So who is buying the S7?
I think it has too little power. I thought it would have around 10 - 20 TH/s. But okay, it has the new chips.
When is 16nm coming? For me in Germany it is hard to mine with those prices for electricity... :/
And what kind of circuit are you going to run a 10-20THs miner? Remember, the S7 is aimed at the home miner.
I would rather call it a shed- or basement- or outside-of-home miner if it is really going to be 75dB or more as some are suggesting.
Unmodded S5 in batch1 and with initial software and only one fan was doing 72dB of "metallic"sound.
By saying "home miner", I mean that the S7 is designed to run on an average home's circuits rather than only in a datacenter. Where the person decides to place the miner in their home is irrelevant. But yes, a garage or basement is the best place to run most any miner.
