Bitmain Antminer S23: Hidden Features Your Bitcoin Mining Setup Needs

The delivers 69% more hashrate and operates at 41% higher power efficiency than the Antminer S21. This Bitcoin mining hardware offers three distinct cooling configurations: air-cooled, water-cooled, and immersion-cooled models Bitmain Antminer S23

The efficiency specifications set this ASIC miner apart from previous generations. The S23 Hydro operates at 9.5 watts-per-terahash, becoming the first Bitcoin miner to achieve efficiency below 10 W/TH. Performance numbers demonstrate clear capabilities—the air-cooled S23 produces 318 TH/s, while the water-cooled S23 Hydro reaches 580 TH/s.

Current profit calculations show potential returns of $13.95 per day or approximately $5,093.50 per year. The S23 series includes specific features that directly impact mining operation efficiency and profitability. This analysis covers the key features that make the Bitmain Antminer S23 a practical upgrade for Bitcoin mining operations.

Antminer S23 Models and Their Core Specs

The Bitmain Antminer S23 lineup includes four distinct models, each engineered for specific mining environments and performance requirements. All models utilize advanced SHA-256 ASIC technology that supports mining Bitcoin, Bitcoin Cash, and other compatible cryptocurrencies.

S23 (Air) — Entry-Level Performance

The S23 (Air) delivers 318 TH/s while consuming 3,498 watts, achieving an efficiency rating of 11 J/TH. This air-cooled version features four high-performance fans, operates at approximately 75dB noise level, and requires standard 380-415V power input. Miners seeking straightforward deployment without specialized infrastructure will find this model accessible yet powerful.

S23 IMM (Immersion) — Advanced Cooling

The S23 IMM (Immersion) generates between 368-442 TH/s at 11-12 J/TH efficiency, drawing 4,400-5,304 watts. Designed specifically for immersion cooling systems using dielectric oil, this model eliminates fan noise, extends hardware lifespan, and performs well in extreme environments.

S23 Hydro — Flagship Performance

The flagship S23 Hydro produces 580 TH/s hashrate and industry-leading 9.5 J/TH efficiency rating while consuming 5,510 watts[92]. This water-cooled unit operates at less than 65dB noise level and features a closed water circuit for enhanced thermal management.

S23 Hydro 3U — Enterprise Solution

The enterprise-focused S23 Hydro 3U delivers 1.16 PH/s (1,160 TH/s) while maintaining the same 9.5 J/TH efficiency, though power consumption increases to approximately 11,020 watts[92].

Power and Cooling Requirements

All S23 models require three-phase industrial power (380-415V), with the water-cooled variants operating at inlet coolant temperatures between 20-50°C. The hydro-cooling system reduces noise by 80% compared to air-cooled predecessors and minimizes overheating, extending hardware lifespan.

These specifications represent substantial improvements over previous generations, with the S23 producing 69% more hashrate and operating 41% more efficiently than the Antminer S21.

How does the S23 compare to other ASIC miners?

The S23 achieves a 245% performance increase over the previous S21 generation while reducing power consumption per terahash by over 40%. This positions the S23 Hydro as the market leader with its 9.5 J/TH rating.

Comparing the S23 with the MicroBT WhatsMiner M63S shows significant differences. The M63S delivers 411 TH/s but operates at approximately 18.44 J/TH—nearly double the energy consumption of the S23 Hydro’s 9.5 J/TH. The air-cooled S23 model operates at 11 J/TH efficiency, outperforming many competitors in energy economy.

Daily operational costs reveal practical differences. The S23 (Air) requires approximately €5.04 daily at €0.06/kWh, while the S23 Hydro 3U consumes €15.89. However, the S23 Hydro 3U generates revenue of €71.23 per day before electricity costs, providing superior return on investment.

The S23 series offers practical advantages beyond raw performance. The hydro-cooling system operates at under 65dB, substantially quieter than standard miners producing over 80dB. Space efficiency provides additional value—one hydro miner replaces three air-cooled units, reducing infrastructure requirements.

Current market alternatives include the Antminer S21 XP+ Hydro (500 TH/s) and the Bitdeer SealMiner A2 Pro Air. These units offer substantial hashrates but cannot match the S23’s efficiency threshold.

For miners focused on long-term sustainability, particularly after Bitcoin halving events, the S23’s efficiency advantage directly supports maintained profitability as mining difficulty increases and rewards decrease.

What Makes the S23 a Smart Investment

Bitmain Antminer S23 delivers strong financial performance in the post-halving environment. Bitcoin rewards dropped from 6.25 to 3.125 BTC per block in April 2024, requiring miners to prioritize equipment that maintains profitability with reduced margins.

The financial numbers are clear. At EUR 0.04 per kWh electricity costs, the standard S23 generates EUR 15.99 daily (0.0002 BTC) while consuming EUR 3.61 in power, creating a 22.5% profit margin. This balance between hashrate output and operational costs helps miners adapt to lower block rewards without sacrificing returns.

The S23’s power efficiency (11 J/TH for air-cooled, 9.5 J/TH for hydro models) positions it for long-term competitiveness beyond 2025. As electricity costs increase and regulatory pressures mount, this low power consumption translates to reduced total ownership costs and operational flexibility.

Bitmain offers flexible payment options, including BTC pledging and installment plans. These financing alternatives help miners manage cash flow during the current market transition period.

The S23 addresses global mining challenges effectively. Bitmain established its in December 2024 and continues expanding American manufacturing capabilities to reduce tariff impacts. This manufacturing shift helps US-based miners avoid the 25% tariffs on Chinese imports first US-based production line

The S23’s cooling options accommodate different operational requirements without performance compromise. The air-cooled variant requires no specialized infrastructure yet delivers solid returns, while hydro and immersion models provide advanced efficiency for sophisticated operations, optimizing facility utilization with double the hashrate per rack space.

The S23 represents both a technological advancement and a strategic economic asset for current mining conditions.

Conclusion

The Bitmain Antminer S23 provides clear performance advantages for Bitcoin mining operations. The device delivers 69% more hashrate while consuming less power than previous generations. The three cooling options—air, water, and immersion—allow miners to choose configurations that match their operational requirements.

The S23 Hydro’s 9.5 J/TH rating sets a new efficiency standard for Bitcoin mining hardware. This efficiency level helps maintain profitability during post-halving periods when block rewards decrease. Miners using the S23 series can sustain profit margins despite reduced mining rewards.

The model lineup addresses different operational needs. The air-cooled version provides accessible deployment, while the Hydro models deliver higher hashrates with reduced noise levels. The enterprise S23 Hydro 3U produces 1.16 PH/s for large-scale operations.
