Bitdeer Unveils 9.45 J/TH Miner as Bitcoin Hashprice Remain Under Pressure
Bitdeer (NASDAQ: BTDR) has launched a new generation of bitcoin mining hardware, touting improved energy efficiency to 9.45 J/TH as miners grapple with the weakest profitability environments ever.
The company said on Tuesday that its SEALMINER A4 series, powered by its proprietary SEAL04 chips, can achieve an efficiency of 9.45 J/TH, marking a step forward in reducing power costs — the largest expense for mining operators.
The new lineup includes three models designed for different deployment setups: the hydro-cooled A4 Ultra Hydro and A4 Pro Hydro, as well as the air-cooled A4 Pro Air.
The A4 Ultra Hydro is rated at 886 TH/s and has a power consumption of about 8,372 watts. The A4 Pro Hydro delivers 680 TH/s at 10.9 J/TH, while the A4 Pro Air is rated at 336 TH/s at the same efficiency level.
The launch comes as Bitcoin miners face sustained margin pressure, with hashprice — a key measure of mining revenue — hovering in the low-$30 per PH/s per day range. At those levels, profitability has tightened across the industry, particularly for operators running older, less efficient machines.
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.
Many operators have pulled back on large-scale fleet expansion, instead prioritizing balance sheet preservation, selective upgrades, or even selling portions of their bitcoin holdings to fund revenue diversification into HPC colocation. Orders for new machines have become more price-sensitive, and delivery timelines across the sector have shortened compared with the tight supply conditions seen during previous bull cycles.
