US-Designed Bitcoin Miner Delivers Promising Results

Auradine’s latest bitcoin miner, a U.S.-designed ASIC chip, is making waves in the mining hardware market after tests demonstrate an efficiency comparable to Bitmain’s leading miner.

Auradine’s AT2880 Challenges Chinese ASICs

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.
