The Antminer S21 Pro is the Pro version of the Antminer S21, an innovative bitcoin mining device developed by Bitmain. The Antminer S21 Pro has a hashrate of up to 234TH/s and consumes just 3531 watt of power.

Bitmain launched the S21 series with advanced 5nm chips, which can increase the efficiency up to 40% compared to the previous S19 model, and for the S21 Pro, it reaches 15.0 J/T.

There is no doubt that the Antminer S21 Pro will start a new round of the bitcoin mining arms race.
