Consumption is around 300 watts total and 78C die temp.
So... we are looking at ~600W total for around ~500GH? Obviously the 25% extra hashrate is nice, but I thought we were expecting the total power to be under 1J/GH.
I guess that isn't going to happen unless we underclock.
So essentially roughly the same power efficiency as KNC, shipped late and at higher cost.
So KNC wins, and will make much more money if there is ever a round #2 match...
Let's see if Cointerra gives HF an ass kicking at half the cost, they might even deliver by the end of the year
