What I'm trying to say is that maybe you have to extract a 20% or so from the peak numbers to obtain real throughoutput, BUT I HAVE NO IDEA OF SUPERCOMPUTING. It's just my estimation after looking at TOP500 supercomputers and Cell and Fermi whitepapers...
The thing about the ATi cards is that their SMID architechure seems less flexible than nVidia's MIMD route.
That is the reason I have doubts on its performance.
I am trying to understand this:
