Laptop technology is evolving fast to surpass legacy desktop computers. Now, you can distinctly observe the stark difference between the two. However, even with all the development, it is still quite impossible to just replace or upgrade your laptop components, like you would do on a desktop.

Even so, there’s hope for a breakthrough. But, in the meantime, you can use “MXM” modules to upgrade your laptop. You can use the modules to replace the old components with better processing performance, energy-efficiency, and advanced graphics.

This is particularly beneficial to laptop users looking to swap their existing GPUs with newer and improved models.

Aside from the “MXM” modules being relatively expensive, they are also not always compatible with all laptops. Hence the introduction of external GPU enclosures.

What Is an External GPU Enclosure?

An external GPU enclosure is very similar to a computer. It has its power source, cooling fans, and PCIe slots for the GPU cards. These tiny enclosures are designed to enable you to hook up your new and upgraded GPU to your laptop. And all you will need for this is a Thunderbolt 3 port.

Below, we discuss 7 of the best eGPU enclosures that best suit your needs:

  • Razer Core X
  • Razer Core X Chroma
  • AORUS/Gigabyte Gaming Box
  • Sonnet Breakaway 550
  • ASUS XG Station 2
  • AKiTiO Node Titan
  • Sapphire GearBox

How Do External GPUs Work?

An eGPU is an external enclosure for a desktop-style video card that can plug into a laptop or other systems to boost its graphical performance.

How does it do that?

Equipped with a power supply, a cooling system, a PCI slot, a card, and perhaps other kind of hardware, it facilitates your laptop’s transformation into a gaming powerhouse. Thus giving you the ability to upgrade via an external solution rather than purchasing a new laptop.

These external GPU enclosures are also equipped with a different compatibility system. Therefore, you have to acquire the right laptop and Thunderbolt 3 USB cable to ensure a smooth video stream.

What Makes Them Efficient and Reliable?

Their highly parallel structure makes them efficient vis-a-vis the general-purpose central processing unit(CPU) for algorithms that process large data blocks in parallel. They majorly use their transistors to do calculations related to 3D computer graphics.

With basic 2D acceleration and framebuffer capabilities, this eGPU ensures compatibility with your gaming equipment that provides efficiency and higher compatibility.

How Can you Boost the Graphical Design?

External GPU enclosures have developments like the programmable shaders, which manipulate vertices and textures, oversampling and interpolation techniques. These features reduce aliasing and enhance very high precision color spaces that give mesmerizing and admirable results

Why You Need the External GPU

Most GPUs have graphic cards that record high definition videos on the card, offloading the central processing unit with the task. With fewer tasks to perform, the CPU increases the speeds with which it performs its assigned, high-priority duties. Hence accelerating the motion compensation decoding process commonly known as mocomp

What You Need to Know About eGPU Enclosures

As mentioned before, external GPU enclosures are like small computer cases. But unlike computers, they are solely made to hold graphics cards and nothing else. Some are compact, meaning you can’t change the GPU inside, while others are not.

There are two types of external GPU enclosures:

I. Portable, but not mobile

These external GPU enclosures are made to sit on a desk. Since they double as laptop docks, they have additional IO interfaces such as USB ports and hard drive bays. When connected to the laptop, they access all data, meaning you can attach an extra display or peripheral device.

II. Integrated design

These enclosures have docking features. Also, they are light, such that you can easily fit them into your bag to go. Usually, they come with an already existing GPU card and are hard to upgrade.

Understanding Thunderbolt 3

Have you ever noticed how graphics cards are fixed directly to the motherboard and not through cables?

Well, while USB 3.1 is sufficient for broad bandwidth needs, it was not enough to fully serve a high-speed GPU. Therefore, there was a need to find better technology to help introduce external GPUs to laptops

The whole idea of external GPUs to use with laptops came to life with the Thunderbolt 3 technology. These cables and ports made it possible to connect your computer to an external GPU. The Thunderbolt 3 allows for a large enough bandwidth to cater to the hungry GPU needs.

Before you buy an external GPU enclosure, make sure you verify that the computer not only has a Thunderbolt 3 port but is also compatible with your GPU’s operations.

After you have confirmed that they have a Thunderbolt 3 port compatible with your computer, consider the GPU’s performance.

Performance of the GPU

When choosing an external GPU enclosure, the search boils down to the performance of the GPU. How much loss occurs when you connect the GPU? How is the performance affected by connecting the eGPU using a Thunderbolt 3 board rather than connecting it directly to the motherboard?

On average, you will experience a 10-15% drop in performance, but this varies depending on the card you use. However, even with this drop, the external GPU is faster than an internal GPU due to drive optimization.

Matching your CPU and GPU

One crucial point to consider when buying an external GPU enclosure is compatibility between your new addition and the CPU. Remember that the computer’s CPU plays an essential part in the operation of your GPU.

The CPU will always be the one to receive instructions and send them to the GPU. So, without proper communication between these two components, you are bound to encounter problems. And no matter the speed capabilities in your GPU, a slow CPU will always slow you down.

When you decide to get an external GPU, make sure it is compatible and works at the CPU’s best rate. i.e., If you have a lower-end CPU in your laptop, invest in a mid-range GPU for optimal performance.

Display support

Pairing your computer, external GPU, and a display go hand in hand. For a high-performance GPU, you need a high-end CPU and an appropriate display.

An external GPU enclosure comes with the ability to connect with a wide range of displays. However, this is not always necessary.

And since your laptop has its display, you can forego an additional connection, which often reduces your setup performance.

But if you need a display, keep in mind the optimal solution you can employ without affecting your performance.

Power and cooling

External GPU enclosures are self-sufficient. That means they have their power supply and cooling units.

When buying a GPU enclosure, you want to choose one that provides enough power to cater to the GPU’s needs and has a reliable cooling system to dissipate the heat generated during use.

Dimensions of different enclosure differ. You will find one with a large space that can accommodate several cooling fans, while others use one.

Heat is one of the worst enemies of performance and durability. A GPU that remains hot for the better part of the day is bound to fail in no time. Also, you notice your performance dropping with every degree increase.

That is why you must choose an enclosure that serves your performance needs and takes care of your heat problem.

Now, there is another problem. Some external GPU enclosures have their fans running non-stop, which means more power requirements. Others are so loud from the constant vibrations of the motor and casings.

Before you settle for a GPU enclosure, be sure to read and watch reviews online to determine if you get the excellent, inaudible type of buzzing fans.

You can find this information on the spec sheet of the product you intend to buy.

Find an external GPU enclosure that has the juice to keep your system running smoothly.

Modifications

When buying an eGPU enclosure, most users want a sleek, elegant, plug-and-use kind of device. And most of the time, that is what you get. Now, suppose you find the perfect GPU, but you feel the need to tweak an aspect of your enclosure.

Maybe you want to import a Thunderbolt 3 slot and use an old graphics card. You should be able to access the components of your enclosure to make replacement easy for you.

So, you should avoid the tiny GPU enclosure that does not let you reach the GPU slot and go for one that allows for more straightforward modification.

Proprietary Connections and Docking Features

Before swiping your credit card to pay for an external GPU enclosure, always ensure that you have triple checked the compatibility. This is because, despite most enclosures using thunderbolt 3, others are still in the USB-C era.

But, if you find one with both, the better. That means you can use the external GPU enclosure as a docking station for other components such as monitors, mouse, keyboard, and speakers.

If your laptop allows for it, you could even use the Thunderbolt 3 slot to charge it.

When buying an external GPU enclosure, keep in mind your power requirements, the enclosure’s size, support, cooling, and ports available for integration.

Limitations of eGPU enclosures

We have discussed how external graphic processing units work and which of them are the best. However, there are some drawbacks associated with the use of eGPUs that you should know about before buying one:

(i) External performance is not optimal

External GPU enclosures give you the chance to enjoy your laptop as a desktop computer, with added advantages. However, an external GPU’s performance cannot be compared to that of an internally mounted graphics card.

After testing, there is an estimated 15% drop in performance when you use an external GPU. Although it is not that big of a deal, since the GPUs can sufficiently serve your speed needs, it is still a limitation associated with the use of external GPU enclosures.

(ii) External GPU Enclosures are expensive

A GPU dock is one of the smallest pieces you will find on your laptop’s motherboard. But that is not to mean that it will be the cheapest.

Now, imagine having to buy a GPU and enclosure, connecting cables, and a compatible port with your laptop. And on top of the GPU, you buy a dock. For this, you have to choose one that is compatible with your computer, making your options very limited, in terms of prices and variety.

By the time you have everything you need, you will have a dent in your wallet.

It is a worthy investment because you immediately notice a change in performance and speed when working or gaming with your laptop.

(iii) A lot of research goes into the purchase

Buying products is now more accessible. Some platforms allow you to buy any product from the comfort of your home. However, this should not be any reason to get a sub-standard product that does not suit your needs.

Before ordering an external GPU enclosure, take some time to determine the type of laptop you have and compatible GPUs. Once you have the details about the CPU, I/O interfaces, and the graphics cards you can use, move on to the product.

Please find out more about the specifications of the external GPU enclosure before you buy it.

Although you spend some time doing so, you will be happier with your purchase if it is the one you wanted.
