    maximizing performance

    Hi

    I have a GTX570M (notebook).

    By profiling, i seem to find the following specs:
    336 cuda cores
    7 SM Streaming Multiprocessor

    As each SM has an x amount of cuda cores I calculated the number of cuda cores per SM to be 336/7=48.

    However, documentation out there seems to suggest that the fermi architecure has 32 cuda cores per SM. So am I calculating incorrectly? Why do I get 48 instead of the expected 32?

    thanks

    Your calculation is correct: the GTX570M uses the GF114 architecture, which has 48 cores per SM, while the GF110 (the original Fermi architecture) has only 32 cores per SM.
