Bitdeer achieves 9.7 J/TH efficiency with Sealminer A3 chip

Bitdeer Technologies Group has announced a breakthrough in energy efficiency for Bitcoin (CRYPTO:BTC) mining with its SEAL03 chip, achieving 9.7 joules per terahash (J/TH) during prototype testing.

The chip, designed for the upcoming Sealminer A3 mining rigs, was tested under low-voltage, ultra power-saving conditions.

Mass production of the Sealminer A3 is scheduled to begin in late 2025, as Bitdeer aims to compete in the high-efficiency mining hardware market.

The company is also advancing its Sealminer A4 development, targeting an unprecedented efficiency of 5 J/TH.

Initial tape-out for the A4 chip is expected by Q3 2025.

These advancements come as Bitdeer continues to expand its infrastructure globally to support next-generation mining technologies.

Bitdeer’s infrastructure projects include the phased energisation of a 100 MW hydro-cooling facility in Rockdale, Texas, which began operations in March 2025.

Over 500 Sealminer AI units are already operational at this site, with additional units expected to be delivered throughout the month.

In Norway, the company’s 40 MW Tydal Phase 1 project is nearing final regulatory approval, while construction of the 500 MW Jigmeling site in Bhutan remains on track for substation completion by the end of March.

Bitdeer management highlighted its focus on leveraging its global power portfolio of 2.6 GW to scale high-performance computing and artificial intelligence ventures.

Ongoing discussions with U.S.-based partners aim to establish large-scale projects that align with its chip roadmap and infrastructure plans.

The firm plans to present updates on these developments at several investor conferences through May 2025, including the ROTH Growth Conference and Bitcoin 2025.

“Efficient mining technology is key to sustaining profitability as margins tighten,” stated Bitdeer’s CEO Jihan Wu, emphasising the importance of these innovations in addressing industry challenges.
