The Antminer S21 is a high-performance ASIC miner designed for profitable Bitcoin mining using the SHA-256 algorithm. It delivers a powerful hashrate of 151 TH/s while consuming 3317 W, achieving an efficiency of 22.0 J/TH. This makes it a strong choice for miners focused on efficiency and long-term performance.
The Bitmain Antminer S21 is the air-cooled entry into the S21 family: 151 TH/s on SHA-256 from 3,317 W at 22 J/TH. Because it uses standard air cooling it drops straight into any conventional mining rack or hosting facility with no water loop and no special infrastructure, which makes it by far the easiest S21 to deploy and the usual starting point for a first serious Bitcoin machine.
