Bitdeer unveiled the Sealminer A2 ASIC miner with 226 TH/s hash rate and 16.5 J/T efficiency, produced with TSMC and Desiweminer. The device aims to challenge Bitmain and other dominant players in Bitcoin mining hardware.

Bitdeer has introduced the Sealminer A2, a new bitcoin mining ASIC rated at 226 TH/s and 16.5 J/T. The company says mass production onboarding is underway as it pushes deeper into competition with major mining hardware manufacturers.

Bitdeer has introduced the Sealminer A2, a new ASIC miner rated at 226 TH/s and 16.5 J/T. The launch signals a deeper push into mining hardware as the company moves to compete with major manufacturers including Bitmain, Microbt, Canaan, and Auradine.

At an electricity cost of $0.04/kWh, all 14 leading Bitcoin ASIC miners tracked on April 23, 2026 remained profitable, with Bitmain’s Antminer S23 Hydro 3U topping the list at $31.62 per day.

Based on a hashprice of $36.46/PH/s on April 23, 2026, this guide reviews 14 leading ASIC miners at $0.04/kWh electricity. Bitmain's Antminer S23 Hydro 3U tops daily earnings at $31.62, with 13 rigs requiring liquid or immersion cooling.

On April 23, 2026, Bitcoin's hashprice stood at $36.46/PH/s, making all 14 monitored ASIC miners profitable at $0.04/kWh. Antminer S23 Hydro 3U leads with $31.62/day; only Proto Rig uses air cooling.

Bitcoin mining hardware in 2025 pushed past the 1 PH/s threshold, with hydro-cooled ASICs and tighter J/TH efficiency defining the industry’s newest competitive frontier.

Bitcoin mining hardware made a major leap in 2025, with top ASIC rigs reaching petahash-class performance and sharper energy efficiency. Hydro cooling, modular designs, and lower J/TH ratios are reshaping industrial mining competition heading into 2026.
