The product features of Bitmain Antminer S21 are as follows: High Hashrate: The Antminer S21 has a hashrate of up to 200TH/s, which means it can perform a large number of calculations per unit of time, increasing the probability of obtaining cryptocurrency mining rewards. Low Energy Consumption: Its energy efficiency ratio is 17.5J/T, which is quite excellent in terms of energy consumption, helping to reduce the power cost of mining. Advanced Chip Technology: It adopts advanced 5nm chip technology, which improves the hashing speed and productivity while reducing power consumption. Good Environmental Adaptability: The Antminer S21 can operate stably for a long time in a relatively high – temperature environment, and the maximum adaptable ambient temperature is 45 degrees Celsius. Efficient Cooling System: The air – cooled version is equipped with two high – performance fans, which can effectively reduce the working temperature and noise of the equipment, ensuring the efficient and stable operation of mining. Intelligent Management: It supports remote management and monitoring. Users can view the device status and adjust mining parameters at any time through dedicated management software, which improves the convenience of operation. Modular Design: It adopts a modular design, which is convenient for replacing faulty components, reducing maintenance time and cost. Simple Interface: It has a simple and easy – to – understand interface, which can intuitively display the mining status and performance indicators, facilitating users to monitor and adjust. Support for Multiple Algorithms: It supports the sha256d algorithm and can mine a variety of digital currencies based on this algorithm, such as BCH, BTC, and DGB – SHA256D, having good flexibility. Compact Design: Compared with previous models, Antminer S21 is smaller and lighter, which is more suitable for the deployment of multiple miners in a limited space.
