The 5 Best External Graphics Card Enclosures

Need a performance boost? You can now experience the power of a cutting-edge gaming PC, with 240 FPS and stunning graphics, using your current rig. How? Anything is possible with one of the best external graphics cards.

The best external graphics cards connect to your laptop (or desktop) to provide the same benefits as a dedicated GPU. That means fantastic resolution, multi-monitor support, and VR-ready quality–all in one portable & convenient package. Whether you’re on a two-year-old laptop or an aging desktop, there’s no need to settle for anything less than the best.

This article takes you through the five best external GPUs and eGPU enclosures on the market. We’ll also walk you through the technology to help you find the perfect fit for your rig. Ready for top-tier graphics? Let’s get started.

What to Look for in an eGPU

An external graphics card is a dedicated GPU that connects to your computer via a specialized enclosure or eGPU case. These enclosures house the graphics card and feature the technology necessary to connect it to your machine and boost its graphical capabilities.

External graphics cards are typically used for laptops, but they’re also ideal for desktop users whose motherboards can’t handle a GPU, whether that be for compatibility issues or a lack of space.

As you’d expect, external graphics cards come in many shapes, sizes, and styles. But no matter what your reasons for grabbing one, there are three primary considerations when choosing an external GPU.

1. Graphics Card
The term ‘external graphics card’ is something of a misnomer. The fact is that most external graphics cards are the same ones you’ll find within popular gaming rigs, e.g., GPUs from NVIDIA and AMD.

So what makes external graphics cards unique? Their enclosures.

Naturally, external GPU enclosures vary in features. The primary difference between models is whether or not they come with a graphics card out of the box. If so, you’re good to go (as long as the enclosure is compatible with your device–see below).

If not, you’ll need to purchase the enclosure, as well as an NVIDIA GeForce or AMD Radeon graphics card to put inside it.

2. Compatibility
All modern external graphics cards share one thing in common–they connect to your rig using Thunderbolt 3 technology. That’s because Thunderbolt 3 boasts transfer speeds up to 40GB/s. These high speeds are crucial to ensuring the proper functioning of today’s high-powered graphics cards.

But despite their shared technology, not all external graphics cards are universally compatible. Some only work with PCs and others with Macs. Only a handful of top-tier models feature the necessary drivers to work with all types of builds.

3. Specifications
There are tons of high-end eGPU brands competing for your business. As such, you’ll find eGPU enclosures that boast portable form factors, LEDs, slick cooling systems, and more. Each model features a unique spec sheet to woo you towards that buy button.

Compare your favorite models carefully before making a final decision. To make the process easier, we’ve outlined the major specs, pros, and cons of each model. Let’s check ‘em out.
