USB-C external GPU

An external graphics card aka eGPU allows you to house a desktop graphics card and connect it to your laptop, allowing it to run apps or connect it to an external monitor with the desktop graphics card.

Currently, it’s possible to embrace the full power of desktop-grade GOUs on an eGPU thanks to the latest technologies such as Thunderbolt 3 that provides bandwidth up to 40Gbp.

All major companies have released their eGPU enclosures to try and create the best external graphics card on the market.

Before the adoption of Thunderbolt connectivity in lots of high-end laptops, eGPUs never got the chance to take off due to the limitations of bandwidth when using USB 2.0 to connect the laptop to the eGPU.

But now, Thunderbolt 3 offers bandwidth that provides four times the speed of USB-C. Here are five of the best eGPUs that you can find on the market today that comes with USB-C ports.
