Bitmain Antminer L11 (20GH)

Bitmain Antminer L11 — Latest Generation for Scrypt Mining (LTC & DOGE)

‍

The Bitmain Antminer L11 is currently the latest generation of Scrypt ASIC miners from Bitmain. Developed for mining Litecoin (LTC) and Dogecoin (DOGE), the L11 offers computing power of around 20 GH/s (± 5%) with a power consumption of 3680 watts — which corresponds to an energy efficiency of around 184 J/GH.

‍

The L11 series is currently Bitmain's most efficient air-cooled scrypt mining hardware and uses proven technology with optimized power density.

Technical Classification and Performance Data

The Antminer L11 calculates based on the Scrypt algorithm and is completely designed for merged mining. Litecoin and Dogecoin can be mined in parallel — without additional power consumption, without additional hardware.

‍

Performance data at a glance:
• Computing power: approx. 20 GH/s (± 5%)
• Power consumption: approx. 3680 W
• Energy efficiency: approx. 184 J/GH
• Algorithm: Scrypt (for Litecoin & Dogecoin)
• Merged mining: natively supported
• Cooling: air-cooled
• Connection: Ethernet/ bitmain interface

‍

The high hashrate and low energy consumption make the L11 currently the most powerful and efficient generation within the Bitmain Scrypt series.

Development of the Bitmain Scrypt series: L7 → L9 → L11

The L11 is the current top model in Bitmain's long-standing Scrypt Miner series. It is the third stage of evolution:
• Antminer L7 (9.5 GH/s): First scrypt model from Bitmain. Known for long profitability and very stable mileage.
• Antminer L9 (15—17 GH/s): Optimized successor model with higher hashrate and improved efficiency — still a popular all-rounder today.
• Antminer L11 (20 GH/s): Latest generation with further improved energy efficiency and higher hashrate — with strong stability.

‍

The new generation is also available in two other versions:
• Antminer L11 Pro (21GH/s) — with higher hashrate with classic air cooling
• Antminer L11 Hydro (33GH/s) — water-cooled for maximum performance and thermal stability

‍

Professional miners regard the L series as one of the most reliable product lines in the ASIC market — known for robust continuous operation, long-term profitability and a sophisticated hardware structure.

Cooling, Design and Operation

The Antminer L11 continues to rely on classic air cooling with optimised air flow. The cooling is designed for continuous operation, without complex additional infrastructure. The compact design complies with well-known bitmain standards and integration into existing setups is easy.
• Classic Bitmain chassis with four temperature-controlled fans
• Robust aluminum chassis for industrial use
• Integrated control system via Ethernet and web GUI
• Minimal maintenance with regular cleaning

Note about older models

Earlier models such as the Antminer L7 or the L9 are sometimes no longer available at Cryptohall24 or are gradually being removed from the range. They were replaced by more powerful variants such as the L11.
