Profitability Comparison
Antminer D9
Antminer KS5 Pro
Based on BTC price of $78,139 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Based on our multi-factor analysis, the Antminer KS5 Pro wins on 3 of 4 factors (efficiency, hashrate, price-performance). Where it pulls away hardest is 1086% more hashrate (1.8 vs 21.0 TH/s). That said, the Antminer D9 isn't beaten everywhere — it still wins power consumption. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.

Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Antminer D9 | Metric | Antminer KS5 Pro |
|---|---|---|
| $3,000 | Upfront cost (MSRP) | $15,000 |
| -$6.75 | Daily net profit | -$6.80 |
| -$5,464 | Net after 1 year | -$17,484 |
| -$7,927 | Net after 2 years | -$19,968 |
| -$10,391 | Net after 3 years | -$22,451 |
| Does not pay back at current rates (negative daily profit) | Payback period | Does not pay back at current rates (negative daily profit) |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
