The Bitmain Antminer S23 Immersion (442Th/s) is a next-generation, oil-cooled Bitcoin ASIC miner built for industrial-scale mining operations seeking ultra-high performance with superior thermal efficiency. Designed for the SHA-256 algorithm, this model is optimized exclusively for Bitcoin (BTC) mining.

Delivering up to 442 TH/s at 5304W, the S23 Immersion achieves an impressive 12 J/TH efficiency, making it one of the most efficient immersion-cooled Bitcoin miners in its generation. In addition, the miner supports a secondary low-power operating mode (368 TH/s at 11 J/TH), allowing operators to fine-tune performance based on electricity pricing and infrastructure constraints.

Scheduled for release in January 2026, the S23 Immersion features a factory-optimized oil immersion design, drastically reducing noise, heat stress, and component degradation compared to air-cooled systems. This enables higher sustained hashrates, longer hardware lifespan, and denser rack deployments.

Backed by Bitmain’s Antminer engineering, the S23 Immersion is ideal for immersion-hosting facilities, institutional miners, and enterprise BTC farms operating at scale.
