Bitmain Antminer S21 XP Hyd 473Th/s Bitcoin ASIC Miner, SHA-256 ASIC

The Bitmain Antminer S21 XP Hyd 473Th/s Bitcoin ASIC Miner is a hydro-cooled Bitcoin (BTC) ASIC built for hyperscale operations. Running the SHA-256 algorithm, it's engineered for the kind of facility where uptime is measured in months and efficiency is the metric that decides whether the operation is profitable.

Here's what you actually get. The Bitcoin ASIC delivers 473 TH/s of hashrate at 12 J/TH efficiency, and efficiency is the number that decides whether your operation is profitable at any given power cost. Anywhere above $0.06/kWh, the efficiency gap between this unit and older hardware compounds into real revenue over a year of uptime.

What hydro-cooling actually means for you in practice: continuous peak operation without thermal throttling, dramatically extended hardware lifespan, and the option to recapture waste heat for facility heating or industrial applications. Hydro units typically run quieter than air-cooled equivalents too, which gives you more flexibility on where the facility lives. If your power budget is fixed and you want maximum BTC produced inside that envelope, hydro is the answer.
