Auradine AT2880 Bitcoin Miner Hits 17 J/TH Efficiency in Test

Mining service provider BitsBeTrippin’ has reviewed the performance of Auradine’s AT2880 hardware, a U.S.-designed Bitcoin ASIC chip and miner system poised to compete with Chinese incumbents.

BitsBeTrippin’ founder Michael Carter shared a review video on Monday featuring two Auradine AT2880 miners, demonstrating an efficiency of approximately 17 J/TH after two days of testing and operation.

In the test, one unit was set to a power target of 3,850 watts, producing 222 TH/s with a real-time power draw of 3,900 watts—resulting in an efficiency of 17.5 J/TH. This performance is comparable to Bitmain’s Antminer S21 model.

The second unit was configured to operate at 150 TH/s in a lower power mode, consuming 2,500 watts and achieving an efficiency of 16.8 J/TH. Lower power modes reduce a miner’s hashrate output but improve efficiency, making them favorable during periods of low Bitcoin hashprice.

Auradine initially announced the launch of its Teraflux AT2880 Bitcoin miner in November 2023, highlighting a hashrate range of 0–260 TH/s with optimal efficiency of 16 J/TH. Shipments began in July 2024, with production volumes said to be ramping up in Q3 2024.

Previously, BitsBeTrippin’ reviewed Auradine’s earlier generation Teraflux miner, the air-cooled AT1500. That model delivered a hashrate of 180 TH/s with an efficiency of 25.34 J/TH in high-power mode. In low-power mode, the AT1500 achieved 112 TH/s at 23.1 J/TH.

At Bitcoin’s current hashprice environment—less than $55/PH/s following the latest difficulty adjustment on Monday—Auradine’s AT2880 yields mining revenue of approximately $0.13 per kilowatt-hour.
