They're quite different and there isn't really a specific number because they're good at different things and some things work on one but not the other. (cuda obviously)

The best way to tell how two cards will perform relative to each other is to look up some benchmarks of both cards in similar PCs.

Well nvidia just calls their Stream Processor count Cuda Cores. I think the number was estimated somewhere from 3 - 5 AMD Stream Processors = 1 nVidia Stream Processor.

eg. the GTX580 has 512 Stream Processors (Cuda Cores) and the HD7970 has some 2000 Stream Processors and is around some 30% faster.
