Hello, not new to the bitcoin business aspect, expanding my horizons.  i deal in all kind of mining tools for Bitcoin but the S-series antminers very are efficient for any Bitcoin Miner.

S7
The S7 is powered by a 28nm BM1385 ASIC chip. Kept cool by dual fans (or a single fan in the case of a particular batch), 135 of these chips are spread across 3 boards. The strong metal casing features a tongue and groove system which allows for the neat arrangement of multiple miners.
PROS

    High 4.73 TH/s hashrate, and efficient at 0.25 Joule per GH/s

    Priced reasonably

    Prominent miner with ample guides and parts available

CONS

    Eclipsed by 16nm miners (AntMiner S9) and forthcoming 14nm miners

    Demands high-end PSU due to high power consumption of ~1350 Watts

    Little noisy at 62dB
STATISTICS
4.73 Th/s
0.25 W/Gh
8.8 pounds



 S9
A vital enhancement upon the 28 nm design usual to other modern mining devices is the 16 nm fabrication process used in the manufacture of the S9, existing power supplies, at least those of sufficient wattage, are fully compatible with the S9.
As per the inputs discussed above, the S9 will yield 0.285 BTC / $159 per month and 3.36 BTC / $1939 in a year.
What makes the S9 the most electrically-efficient mining device to date is the cutting-edge manufacturing process.
PROS

    At ~14 TH/s, it has the highest available hashrate

    At ~0.1 Joule per GH/s, it is very efficient

CONS

    it is considered expensive but the best and worth the buy.

    Sold separately, you need more for Power Supply
STATISTICS
13.5 Th/s
0.098 W/Gh
8.1 pounds
