Bitmain, a leading Bitcoin mining rig producer, revealed its latest product on Wednesday: the air-cooled T21 Antminer. The device is designed to achieve a hash rate of 190 terahash per second (TH/s) and exhibits an efficiency of around 19 joules per terahash (J/T).
Coming on the heels of the recent product release from its rival, Microbt, Bitmain’s new T21 Antminer enhances the company’s broad lineup of mining equipment. Launched on October 25, the T21 can reach a peak performance of 190 TH/s, while maintaining a 19 J/T efficiency.
In a move to cushion customers against volatile Bitcoin prices, Bitmain also rolled out an optional price protection plan. This scheme guarantees customers compensation if Bitcoin’s market price dips beneath a predefined level during a specific protection timeframe. The company offers varied compensation tiers based on the duration of this protective period and promises prompt payment following any qualifying price drop.
Bitmain’s T21 Antminer follows the recent introduction of two devices from their S21 series. The S21 Hyd boasts up to 335 TH/s at 16 J/T efficiency, while the S21 air-cooled model offers around 200 TH/s with a 17.5 J/T efficiency. Although the S21 air-cooled variant displays marginally better performance metrics than the T21, the new T21 outperforms the older S19 models in efficiency. The T21’s specifications include a power usage of 3,610 watts, and the product is set for delivery in early 2024.
In terms of physical dimensions, the T21 closely mirrors the S21 air-cooled model. 2023 has been a busy year for the three dominant Bitcoin mining equipment manufacturers: Bitmain has released three new models, Canaan two and Microbt three.
