The Antminer S21 is hailed by the industry as the most powerful ASIC mining machine in history. Since its official launch in September 2023, it has been extensively purchased by various international mining companies. Today, let’s take a comprehensive look at the technical specifications, profitability, and impact of this mining machine on the miner community.
Ⅰ. Technical Specifications of the S21
The S21 miner comes in two versions: the S21 air-cooled and the S21 Hyd water-cooled. The air-cooled model is suitable for a variety of mining environments, with a computing power of 200TH/s and an efficiency of 17.5J/TH. Compared to the air-cooled model, the water-cooled model is suitable for higher performance mining environments. Its superior cooling capacity also means higher operational capability and longevity. The water-cooled model’s computing power reaches a staggering 335TH/s, with an astonishing efficiency of 16 J/TH, making it the most efficient mining machine in history.

Ⅱ. Profitability of the S21
Taking the S21 200T air-cooled model as an example, its daily Bitcoin production is about 0.0005695 BTC (data as of March 7, 2024). Meanwhile, one of the hottest mining machines in February 2024, the S19k Pro 120T, produces about 0.000204 BTC per day. Even after the Bitcoin halving in 2024, when the S21’s output drops to about 0.0002845 BTC, its profitability remains strong enough to support miners through the next four-year cycle.
Ⅲ. Impact on Miners
After the Bitcoin halving, the S21, with its robust profitability, is likely to gradually become mainstream globally. Its powerful computing power may increase the total global computing power, consequently, the actual amount of Bitcoin that older machines with lower computing power can mine each day will be less than half of what they could mine before the halving. Thus, after its launch, the S21 quickly became a hotly sought-after product by global mining giants, such as CleanSpark and Iris Energy, who order thousands of units to gain a competitive edge in mining capacity.
However, for small-scale miners, the high hardware cost of the S21 requires them to consider their purchasing power and Bitcoin price fluctuations to determine the most economical time to invest. After the Bitcoin halving, only machines with an efficiency below 20J/TH will shine, and the S21 will undoubtedly become a must-have model for almost all Bitcoin miners.
