Mining Calculator Bitmain Antminer S21 Hyd (335Th)

With the S21 Hydro, Bitmain isn’t just raising the bar; it’s launching it into the stratosphere. The figure of 335 TH/s on the SHA-256 algorithm is not just a flagship metric; it’s a declaration of total dominance in the high-performance segment. This hash rate takes industrial mining to an entirely new level of power density. This titan is not built for experiments but for large-scale farms where every square meter and every kilowatt must operate with maximum efficiency.

The key to such power and stability is hydro-cooling. It allows Bitmain to extract the maximum from the chips without fear of overheating, achieving phenomenal energy efficiency of 16 J/Th (5360 W / 335 Th). This is a metric that determines profitability for years to come. A secondary benefit is the noise level of 50 dB. Forget the roaring turbines characteristic of air-cooled models. The S21 Hydro operates no louder than office equipment, fundamentally changing the requirements for room sound insulation and allowing for much denser equipment placement.

Of course, such performance comes at a price, and the bill is in kilowatts. A consumption of 5.36 kW requires a very serious approach to power infrastructure and, more importantly, the presence of an external cooling loop. This is not a device that can be “just plugged into a socket.” It requires integration with a dry cooler or another liquid heat dissipation system. The elongated and narrow body (410 x 170 x 209 mm) directly indicates its purpose – dense installation in specialized racks for hydrominers.

In summary, the Antminer S21 Hydro is an ultimatum to the market and a new gold standard for industrial Bitcoin mining. It offers an unprecedented combination of hash rate and energy efficiency but requires a corresponding professional approach and capital investment in infrastructure. For operators ready for such investments, the S21 Hydro becomes the most efficient cryptocurrency mining tool available today, pushing air-cooled competitors to the background.
