The only two things that fermi really has are a very flexable design, programmers can make it flip waffles and the fermi has a very nice FP64 FMA execution system...
Ok thanks for pointing that out. It seems there are advantages and disadvantages to each implementation but ATI has no form of ECC/EDC on the cache. Also it will be irrelevant on the GeForce cards as ECC will be disabled.
