2026 Buyer's Guide: Antminer S23 (318 TH/s) – power, efficiency and profitability
Bitmain is poised to mark a new milestone in the history of Bitcoin mining with the arrival of the Antminer S23 (318 TH/s)expected in the first quarter of 2026. This model succeeds the generation S21Already known for its excellent power-to-consumption ratio, this new machine is the Minent.fr guide to understanding what it truly means for professional miners.
🚀 A new generation of SHA-256 ASICs
THE Bitmain Antminer S23 uses the latest architecture SHA-256 Optimized for 4nm etching, offering unprecedented energy density in a compact form factor. With a hashrate of 318 TH/s for a consumption of approximately 3498 W, THE S23 displays a record energy efficiency of ≈11 J/TH, compared to 16 J/TH for the S21 classic.
- Hashrate : 318 TH/s ±3%
- Consumption : 3498 W ±5%
- Efficiency : ≈11 J/TH
- Algorithm: SHA-256
- Cooling: Air (4 high-efficiency fans)
- Weight : approximately 14.5 kg
- Noise level: ≈75 dB
This advance positions the S23 as one of the most efficient and cost-effective Bitcoin miners on the market.
⚙️ Performance: efficiency and stability
Thanks to its energy efficiency of approximately 11 J/TH, THE S23 allows for more calculations to be performed for the same amount of electricity. This represents up to 30 to 40% energy savings compared to a S19K Pro, and about 25% compared to a S21.
Under optimal conditions (fresh air, stable 220V, official Bitmain firmware), the S23 maintains a stable hashrate around 318 TH/s with minimal variation. It is designed to operate 24/7, even in high-density farms, with better thermal tolerance than previous generations.
📊 Comparatif S21 vs S23
| Model | Hashrate | Consumption | Efficiency (J/TH) | Cooling | Exit |
|---|---|---|---|---|---|
| Antminer S21+ | 216 TH/s | 3564 W | 16.2 | Air | 2024 |
| Antminer S21 Hydro | 358 TH/s | 5360 W | 15.0 | Hydro | 2025 |
| Antminer S23 | 318 TH/s | 3498 W | ≈11.0 | Air | 2026 |
➡️ The S23 displays superior performance while maintaining air cooling, making it simpler to install than the Hydro or Immersion models.
💰 Profitability and return on investment
At an estimated price between €5,000 and €6,000 according to the first retailers, the S23 falls within the same range as the S21 upon its release. Thanks to its low consumption (≈3.5 kW), it allows for maintaining low operating costs even with an electricity tariff higher than €0.10/kWh.
The return on investment (ROI) will depend on the price of Bitcoin and network difficulty, but current projections show a ROI between 8 and 12 months at constant production.
🔋 Installation and maintenance tips
- Install the miner in a well-ventilated space (ideally <30°C).
- Provide a suitable circuit breaker and a dedicated power line (200–240 V AC).
- Clean the fans and filters regularly to prevent overheating.
- Update the Bitmain firmware as soon as it is officially available to improve stability and efficiency.
