My Bet is the S4. 2TH, 1400W.
Here is how I see it...
- Bitmain: S4 2TH, 1400W
- KnC: Pluto 8TH, 4500W
- Spondoolies: SP50 12TH, 6000W (4X PSUs)
I think we've pretty much found the ceiling with .5W/GH. Now we only have to know about the selling price for all of these. With Bitcoin price in big trouble, development is sure to slow. This should favor BitMain which develops on their own money rather than pre-order. Bitmain might be the big winner.
Will the S4 arrive before Christmas?
No Next year. Jan 7th will be the day it ships. 2100gh at 1150 watts. it will have an evga 1300 psu in it. A true beast.
