SP's are different from CUDA cores. Typically higher clocked and more efficient. That's why a 480 CUDA core GTX480 outperforms a 1600 SP HD5870.
EDIT: I wonder if Nvidia will change architecture but still refer to them as CUDA cores?
Guess we won't know for sure until (hopefully) this week or next.
