Finally, it should be noted that the reaction of professional miners to the T9 has not been especially positive. The general consensus appears to be that the T9 is a way for Bitmain to clear price of sub-standard chips, by running them at higher voltage to boost their reliability. The downside of this is degraded efficiency. Last updated on July 24th, at Pros More reliable than the S9 day warranty. Cons Lower hash rate than the S9 Relatively high power consumption.

It is heavy and delicate at the same time, but sounds like a jet.
This is for commercial-grade hashing. If you want to hash quietly in the home or have environmental factors, one may want to consider the R4.
Forum posts have referred to these as "wife-busters". This machine does belong within a server room type setting. One may want to consider learning on an older model because there is a little bit of technical knowledge needed.
It died after 3 months use, just beyond warranty expiration. Ran hot at recommended hash rate so down-clocked it to There is absolutely Zero support from both manufacturer and distributor.
Nothing grossly defective after examining boards someone suggested a loose transformer Left with a good expensive door-stop at best. Defective product, inadequate support Still running strong and hashing at three proper rate three months later Several of my friends are running Antminer S9 and convinced me it would be a price upgrade over my S7 rigs. It uses a mere 0. The S9 consumes about W more than the S7. Apart from the power supply, the S9 is a self-contained price. It requires no connection to another computer to interface with other Bitcoin nodes.
The S9 performs reliably in any well-ventilated space, whether a single or several unit s kept in a spare room or hundreds to thousands of units in a antminer mining center. On the other hand, the halving could bring about a higher Bitcoin price and reduced antminer, increasing profitability.
