Profitability Comparison
Bitmain Antminer L11 (20Gh)
FluMiner L3
Based on BTC price of $78,241 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Weighing six performance factors, the FluMiner L3 comes out ahead — it takes 5 of 6 (efficacité, consommation électrique, score de minage domestique, niveau sonore, rapport qualité-prix). Its biggest concrete edge: 54% better power draw (3,680 vs 1,700 W). The Bitmain Antminer L11 (20Gh) holds the edge in hashrate. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
Stripped to the numbers, this is how far apart the Bitmain Antminer L11 (20Gh) and FluMiner L3 sit on each measurable spec:
- Bitmain Antminer L11 (20Gh) 111% more hashrate (0.0 vs 0.0 TH/s)
- FluMiner L3 54% better power draw (3,680 vs 1,700 W)
- FluMiner L3 3% better efficacité (184,000 vs 178,947 J/TH)
- FluMiner L3 33% better noise (75.0 vs 50.0 dB)
- Bitmain Antminer L11 (20Gh) 116% more heat output (12,556 vs 5,800 BTU/hr)
- FluMiner L3 87% more score de minage domestique (30.0 vs 56.0)
Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| Bitmain Antminer L11 (20Gh) | Metric | FluMiner L3 |
|---|---|---|
| $6,199 | Upfront cost (MSRP) | $2,849 |
| -$8.83 | Daily net profit | -$4.08 |
| -$9,422 | Net after 1 year | -$4,338 |
| -$12,646 | Net after 2 years | -$5,827 |
| -$15,869 | Net after 3 years | -$7,316 |
| 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.
