Antminer L11: Vnish Firmware, Specifications, and Profitability

What is the Bitmain Antminer L11?

The Bitmain Antminer L11 is a new generation of ASIC miners for the
Scrypt algorithm. Unlike the popular Bitcoin miners from the S series, L11 devices are aimed
primarily at mining Litecoin and Dogecoin. In addition, thanks to the features of Scrypt, combined
mining of LTC and DOGE is possible, so profitability shouldn’t be evaluated based on a single coin alone.

At the same time, the L11 series is interesting not only for its increased hashrate. Bitmain is simultaneously developing
several versions of the device: from the air-cooled Antminer L11 at 20 GH/s to significantly more
powerful hydro-cooled models. In other words, the name “L11” actually covers an entire lineup
of ASICs with different power, cooling, and hosting requirements.

What Antminer L11 models are available?

Right now several name variants of the L11 come up most often. Because of this, search queries often include
Antminer L11 20, L11 20G, L11 Pro,
L11 HU2, or L11 Hyd 6U. However, it’s important to understand: these are not the same device.

Comparing Antminer L11 models by hashrate and power draw

The figures shown are typical specifications for each model. Actual hashrate and power draw
depend on the specific unit and operating conditions.

Antminer L11 20G: what does 20,000 MH mean?

One of the most common queries is Antminer L11 20G, L11 20,000 MH
or simply L11 20. These all refer to the same base model with a hashrate of around
20 GH/s.

It’s easy to get confused by the units here. 1 GH/s = 1000 MH/s, so
20 GH/s = 20,000 MH/s. If you see the labels L11 20G, L11 20 GH/s, or L11 20,000 MH/s
in a store or calculator, these are usually just different ways of writing the same
performance class.

Antminer L11 Pro — a small name change, a noticeable difference

The Antminer L11 Pro outwardly belongs to the same air-cooled lineup, but its specifications
differ from the base L11. Hashrate is around 21 GH/s, and rated power draw is
around 3612 W.

At first glance, the difference between 20 and 21 GH/s looks small. But with round-the-clock ASIC operation,
raw speed isn’t the only thing that matters. Lower power consumption combined with a slightly higher hashrate means
better energy efficiency: roughly 172 J/GH versus 184 J/GH for the base L11.

Consequently, when buying it makes sense to compare not just the price of the device itself, but also the cost
per GH/s, power draw, and electricity rate. Sometimes a more expensive model turns out to be more attractive
precisely because of the electricity costs over its entire operating life.

Antminer L11 Hyd 6U 33 GH: where serious power begins

The Antminer L11 Hyd 6U is already an entirely different class of hardware. This version uses
hydro cooling and delivers around 33 GH/s at a power draw of about 5676 W.
Efficiency is around 172 J/GH.

The main advantage of Hydro isn’t just hashrate. Liquid cooling dissipates heat more effectively
and noticeably reduces noise levels compared to powerful air-cooled ASICs. For a mining
farm, that can matter far more than a few extra percentage points of performance.

But there’s a downside too: the L11 Hyd 6U requires appropriate infrastructure.
This kind of ASIC is intended primarily for professional hosting, where power, cooling,
racks, and maintenance are already planned for.

And what is the Antminer L11 HU2?

The Antminer L11 HU2 is an even more powerful hydro-cooled version with a hashrate of around
35 GH/s. At a power draw of around 5775 W, its efficiency is
approximately 165 J/GH, meaning it’s more efficient than both the base L11 and the L11 Hyd 6U in terms
of hashrate relative to power consumed.

That’s exactly why, when choosing between the L11, L11 Pro, L11 Hyd 6U, and L11 HU2, you can’t go
by the GH/s figure alone. The more powerful the ASIC, the more the electricity cost and the cost of the whole
infrastructure matter.

Antminer L11: profitability — how much can it actually earn?

One of the most popular queries is Antminer L11 profitability. It’s important to
keep in mind here: an ASIC doesn’t have a fixed “daily income” figure. Profitability changes along with LTC and DOGE
prices, network difficulty, total network hashrate, pool fees, and electricity cost.

Accordingly, the number a calculator shows today may look completely
different a week from now. This is especially noticeable with Scrypt miners, since changes in the price of Dogecoin or Litecoin
directly affect mining economics.

What the final profit depends on

For Scrypt mining, combined mining is also worth taking into account. With the right pool
setup, the same computing resource can be used to earn rewards tied
to both Litecoin and Dogecoin. That’s why a profitability calculator is best thought of as a tool
for comparing scenarios rather than a promise of fixed earnings.

How much electricity does the Antminer L11 consume?

Electricity is one of the most important factors when choosing an L11. Even a difference of a few hundred watts
adds up to a noticeable amount over a year if the ASIC runs 24 hours a day.

*Calculated for continuous 24/7 operation at rated power consumption. Actual values
may vary.

For example, the base L11 at 3680 W consumes about 88.3 kWh per day.
Over 30 days that’s roughly 2650 kWh. Accordingly, if electricity costs
$0.10 per kWh, energy alone would cost around $265 per month, and at a rate of $0.05, about $132.5.

That’s exactly why the question “how much does the Antminer L11 earn?” without specifying the electricity cost is practically
meaningless. The same ASIC can be attractive for industrial-scale mining with cheap
electricity and completely unappealing at an expensive residential rate.

Why does the Antminer L11 need Vnish firmware?

A modern ASIC is no longer just a set of chips. Software control of the device plays an important role:
temperature, frequencies, voltage, fans, stability, and hashrate control.

This is exactly where interest in Vnish for the Antminer L11 comes in. For an ASIC owner, firmware
isn’t just a way to change one number in the interface. Good firmware should make it possible
to manage hardware more effectively and choose an operating mode suited to specific farm conditions.

For one miner, the priority might be maximum hashrate, while for another minimum
power consumption matters more. A third might aim for a balance between temperature, stability, and efficiency.
This becomes especially noticeable on large farms, where even a small change in parameters across hundreds
of devices translates into a significant difference in electricity consumption.

What will be especially interesting for L11 owners?

The arrival of Vnish for this new generation of ASICs is especially interesting because the L11 series differs noticeably
from previous generations of Scrypt hardware. There are both air-cooled models and powerful hydro-cooled
ones, which means device management requirements matter even more.

At the same time, what matters to a miner isn’t a record figure held for a few minutes, but a mode in which the hardware
can run stably for months. After all, temperatures, power draw, hashrate stability, and ASIC behavior
under sustained load directly affect the farm’s economics.

That’s exactly why the development of alternative firmware for the Bitmain Antminer L11 is an important
event for owners of this generation of devices. The more control tools an operator gets,
the easier it is to tune the mode to a specific electricity cost and the mining site’s goals.
