Bitdeer SEALMINER A4 Series

What the generation covers

Bitdeer's shop lists all three models for SHA-256 mining (BTC/BCH/BSV). The air-cooled A4 Pro Air is rated at 336 TH/s on 3,662.4 W and the hydro-cooled A4 Pro Hydro at 680 TH/s on 7,412 W, both at 10.9 J/TH. The hydro-cooled A4 Ultra Hydro is rated at 886 TH/s on 8,372.7 W, or 9.45 J/TH, the lowest J/TH among the models listed. Across the generation that is 336 to 886 TH/s and 9.45 to 10.9 J/TH.

How the versions differ

The Pro Air and Pro Hydro share the same efficiency, and the Pro Hydro gives about twice the hashrate per unit. The Ultra Hydro gives about 30% more hashrate than the Pro Hydro (886 vs 680 TH/s) for about 13% more power (8,372.7 vs 7,412 W), so each terahash takes about 13% less energy. Against the A3 Pro Air's 12.5 J/TH, the A4 Pro Air uses about 13% less energy per terahash.

Announcement

Bitdeer launched the A4 series in April 2026, and its April 2026 update reported that mass production had begun.

Choosing within the SEALMINER A4 generation

Models in one generation share a chip platform but differ in cooling type, hashrate and efficiency. Start with the cooling type your site supports, then compare efficiency and power draw between the versions listed above. Use the compare checkboxes to put two to four models side by side.
