The 6 Best External GPU’s

It’s no secret that laptops, even the latest gaming ones, will always fall short in terms of graphical processing power when compared to desktop computers. External graphics processing units, or eGPUs, are a great way to give your gaming laptop a boost by allowing it to provide superior graphics from a more powerful source. Buying the right external GPU means finally being blown away by visuals thanks to better frame rate, higher resolutions, and more.

Why buy an external GPU?

For the longest time, laptop users had to accept the fact that they’re sacrificing horsepower for mobility. While desktop gamers had different options for enhancing their specs, people using laptops to play games or use demanding software had little choice other than to buy a new machine if they hoped to keep up. Suffice to say, it was hard to take laptop gamers seriously since their machine would be unable to play the latest titles efficiently in no time.

Today, external GPUs offer an alternative source of power so you can continue gaming on your laptop for years to come. Thanks to the rise of Thunderbolt 3.0, a simple USB-C port makes it easier than ever to hook up an eGPU and play with more speed, pixels, and power.

What exactly is an external GPU & how does it work?

An external GPU is an enclosure that contains a video card used to connect to either a PC or laptop. By using the power of the graphics card connected via the eGPU, the gaming desktop or laptop can now utilize more power, resulting in better visuals and speeds. While a dedicated power supply is guaranteed among the average GPUs, some also include extras like their own cooling system or a PCI Express slot to connect video cards.

Will any external GPU work with my laptop or desktop?

Nope. Doing your own research is very important since not every eGPU is compatible with just any computer or graphics card. Once you see a product from our list that tickles your fancy, study up on it via other online resources because every external GPU has its own specific compatibility requirements.

Basically, the two main things to look at when choosing an external GPU are the allowed card sizes and connections/ports. For example, the Akitio Node is stated to support everything from full-length, full-height, and double-width cards. The OWC Mercury Helios 3, on the other hand, only accepts cards that are 7.75″ in size.

Also look at whether the external GPU you’re interested has Thunderbolt or USB ports, or if it required a proprietary connector. Some eGPUs, like the HP Acceletaror Omen, allows you to plug in both solid-state and hard drives via a SATA port. Most importantly, there are eGUPs stated to only work with specific devices, like the Razer Core only working with Thunderbolt 3 computers.

By doing research online you might even discover that, despite the official product’s list of compatible products, a certain eGPU does in fact work with your gaming device with a few tweaks.

Even if your gaming laptop already packs a punch but still needs a little kick to match the demands of the latest games, check out our recommended best external GPUs below:
