How many 'CUDA cores' does each multiprocessor of a GPU have?

Question

I know that devices before the Fermi architecture had 8 SPs in a single multiprocessor. Is the count same in Fermi architecture?

Answer 1

The answer depends on the Compute Capability property of the CUDA device. The numbers are:

1. Compute Capability <= 1.3 --> 8 CUDA Cores / SM
2. CC == 2.0 --> 32 CUDA cores / SM
3. CC == 2.1 --> 48 CUDA cores / SM

See appendix G of the CUDA C Programming Guide.
