Profitability Comparison
Bitmain Antminer L9 (17Gh)
Elphapex DG 1+
Based on BTC price of $78,203 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Our scoring model gives the nod to the Bitmain Antminer L9 (17Gh), which leads on 3 of 4 weighted factors (efficacité, hashrate, consommation électrique). Its biggest concrete edge: 25% better efficacité (210,000 vs 280,000 J/TH). The Elphapex DG 1+ holds the edge in rapport qualité-prix. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
The Bitmain Antminer L9 (17Gh) and Elphapex DG 1+ diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Bitmain Antminer L9 (17Gh) 21% more hashrate (0.0 vs 0.0 TH/s)
- Bitmain Antminer L9 (17Gh) 9% better power draw (3,570 vs 3,920 W)
- Bitmain Antminer L9 (17Gh) 25% better efficacité (210,000 vs 280,000 J/TH)
- Bitmain Antminer L9 (17Gh) 26% better weight (13.5 vs 18.3 kg)
- Elphapex DG 1+ 10% more heat output (12,181 vs 13,375 BTU/hr)
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.
| Bitmain Antminer L9 (17Gh) | Metric | Elphapex DG 1+ |
|---|---|---|
| $3,380 | Upfront cost (MSRP) | $1,452 |
| -$8.57 | Daily net profit | -$9.41 |
| -$6,507 | Net after 1 year | -$4,885 |
| -$9,634 | Net after 2 years | -$8,319 |
| -$12,761 | Net after 3 years | -$11,753 |
| 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.
