The Bitmain Antminer S21 XP Hyd (473Th/s) is an ultra-high-performance hydro-cooled Bitcoin ASIC miner, designed for industrial-scale mining operations demanding maximum hashrate, superior energy efficiency, and long-term operational stability. Built for the SHA-256 algorithm, this miner is optimized exclusively for Bitcoin (BTC) mining.

With an extraordinary 473 TH/s hashrate and a power draw of 5676W, the S21 XP Hyd achieves an industry-leading efficiency of just 12 J/TH, making it one of the most efficient Bitcoin miners ever released. Its hydro-cooling system allows sustained peak performance, reduced thermal stress, and extended hardware lifespan — ideal for data centers, containerized deployments, and professional hosting facilities.

Released in October 2024, the Antminer S21 XP Hyd represents Bitmain’s most advanced mining architecture to date. Hydro-cooling dramatically lowers operational noise to just 50 dB, enabling high-density deployments without the drawbacks of traditional air-cooled systems.

Featuring reliable Ethernet connectivity and engineered for continuous 24/7 operation, the S21 XP Hyd is the definitive solution for miners seeking maximum output per unit, exceptional efficiency, and enterprise-grade performance.
