Maybe it's just me, but when you tell me Bitfury has a 2800 score and KNC a score of 90, that really seems odd. Especially considering KNC's gigahash/watt is better than Bitfury's or BFL's. It really makes me question the relevance of this metric to me. Are you saying KNC, or someone, if they had access to KNC's design could replace it with a design that's 30 times more efficient? Are we saying KNC's design is basically one giant fuckup? Doesn't seem to make sense or accord with known facts.

I'm gonna assume that we simply just don't have enough technical details to make a determination and that's why KNC still hasn't been added to the OP list.
