Profitability Comparison
Antminer D9
Antminer S19j
Based on BTC price of $78,185 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Antminer S19j edges it: 4 of 5 factors go its way (efficacité, hashrate, score de minage domestique, rapport qualité-prix). Where it pulls away hardest is 4985% more hashrate (1.8 vs 90.0 TH/s). That said, the Antminer D9 isn't beaten everywhere — it still wins consommation électrique. Review the detailed specs and profitability calculations above to determine which miner best fits your specific setup.
Spec Deltas
The Antminer D9 and Antminer S19j diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":

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 S19j |
|---|---|---|
| $3,000 | Upfront cost (MSRP) | $2,000 |
| -$6.75 | Daily net profit | -$4.20 |
| -$5,464 | Net after 1 year | -$3,534 |
| -$7,927 | Net after 2 years | -$5,067 |
| -$10,391 | Net after 3 years | -$6,601 |
| 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.
