Sealminer A4 Series Debuts as Bitdeer Hits New Bitcoin Mining Efficiency Record

Key Takeaways:

• Bitdeer launched the Sealminer A4 Ultra Hydro connected April 7, 2026, hitting 9.45 J/TH efficiency, among the champion figures successful the industry.
• The A4 series, powered by Bitdeer’s SEAL04 chips, improves connected the A3 series’ 12.5 J/TH, cutting powerfulness costs for miners facing choky post-halving margins.
• BTDR shares gained astir 2.8% connected motorboat day, with nary shipment dates oregon pricing disclosed yet.

Sealminer A4 Ultra Hydro Delivers 886 TH/s astatine 9.45 J/TH for Bitcoin Miners

The Singapore-based institution released the A4 lineup done its Sealminer brand, the in-house ASIC part that Bitdeer uses to make and nutrient its ain mining hardware. The bid runs connected Bitdeer’s latest SEAL04 chips, built connected precocious process nodes, and represents the company’s clearest measurement yet toward competing straight with established hardware makers similar Bitmain and MicroBT.

Three models marque up the A4 series, each targeting antithetic deployment conditions. The A4 Ultra Hydro, the flagship hydro-cooled unit, delivers 886 terahash per 2nd (TH/s) astatine 8,372.7 watts with a rated ratio of 9.45 J/TH. The A4 Pro Hydro reaches 680 TH/s astatine 7,412 watts astatine 10.9 J/TH. The A4 Pro Air, the air-cooled option, produces 336 TH/s astatine 3,662.4 watts, besides rated astatine 10.9 J/TH.

Bitdeer notes that powerfulness ratio carries a tolerance of positive oregon minus 5%, and hashrate and powerfulness depletion transportation a tolerance of positive oregon minus 10%. The A4 Ultra Hydro’s 9.45 J/TH standing marks a notable betterment implicit Bitdeer’s erstwhile generation. The Sealminer A3 series, launched successful September 2025, achieved betwixt 12.5 and 14 J/TH.

Earlier A2 Pro units ran astatine 14.9 J/TH. Each procreation has moved person to the sub-10 J/TH threshold that Bitdeer had been targeting astatine the instrumentality level. Lower ratio figures straight trim energy costs per bitcoin mined. That matters to operators close now. Bitcoin hashprice has remained nether unit since the April 2024 halving chopped artifact rewards from 6.25 BTC to 3.125 BTC, compressing margins for miners moving older, little businesslike hardware.

The hydro-cooled models are designed for high-density information halfway deployments wherever vigor absorption is simply a constraint. Both hydro units connection a low-noise illustration alongside optimized thermal performance, which Bitdeer says supports instrumentality stableness and uptime astatine scale. The A4 Pro Air provides flexibility for sites that cannot enactment liquid cooling infrastructure.

Bitdeer operates arsenic a vertically integrated provider, managing spot design, instrumentality production, and information halfway operations crossed the United States, Norway, Bhutan, and Ethiopia. The A4 rigs are expected to enactment some outer hardware income and Bitdeer’s interior self-mining fleet, which the institution has been expanding done successive Sealminer deployments.

BTDR shares dipped astir 1% connected the announcement day, not excessively accordant with however the banal has responded to anterior hardware motorboat events. Bitdeer did not disclose pricing, pre-order details, oregon shipment timelines successful the announcement. Bitdeer’s announcement leafage had not yet been updated with A4 details astatine the clip of reporting.

The A4 motorboat extends a spot improvement roadmap that Bitdeer has described arsenic targeting astir 5 J/TH astatine the spot level successful aboriginal generations. The institution has antecedently shown sub-10 J/TH results successful chip-level benchmarks nether optimized conditions, with the A4 bringing that show into commercially delivered hardware.

Bitdeer’s vertical integration strategy means it controls costs and specifications crossed the afloat supply chain alternatively than sourcing chips from third-party foundries oregon purchasing machines from competitors. That exemplary gives the institution much power implicit hardware output and timing, though it besides concentrates R&D hazard internally.

No accumulation volume targets oregon transportation schedules were provided alongside the announcement.
