Profitability Comparison
Antminer D9
Bitmain Antminer Z15
Based on BTC price of $78,066 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Bitmain Antminer Z15 edges it: 4 of 6 factors go its way (efficiency, hashrate, power consumption, price-performance). Where it pulls away hardest is 100% better efficiency (1,604.0 vs 3.6 J/TH). That said, the Antminer D9 isn't beaten everywhere — it still wins home mining score and noise level. Review the detailed specs and profitability calculations above to determine which miner best fits your specific setup.
Spec Deltas
The Antminer D9 and Bitmain Antminer Z15 diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Bitmain Antminer Z15 23629% more hashrate (1.8 vs 420.0 TH/s)
- Bitmain Antminer Z15 47% better power draw (2,839 vs 1,510 W)
- Bitmain Antminer Z15 100% better efficiency (1,604.0 vs 3.6 J/TH)

- Antminer D9 88% more heat output (9,687 vs 5,152 BTU/hr)
- Antminer D9 29% more home mining score (36.0 vs 28.0)
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 | Bitmain Antminer Z15 |
|---|---|---|
| $3,000 | Upfront cost (MSRP) | $998 |
| -$6.75 | Daily net profit | $11.46 |
| -$5,464 | Net after 1 year | +$3,186 |
| -$7,928 | Net after 2 years | +$7,371 |
| -$10,391 | Net after 3 years | +$11,555 |
| Does not pay back at current rates (negative daily profit) | Payback period | Pays for itself in ~87 days at current rates |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
