader Processor = CUDA Core).

For More info on GeForce 400 series, see http://en.wikipedia.org/wiki/GeForce_400_Series. For comparison with other NVidia GPUs, seehttp://en.wikipedia.org/wiki/Comparison_of_Nvidia_graphics_processing_units.
