BITMAIN ANTMINER S7: with BM1385 chip

Bitmain is pleased to introduce our latest machine, the Antminer S7. This powerful machine features a small form factor, like our previous Antminer S5, while utilizing the denser hash board arrangement of the more recent S5+. This is the first Bitmain product to use our recently announced BM1385 chip, which is not only more than twice as power efficient as the BM1384 chip before it, but is also the most power efficient chip available to consumers today.  The Antminer S7 has a more dense configuration than previous Antminer machines, using 145 chips in the same space that the S5 used only 60 in. The S7 uses just 1042 watts of electricity to deliver a whopping 4.05 terahashes per second of pure mining power. S7 Specifications: 1. Hash Rate: 4.73 TH/s ±5% 2. Power Consumption: 1250 W (at the wall, with AC/DC 93% efficiency, 25C ambient temp) 3. Power Efficiency: 0.25 J/GH (at the wall, with AC/DC 93% efficiency, 25°C ambient temp) 4.  Rated Voltage: 11.60 ~ 13.00V 5. Chip quantity per unit: 145x BM1385 6.
