On Wednesday, bitcoin mining rig manufacturer Bitmain announced the launch of a new air-cooled BTC miner, the T21 Antminer. The new device has a production capacity of up to 190 terahash per second (TH/s) and maintains an efficiency rate of approximately 19 joules per terahash (J/T).
Bitmain presents Antminer T21
Following the recent reveal of Microbt’s latest mining rig, competitor Bitmain has added the T21 Antminer to its wide range of hashing devices. On October 25, Bitmain introduced the T21, capable of delivering 190 TH/s with an efficiency rate of 19 J/T.
Additionally, the company has introduced an optional bitcoin price fluctuation plan, which ensures that customers receive compensation if BTC prices fall below the strike price on a reference day within a protected period.
Bitcoin’s float protection plan offers various tiers depending on the length of the protected period, with Bitmain stating that “compensation will be paid immediately following the triggering event.”
The T21 Antminer is the latest in a series of releases from Bitmain, following two new S21 series devices revealed last month. The S21 Hyd achieves up to 335 TH/s with an efficiency rate of 16 J/T, while the air-cooled S21 miner delivers up to 200 TH/s with an efficiency rate of approximately 17.5 J/T.
Although the S21 air-cooled machine offers slightly higher ratings compared to the T21, the latter surpasses the Antminers S19 in efficiency ratings. The T21’s specifications detail a power consumption of 3,610 watts and launch is expected in the first quarter of 2024.
The T21 is also comparable to the air-cooled Antminer S21 in terms of size and weight. Several new devices were launched this year by the three major bitcoin mining machine manufacturers: Bitmain with three, Canaan with two, and Microbt with three.
