Mining Calculator Bitmain Antminer S21 Pro (234Th)

The heavyweight from Bitmain. The Antminer S21 Pro, boasting 234 TH/s, isn’t just another upgrade; it’s a display of power. Bitmain isn’t trying to catch up with competitors; it’s setting a new, almost unattainable standard for the entire industry. By releasing such a machine in the summer of 2024, immediately after the halving, the company clearly signals to the market: “We know the rules of the new game, and we hold all the trump cards.” This ASIC is a direct answer to the question of how to remain profitable with a halved block reward.

But the real magic of the S21 Pro isn’t in its astronomical terahashes; it’s in its diet. A consumption of 3531 W for such performance gives us a phenomenal energy efficiency rating of 15.1 J/Th. This isn’t just good; it’s a benchmark that competitors will have to strive for throughout the next year. In the world of industrial mining, where the battle is for hundredths of a cent per kilowatt-hour, such efficiency is a decisive factor. The S21 Pro generates maximum revenue while minimizing the primary expense.

From a constructive perspective, Bitmain adheres to its philosophy of a “reliable workhorse.” The elongated casing (400 mm) and the standard system of two powerful fans are time-tested solutions for efficient heat dissipation. The noise level of 75 dB is an expected trade-off for such performance, perfectly normal for industrial sites. No experiments with liquid cooling in the base model – only a classic, predictable, and easily maintainable air system. This is a pragmatic choice for those who value uninterrupted operation of hundreds and thousands of devices.

In summary, the Antminer S21 Pro (234Th) is the ultimate tool for mining in the post-halving era. It’s not built for experiments but for dominance. This is the choice for large, well-capitalized operators who think in terms of multi-year payback periods and for whom energy efficiency is the alpha and omega of their business. Currently, it is, without exaggeration, the king of the mountain in the world of SHA-256.
