Profitability Comparison
Antminer L7
Antminer L9
Based on BTC price of $78,095 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Bitmain's two most powerful Scrypt miners. The L7 set a high bar, and the L9 aims to push Scrypt mining efficiency further.
The L9 brings improved efficiency to Scrypt mining, though the gap is narrower than the L3+ to L7 leap. The L7 remains competitive and can be found at better prices on the secondary market.
Spec Deltas
Stripped to the numbers, this is how far apart the Antminer L7 and Antminer L9 sit on each measurable spec:
- Antminer L9 77% more hashrate (0.0 vs 0.0 TH/s)
- Antminer L9 2% better power draw (3,425 vs 3,360 W)
- Antminer L9 45% better efficiency (378,453 vs 210,000 J/TH)
- Antminer L7 3% better weight (14.4 vs 14.8 kg)
- Antminer L7 2% more heat output (11,686 vs 11,464 BTU/hr)
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.
| Antminer L7 | Metric | Antminer L9 |
|---|---|---|
| $4,500 | Upfront cost (MSRP) | $6,500 |
| -$8.22 | Daily net profit | -$8.06 |
| -$7,500 | Net after 1 year | -$9,443 |
| -$10,500 | Net after 2 years | -$12,386 |
| -$13,501 | Net after 3 years | -$15,329 |
| 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.

Frequently Asked Questions
Should I upgrade from an L7 to an L9?
The efficiency improvement is meaningful but incremental. Upgrade calculations depend on your electricity cost and the price difference between the two units.
Are both SHA-256 miners?
No. Both the L7 and L9 are Scrypt algorithm miners, primarily used for mining Litecoin and Dogecoin.
