SHA-256 comparison
Bitmain Antminer S21 XP Hyd vs Bitmain Antminer S21 Pro
The Bitmain Antminer S21 XP Hyd is 20% more efficient per TH, which is what decides the break-even electricity price below. Both machines are modelled with identical assumptions and your own rate.

Both machines assume a 1% pool fee at the current BTC price and network difficulty, running continuously. A highlighted figure is the better of the two on that measure — marked only where one genuinely is better, not on hashrate, power or revenue, which reflect the size of the machine rather than its quality. Highlighting is not a recommendation, and no manufacturer pays for placement here. Your rate is saved in this browser and applies across the site.
Our view
Bitmain Antminer S21 XP Hyd
473 TH/s · 5,676 W · 12.0 W/TH
The most efficient machine in this set at 12 W/TH, and the highest break-even electricity price as a result. Hydro cooling means it needs a water loop, so it is a hosted-site or purpose-built-facility machine rather than a garage one.
Bitmain Antminer S21 Pro
234 TH/s · 3,510 W · 15.0 W/TH
Air-cooled at 15 W/TH, which makes it far easier to deploy than the hydro models while staying competitive on efficiency. Still far too loud for a home without a dedicated, isolated space.
These are editorial judgements, not paid placements. Neither manufacturer has any influence over the ordering or the verdicts, and no purchase links on this page are affiliate links. Purchase price, warranty and availability are excluded because we do not yet publish a verified retailer feed — a comparison that invented them would be worse than one that omits them.
