Bitmain's New S21 Bitcoin Mining Rigs Debut With up to 473 TH/s of Hashpower. Bitmain’s new Antminer S21 series mining rigs outperform market rivals in joules per terahash (J/T) efficiency. The first model, the S21 XP air-cooled unit, delivers 270 terahash per second (TH/s) with an efficiency rating of 13.5 J/T. As of now, with the hashprice at $0.0524 per TH/s per day, the S21 XP is projected to generate $10.84 in daily profits, assuming electricity costs $0.04 per kilowatt hour (kWh).Alongside the new air-cooled Antminer, Bitmain also unveiled the S21 XP Hydro ASIC mining rig. This hydro-cooled model offers a significantly higher hashrate and superior efficiency in joules per terahash. The Antminer S21 XP Hydro achieves an estimated 473 TH/s with an efficiency rating of 12.7 J/T. Given the current hashprice and $0.04 per kWh in operational costs, this machine is estimated to earn $21.48 per day.
