Antminer T21 is the latest Bitcoin miner from Bitmain, launched in February 2024. With an ultimate hash rate of 190Th/s and power consumption of 3610W, it gives an excellent energy efficiency of 0.019j/Gh. Advanced air cooling system promotes instant heat dissipation and aids longevity.

What is the difference between the Bitmain Antminer T21 190TH and the S21 200TH Bitcoin Asic Miner?:
The Antminer S21 and the Antminer T21 are Bitmain's latest mining devices, manufactured for Bitcoin mining based on the SHA-256 algorithm, but they differ in some features.
The Antminer S21 stands out for its high performance, offering a hash rate of up to 200 TH/s with an efficiency rate of about 17.5 J/TH for the air-cooled version.
This model is focused on a balanced combination of performance and energy efficiency , Conversely, the Antminer T21 offers a hash rate of 190 TH/s at an efficiency of 19 J/TH.
The chips have been specially designed for operation at high ambient temperatures up to 45°C, with an emphasis on energy efficiency.
Both models reflect Bitmain's pursuit of innovation and the provision of powerful, efficient mining solutions for the cryptocurrency market.
The decision between the S21 and the T21 depends on the specific needs and preferences of the user, including factors such as performance, efficiency, and operating conditions.

Key Features:

Hash Rate: The Antminer T21 190T boasts a formidable hash rate of 190 terahashes per second (TH/s), making it a powerful contender in the mining market. This high hash rate enables miners to efficiently process a large number of cryptographic calculations, increasing the chances of successfully mining Bitcoin blocks.
Energy Efficiency: Despite its high hash rate, the Antminer T21 190T maintains excellent energy efficiency. It utilizes advanced ASIC chip technology and optimized power management systems to achieve a low power consumption rate per terahash, ultimately reducing energy costs for miners.
Reliability: Bitmain is known for its commitment to quality and reliability in its mining hardware. The Antminer T21 190T undergoes rigorous testing and quality control processes to ensure stable and reliable performance, even under demanding mining conditions.
