At 9.45 J/TH, the A4 series would imply a fleet power hashcost of roughly $13.6 per PH/s per day, assuming an electricity rate of $0.06 per kilowatt-hour. That leaves a relatively wider margin cushion compared with legacy rigs, many of which operate closer to or above the current hashprice threshold when factoring in total costs.

The new machines build on Bitdeer’s prior SEALMINER A3 generation, which was rated at around 12.5 J/TH, as competition among hardware makers intensifies, even though the weak mining economics have also cooled demand for new mining hardware.
