In which case I can only assume you have not done much significant work in both?
Cuda is a MUCH more developed system making development for programmers much easier and more flexible. It also performs better (usually..) on similar code where there is a close mapping, and has a close mapping to codes more often (in our experience).

There will of course be exceptions.

And thats ignoring the fact the the industry is 'heavily invested in Cuda', but thats really a side issue.

Great, a whole single case - it couldnt perhaps be that this particular case maps o to the amd hardware better than the nvidia? (there are most certainyl a bunch of outlying cases for each architecture, where something maps directly to hardware on them, but software fallback on the other..).
