The AntMiner S4 is the fourth generation Bitcoin mining rig by Bitmain. It uses the BM1382 chip powered by the 28nm tech process with ultra-low power consumption.
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.
