What if they are not the same?
I'm not sure what happens if they're not the same. I think one of the guys in the Hardware section actually did test it. Perhaps it was Bill. But I don't remember the results. I just remember that multiple identical GPUs were tested and Pr/AME scaled accordingly.
All of us with new Mac Pros are also taking advantage of dual GPUs (with OpenCL) as we have no choice in the matter.
