The graphics card on a computer was once seen as largely immutable. Along with the CPU, these were some of the hardest components to swap out, and unlike with RAM or storage space, you were largely stuck with a “What you see is what you get” mentality. But new technology and the Thunderbolt 3 protocol have changed the market significantly.
While they can offer a significant boost for gaming, video editing, and other graphically intensive tasks, an eGPU isn’t cheap. But we’re here to help you navigate the market. Not only do we provide reviews for 10 of the best eGPU models in production today, but we also provide you with the knowledge you need to decide whether you need an eGPU and what qualities you should be paying attention to.

eGPU Buyer’s Guide
What is an eGPU? If you’ve made it through our review list and still find yourself confused, we’re here to help. We’ll start by breaking down the specifics of what exactly an eGPU is and who they’re best suited for then provide you with some information on what qualities you should pay the most attention to before we address some of the questions we hear most frequently.
eGPU stands for external graphics processing unit, and that’s largely self explanatory. An eGPU allows you to attach an external graphics card to your computer in the same way you would an external hard drive, and the enclosure provides all the cooling and power necessary to avoid drain from your laptop. So who would need this? Generally, an eGPU is an asset for gamers who want to play the latest AAA titles at the highest graphical settings and creative professionals working in highly detailed visual art, design, or video.
Any computer that needs to achieve graphical tasks outside the purview of their existing graphics card can benefit from an external graphics card, but these cool devices get the most mileage when connected to laptops. The compact design of laptops and the dramatic power usage required by a high end graphics card means that even high end gaming laptops are often behind the pack in terms of performance. An eGPU enclosure with a powerful chip like the Nvidia Geforce GTX 1070 setup will give you the juice you need without running the risk of frying your laptop’s components.
External graphics card enclosures come in two varieties: those that are just enclosures and require you to install your own GPU and those that come with a GPU pre-installed. The advantage of the latter is obvious: you get everything you need for a single price and don’t have to worry about installation. But being able to customize your GPU setup is one of the big advantages of a gaming box device.
Keep in mind whether the cards packed into a pre-built enclosure are capable of supporting all of your needs, and consider going bigger than what you precisely need. Investing in an RTX instead of a GTX, for instance, will future proof your computer for a while, and it’s important to keep in mind that you’ll only be getting about 90% of the max performance from cards with eGPUS than if you had cards installed directly inside your desktop.
The first thing to pay attention to when seeking out the best eGPU is whether or not the card you ultimately decide to use will work with your eGPU enclosure. If an eGPU doesn’t come with a graphics card already installed, most external graphics card manufacturers will reveal how much space there is for installing external graphics cards and also list the maximum wattage output the enclosure supports. If you want a decent card, we recommend the Nvidia GTX 1070, but investing in a new Nvidia RTX GPU will ensure that your computer is ready for cool new technologies like ray tracing and A.I. assisted rendering that represent the future of gaming technology.
One of the biggest problems of trying to pack a powerful GPU into a laptop is that it’s going to use a lot of power and run hot, requiring noisy fans that hog power. It stands the reason that an eGPU is going to face the same issues. That’s why it’s important to find a Thunderbolt enabled eGPU with a strong cooling system. Look for models that use a fan or multiple fans that are designed to run quiet but still provide you with the wattage that you need, and you should be fine.
GPUs are resource hogs, and that’s true whether it’s installed in your computer or connected via a Thunderbolt cable. Pay attention to the max wattage used by the eGPU version you’re looking for, but also be sure to pay close attention to the largest GPU wattage it supports. This will be one of the biggest factors in determining whether or not an eGPU can hndle the graphics cards that you want to use.
While the main reason for getting an eGPU product is that it allows you to establish an external graphics card connection with your laptop, that doesn’t mean that’s the only feature they offer. While the features listed below shouldn’t be your primary reason for purchasing an eGPU, they can push one over the edge if you’re comparing two models and can’t determine which is more worth your time based on a review alone.
- Additional ports are one of the most common inclusions in an eGPU, and they’re a useful one to have. Whether you’re talking about basic USB 3.0 ports or an ethernet port, they allow you to more readily connect your favorite gaming or work accessories, and they can be used for charging in a pinch.
- It’s pretty common for an eGPU enclosure to include its own RAM. This dedicated VRAM can further bolster your graphical performance and spare your computer’s internal memory the burden of having to do too much heavy lifting.
- Enclosures are essentially big power batteries at their source, and so it makes sense that most can double as an external battery for your computer. Many manufacturers will list the maximum watt output available for charging your laptop.
- Some enclosures can work double duty as a means for holding both a graphics card and a storage device for laptops. If you want an all in one solution, an enclosure that can also hold an SSD or HDD can be a huge asset.
Frequently Asked Questions
Is an eGPU Worth It?
That depends on your needs. While we suggest pulling the trigger and investing in a professional rig if you’re a serious gamer or a professional who needs a top shelf graphics card, an eGPU can serve as a great workaround, especially given the limited space available in notebook computers, and if you decide to build a new rig sometime in the future,, you can take the card out of most eGPU enclosures and use them in your new machine when it comes time for an upgrade.
How Do You Set Up an eGPU?
That’s going to vary from gaming box to gaming box. While some eGPUs are simply enclosures that require you to provide your own graphics cards, others come with Nvidia cards already built in. People who are uncomfortable about how to make their external GPUs run like they should might be best off looking for eGPUs like like the AORUS Gaming Box that come with their own cards and employ basic plug and play designs.
Do You Need Thunderbolt 3 for an External GPU?
Yes. For a quality graphics card like the Nvidia GTX to work properly, it needs some pretty quick data transfer, and the only technology capable of accomplishing that right now is what you get through a Thunderbolt 3 port. Until a data transfer process that can compete comes around, you’re going to need a computer that supports a Thunderbolt 3 port to get reasonable usage out of an eGPU enclosure or the Nvidia graphics card you might want to use with it.
If you want to get powerful graphical performance without having to invest in new laptops entirely (and you have a compatible Thunderbolt 3 port), an eGPU gaming box can be one of the best ways to game or engage in high level video editing. While these devices aren’t perfect, they offer you to keep your laptop portable without giving up on the option for high-power graphical performance. This technology may be new, but the models we’ve presented here represent the best of the best. If you decide you want to invest in an external GPU enclosure, be sure to check out our guide to the best GPUs, so you can find a comparable card that’s well suited to your needs.
