What's the difference between CUDA and stream processors?

[Rigged089]

I'm in a massive dilemma about buying either a 660ti or a 7950.

But the specifications for the Nvidia cards have CUDA cores and AMD have stream processors. What's the difference? (if any)

To be honest without going into the inner workings of the the individual GPU's there is not an awful lot of difference, just like Intel have "Turbo Boost 2.0 and AMD have "Turbo Core" they both clock the CPU higher when fewer cores are in use but call them different things. The Cuda cores or Stream processors are the names that Nvidia and AMD have given to their programmable shader units, they are different in each architecture and that is why they have different amounts but they essentially do the same thing.

As for a 660Ti or a 7950, the AMD7950 is the more powerful especially once overclocked and it would be my suggested choice out of the two.

The difference is the architectural design, it used to be quite different but they are becoming more and more similar as AMD starts to focus more on compute.
