The product features of Bitmain Antminer T21 are as follows: High Hash Rate: It adopts advanced 5nm process chip technology, with a hash rate of up to 190TH/s. Through overclocking settings, it can be increased to 210TH/s at most, which has obvious advantages in mining cryptocurrencies such as BTC based on the SHA – 256 algorithm. Low Energy Consumption: The energy efficiency ratio is as low as 19J/T, and the rated power consumption is 3610W. This energy – efficiency ratio can effectively reduce the power cost and improve the profitability of mining. Excellent Cooling Performance: It is equipped with a customized heat – dissipation fin and a double – ball – bearing fan intelligent air – cooling system, which can run stably in an environment temperature of 25 – 45??. Convenient Remote Management: It supports Ethernet remote management. Users can monitor key parameters such as hash rate, temperature, and power consumption in real – time through a web – based interface or APP, and can also adjust the operation mode. Flexible Operation Mode: It supports self – adjustment from NEM to HEM mode, which can automatically adjust the operation mode according to the change of ambient temperature to maintain the best performance. Compact and Easy – to – install Design: The body size is 400??195??290mm, and the weight is 12.8kg. The compact size and relatively light weight make it have obvious advantages in space utilization and handling installation.
