Before Fermi release, NV defined SPs as SM(MCU) * 8.
When sm_20 Fermi GPUs were released(GTX 465,470,480), it was changed to SM * 32 .
But some guy in NV is a smartass, so it was again changed to SM * 48 for sm_21 GPUs(GTX 460 and other).
SM(MCU) - Shader Multiprocessor.
sm_xx - compute capability of GPU.
Since there is no GetSP() function, the application computes SPs by getting SM count and multiplying it by 8.
Ignore it, and use GPU-Z to get correct values.
