While some come with an included GPU, others may require you to splurge on a new graphics card, which plays a considerable role while evaluating which eGPU you should buy. The most popular options on the market support Thunderbolt 3, making them compatible with almost all recent laptops. Despite being a niche product, eGPUs allow gamers to power up their ultrabook and non-gaming laptops whenever they need to.

This is where external graphics cards (eGPU) come in.

Ultrabooks’ small form factor makes them the perfect candidate for such mobile usage, but most lack a GPU, which prevents them from running games smoothly. You can always take your gaming laptop to school or work, but you’ll be working out your arm muscles simultaneously. Though gaming laptops emerged to fix this problem by featuring desktop-grade graphics cards and top-of-the-line cooling systems, their size and weight decreased their usability for mobile users. You’ll always need a monitor, a keyboard, and a mouse to use your system. While they’re powerful machines, moving them around can be too much of a hassle. Gaming on a high-end desktop PC will give you the best experience in terms of performance and high quality.
