| Rank | Model | Coin | Power | Profit per Watt | Net Daily Profit |
|---|---|---|---|---|---|
| 1 | Bitmain Antminer Z15 PRO (840Kh/s) | ZEC | 2,780 W | $0.010132/W·day | $28.17 |
| 2 | Bitmain Antminer D9 (1770Gh/s) | DASH | 2,839 W | $0.004512/W·day | $12.81 |
| 3 | Bitmain Antminer Z15 (420K) | ZEC | 2,780 W | $0.003866/W·day | $10.75 |

Key Insights for July 2026
- Hydro-cooled S23 series dominate Bitcoin mining efficiency on CoinWarz, delivering the best profit per watt among SHA-256 miners thanks to excellent hashrate-to-power ratios.
- At $0.10/kWh, top models remain profitable while many older or less efficient units show negative returns.
- Profit per watt is the most reliable indicator of long-term viability, as it directly accounts for electricity costs, the largest ongoing expense.
- Altcoin miners (ZEC, DASH, LTC/DOGE) currently lead the absolute rankings due to favorable market conditions.
Recommendations
For Bitcoin miners: Prioritize hydro-cooled Antminer S23 Hyd and S21 XP+ Hyd models for maximum efficiency and profit per watt.
For maximum overall return per watt: Consider the Antminer Z15 PRO if you can mine ZEC.
