Bitdeer launches SEALMINER A4 sequence mining rigs that includes 9.45 J/TH effectivity and as much as 886 TH/s hashrate, fulfilling its chip improvement roadmap.
Bitdeer Applied sciences Group (NASDAQ: BTDR) has launched its SEALMINER A4 sequence mining rigs, hitting an influence effectivity benchmark of 9.45 joules per terahash that positions the Singapore-based firm among the many most effective ASIC producers within the trade. The announcement marks the completion of Bitdeer’s beforehand outlined chip improvement roadmap.
The brand new lineup runs on Bitdeer’s proprietary SEAL04 chips and is available in three configurations focusing on totally different deployment eventualities. The flagship A4 Extremely Hydro delivers 886 TH/s at 9.45 J/TH whereas consuming 8,372.7 watts. For operations preferring hydro-cooling at a cheaper price level, the A4 Professional Hydro affords 680 TH/s at 10.9 J/TH effectivity.
Mining operations with out liquid cooling infrastructure can go for the A4 Professional Air, which produces 336 TH/s on the identical 10.9 J/TH effectivity whereas drawing 3,662.4 watts. Bitdeer notes all specs carry a ±5% variance on effectivity and ±10% on hashrate and energy consumption.
Why Effectivity Issues Proper Now
With Bitcoin buying and selling round $69,163 as of April 7, miners are working in a post-halving setting the place each joule counts. The 2024 halving reduce block rewards to three.125 BTC, making operational effectivity the distinction between profitability and working at a loss for a lot of operations.
The 9.45 J/TH determine on the A4 Extremely Hydro represents a significant enchancment over previous-generation machines. For context, older S19-era machines usually function above 30 J/TH—that means the A4 sequence may theoretically produce the identical hashrate at roughly one-third the electrical energy price.
Bitdeer’s Vertical Integration Play
In contrast to pure-play miners who purchase gear from third events, Bitdeer has been constructing out its personal chip design and manufacturing capabilities. The corporate, which spun off from Bitmain in 2021 and went public by way of SPAC in April 2023, operates knowledge facilities throughout the USA, Norway, Bhutan, and Ethiopia.
This vertical integration technique carries greater R&D prices however affords higher margins if the {hardware} performs as marketed. Bitdeer reported vital Bitcoin manufacturing progress in January 2026 and accomplished a registered direct providing of 5.5 million shares in February, suggesting the corporate is well-capitalized to scale manufacturing.
The hydro-cooling fashions goal large-scale operations the place warmth density turns into a limiting issue. Bitdeer claims the superior cooling system maintains efficiency in high-density environments whereas preserving noise ranges low—a consideration for amenities close to populated areas.
Pricing and transport timelines weren’t disclosed within the announcement. Miners evaluating the A4 sequence will need to consider complete price of possession, together with any infrastructure upgrades wanted for hydro-cooling deployments, towards present and projected community problem.
