Bitmain Antminer T21 190TH/s – SHA-256 Bitcoin ASIC Miner 3610W

The Bitmain Antminer T21 delivers a hashrate of 190 TH/s on the SHA-256 algorithm with a power consumption of approximately 3610W in Normal Energy Mode. This results in an outstanding energy efficiency of 19 J/TH, making the Antminer T21 one of the most power-efficient Bitcoin miners in its class. The T21 190TH uses Bitmain's advanced chip technology to balance high hashrate performance with manageable power draw. For miners focused on maximizing profitability per watt, the Antminer T21 190th offers an excellent entry point into efficient Bitcoin mining without the premium pricing of top-tier S-series models.

It achieves about 19.0 J/TH in typical conditions (25–30 °C) in the Normal The Antminer T21 specs include 190 TH/s hashrate on SHA-256, 3610W power consumption, and 19 J/TH energy efficiency. The unit requires a 380-415V AC three-phase power supply and operates within 0-45 degrees Celsius ambient temperature with 10-90% non-condensing humidity. The T21 features advanced air-cooled heat dissipation with integrated fans and connects to mining pools via an RJ45 Ethernet interface. The Antminer T21 power supply requirements and PDU compatibility should be verified before installation. Its compact form factor fits standard mining rack configurations, making the Bitmain Antminer T21 straightforward to deploy in professional mining facilities.

The Antminer T21 190th profitability depends on Bitcoin price, network difficulty, and electricity costs at your location. With 190 TH/s of SHA-256 hashrate and only 3610W power consumption, the T21 achieves a competitive 19 J/TH efficiency that keeps operating costs low. This makes the Antminer T21 profitability attractive compared to older-generation miners with higher power draw per terahash. The T21 mines Bitcoin and Bitcoin Cash on the SHA-256 algorithm. For an accurate daily and monthly profit estimate, use an online mining calculator with your local electricity rate and current Bitcoin difficulty to assess Antminer T21 190TH earnings potential.

The T21 was released around February 2024, and although it shares many The Antminer S21 vs T21 comparison shows key differences in both performance and price. The Antminer T21 delivers 190 TH/s at 19 J/TH, while the S21 offers higher hashrates starting at 200 TH/s with better efficiency around 17.5 J/TH. The T21 was released in early 2024 and shares much of the S21's hardware architecture but is positioned as a more affordable entry point. For miners comparing Antminer T21 vs S21, the T21 provides excellent value per terahash with slightly lower efficiency, making it ideal for operations where upfront cost matters more than absolute efficiency. Both models mine SHA-256 coins including Bitcoin and Bitcoin Cash.
