For KNC to compete with Bitfury they should have delivered weeks ago, now it's simply too late. KNC first said they would deliver this Summer, then it became September and now it's (hopefully) before the end of September. I know it's a tight schedule, but Bitfury has shown they can deliver when they say they can deliver, KNC so far has not. Hashrate would need to be over 600Gh/s and power consumption under 600W to compete with Bitfury, I don't see that happening.
