Dirty lie dude it is same chip. If you wanna efficient miner go for bitfury miner or under lock coincraft. If they do something at all it will be a trade of between power and hashing rate.
The math is very simple dude
1. Chip supplier gives you a figure of power at one volt or whatever chip power is
2. The above figure is taken from simulations not real chips and differs with let say 10 % from reality. When chip is Overclocked the difference is quite big
3. Add at least 10% for cd/cd 12v to 1 and on top 15at least psu loss
There is one slight chance for them to meet their figures if they putt wise as much chips as planned and under clock them. It is too late to do the math right know but they will roughly loose 60 chips costing 100 used each to make it happen and so on and on
Again it will be not their fault the chip needs power that is all
And they are aware of the fact they speak nonces unless instead of 220/120 v in your plugs you happen to have ONE VOLT dc
