Profitability Comparison
Antminer D9
Antminer KS5
Based on BTC price of $78,139 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Antminer KS5 edges it: 3 of 6 factors go its way (efficiency, hashrate, price-performance). Where it pulls away hardest is 1030% more hashrate (1.8 vs 20.0 TH/s). That said, the Antminer D9 isn't beaten everywhere — it still wins power consumption and home mining score and noise level. Review the detailed specs and profitability calculations above to determine which miner best fits your specific setup.

Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Antminer D9 | Metric | Antminer KS5 |
|---|---|---|
| $3,000 | Upfront cost (MSRP) | $12,000 |
| -$6.75 | Daily net profit | -$6.48 |
| -$5,464 | Net after 1 year | -$14,366 |
| -$7,927 | Net after 2 years | -$16,731 |
| -$10,391 | Net after 3 years | -$19,097 |
| 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.
