I have just noticed that two batches of the antminer s7 have been released at the same time with the sipping dates being the same.
I also noticed that the price of the s7 has decreased to 7.01 btc compared with the previous 9 btc. Is there a reason for this £300 decrease?
There's not a whole lot of speculation to do about something we already know. With people that already have a S7, we can tell that many units have issues running at 600hz. Some other do fine at 575hz and some other even have problem doing 550hz.
So yes we're looking at something similar. So they just split the batch into their performance, i'm guessing they're keeping the sub 575hz, which that would be speculation. In short, If you want to know, read the S7 thread.
