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.

The introduction of Bitmain’s S21 series highlights the relentless pace of innovation in bitcoin mining technology. As the industry advances, these highly efficient machines set new standards, potentially driving competitors to enhance their offerings. Bitmain’s emphasis on reducing energy consumption while increasing profitability underscores a crucial trend in the sector, balancing operational expenses with economic incentives.
