With the S3 already outdated ( impossible to get ROI at current price and efficiency), the S4 being totally overpriced, I belive it is time that we should see an S5 in the next few months ?
my forecast specs are :
Power consumption : about 400w
GH/S: close to 1.000 GH/S
I'm going to assume you meant that it's going to be 1
TH/s and not the 1GH/s you wrote (maybe you meant 1000GH/s, and the "." was meant as the "," is used in the US). Unless Bitmain comes up with a new chip in the near future, you're not going to see too much efficiency difference than what is currently available. Their current-gen tech is about 0.7W/GH/s (the BM1382). They aren't going to get the kind of efficiency you're hoping for with that chip.
