Spec Deltas
The Bitmain Antminer L11 Pro (21Gh) and Elphapex DG2+ diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Bitmain Antminer L11 Pro (21Gh) 2% more hashrate (0.0 vs 0.0 TH/s)
- Bitmain Antminer L11 Pro (21Gh) 7% better power draw (3,612 vs 3,900 W)
- Bitmain Antminer L11 Pro (21Gh) 10% better efficiency (172,000 vs 190,244 J/TH)
- Elphapex DG2+ 8% more heat output (12,324 vs 13,307 BTU/hr)
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.
| Bitmain Antminer L11 Pro (21Gh) | Metric | Elphapex DG2+ |
|---|---|---|
| $7,999 | Upfront cost (MSRP) | $8,000 |
| -$8.67 | Daily net profit | -$9.36 |
| -$11,163 | Net after 1 year | -$11,416 |
| -$14,327 | Net after 2 years | -$14,832 |
| -$17,491 | Net after 3 years | -$18,248 |
| 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.
