The Antminer L9 is Bitmain’s flagship Scrypt miner and the direct successor to the long-running L7. At around 16 GH/s and 0.21 J/MH, it nearly doubles the L7’s output while improving efficiency.

The merged-mining advantage

Scrypt’s defining feature is merged mining: one machine secures both the Litecoin and Dogecoin networks at full hashrate, earning rewards from both chains simultaneously with no extra power cost. That dual income stream is a big part of the L9’s appeal — and something Bitcoin’s SHA-256 machines can’t do. See ASIC miners explained for how algorithms shape this.

L9 vs. L7

The Antminer L7 defined Scrypt mining for years at ~9.5 GH/s and ~0.35 J/MH. The L9 roughly doubles the hashrate and cuts energy per megahash by around 40%, which is what keeps it profitable at difficulty levels where the L7 starts to struggle.

The upgrade logic

If you’re running L7s and your power isn’t free, the L9’s efficiency usually wins on total cost of ownership as Scrypt difficulty rises.

Hosting the L9

At ~3,360 W, the L9’s returns are driven by electricity cost, just like any modern ASIC. A facility on cheap renewable power protects your margin — the same logic we lay out in self-mining vs. hosting. Run yours with our mining hosting, or buy one in the marketplace.

Frequently asked questions

What coins does the Antminer L9 mine?

Scrypt coins — primarily Litecoin and Dogecoin, which it mines together via merged mining at full hashrate on both chains.

How much better is the L9 than the L7?

The L9 delivers roughly double the hashrate (~16 GH/s vs ~9.5 GH/s) and about 40% better efficiency (~0.21 vs ~0.35 J/MH).

Does merged mining cost extra power?

No. Mining Litecoin and Dogecoin together draws the same power as mining one of them — you simply earn rewards from both chains at once.
