Profitability Comparison
Bitmain Antminer L11 (20Gh)
Bitmain Antminer L9 (16Gh)
Based on BTC price of $78,165 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Bitmain Antminer L11 (20Gh) edges it: 2 of 5 factors go its way (efficiency, hashrate). Its biggest concrete edge: 25% more hashrate (0.0 vs 0.0 TH/s). The Bitmain Antminer L9 (16Gh) claws back ground on power consumption and home mining score and price-performance. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
The Bitmain Antminer L11 (20Gh) and Bitmain Antminer L9 (16Gh) diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Bitmain Antminer L11 (20Gh) 25% more hashrate (0.0 vs 0.0 TH/s)
- Bitmain Antminer L9 (16Gh) 9% better power draw (3,680 vs 3,360 W)
- Bitmain Antminer L11 (20Gh) 12% better efficiency (184,000 vs 210,000 J/TH)

- Bitmain Antminer L9 (16Gh) 20% more home mining score (30.0 vs 36.0)
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.
| Bitmain Antminer L11 (20Gh) | Metric | Bitmain Antminer L9 (16Gh) |
|---|---|---|
| $6,199 | Upfront cost (MSRP) | $3,199 |
| -$8.83 | Daily net profit | -$8.06 |
| -$9,422 | Net after 1 year | -$6,142 |
| -$12,646 | Net after 2 years | -$9,085 |
| -$15,869 | Net after 3 years | -$12,028 |
| 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.
