Antminer S21 XP
The Antminer S21 XP is one of Bitmain's most advanced air-cooled Bitcoin miners, released in October 2024. It delivers 270 TH/s at just 3645 W, resulting in an excellent 13.5 J/TH efficiency — about 12% more efficient than the S21 Pro. Built on the latest-generation BM1370 chips with 91 chips per hashboard, it features a detachable OLED display for instant status readout. Aluminum-backed hashboards and advanced cooling ensure long-term, stable operation in both large-scale farms and hosting environments. Its high efficiency significantly lowers operating electricity costs while maximizing BTC output — an ideal choice for miners focused on improving ROI.
