Antminer S4

Bitmain Antminer S4 2,000 GHs
The enormously powerful and power efficient AntMiner S4 2THs is now available for sale globally.
The AntMiner S4 is the fourth generation mining rig by Bitmain. It uses the state of the art BM1382 chip powered by the 28nm tech process with ultra-low power consumption.
Power efficiency progress is reflected from the S1 to the S4 and is our focus to improve your investment and save on electricity bills.
The AntMiner S4 is built into 3U size box, although its hashrate is twice that of the S2. The S4’s design is hugely improved from S2’s experiences, using less hash blades and adjusting the space structure in each box to bring a light and portable model. It will be very convenient to deploy.
