|---|---|---|
| Hashrate | 500 TH/s | 335 TH/s |
| Power Consumption | 5500 W | 5360 W |
| Energy Efficiency | ≈ 11.0 J/TH | ≈ 16.0 J/TH |
| Cooling Method | Liquid Hydro-Cooling | Liquid Hydro-Cooling |
| Voltage Requirement | 380–415V, 3-Phase | 380–415V, 3-Phase |
| Best Use Case | High-density professional mining farms; maximize ROI and energy savings | Medium-to-large mining setups seeking stable hydro cooling |
| Overall Performance | Flagship-class performance with top-tier efficiency | Strong performance, but less efficient than XP+ Hyd |
The Antminer S21 XP+ Hyd delivers substantially higher performance and energy efficiency than the standard S21 Hyd, making it the better choice for large-scale farms focused on maximizing ROI and reducing electricity cost per terahash. Meanwhile, the S21 Hyd provides hydro-cooling stability at a more accessible price point, suitable for medium-sized mining operations.
