What makes the S9 the antminer electrically-efficient mining bitminer to date is the cutting-edge manufacturing process. It uses a mere 0. The S9 consumes about W more than the S7. Starting from the 12th of June, the earliest batch of S9s will be available for order directly from Bitmain. However, if you have low electricity costs, your odds are better than the miner paying for itself within a reasonable time frame. Ultimately though, a lot of which depends on the Difficulty and Bitcoin price. Judging value in this space is a complicated exercise, although it would appear that in the near future nothing vastly technologically-superior to the S9 is likely to be released.
The release cycle of a new generation of mining hardware every few months is likely to decrease from this point on, as manufacturers have transitioned to cutting-edge 16 antminer 14nm designs. The S9 is a bitminer unit, excluding the power supply. No connection is needed to another computer to interface with other Bitcoin nodes. See questions and answers.

The price of the Antmier s9 varies a lot. This is the bitminer expensive miner on the market today because its superior mining abilities. If you own a PSU of an old Bitcoin miner you might be able to use that as well. Seeing as most people will probably rush to buy the new Antminer s9 you may want to consider getting the older model Antminer s7 at a discounted price antminer to lower demand.
My overall rating is a 3. These are great miners that can replace about 3 s7s. However, the miner gets way too hot over the s7s.
