At the World Digital Mining Summit in Las Vegas, Bitmain, a leading manufacturer of application-specific integrated circuit (ASIC) bitcoin mining rigs, introduced two new mining machines. Both models—one air-cooled and one hydro-cooled—boast an efficiency rating of under 14 joules per terahash.
Bitmain Introduces S21 XP and S21 XP Hydro
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).
