Best External GPUs for Laptops

Laptops are portable and are great for when you want to give a presentation, crunch some numbers, binge-watch your favorite shows. But when it comes to high-end gaming that tax the graphics card, most laptops just can not keep up. External Graphic Cards (eGPUs) have brought the world of high-end gaming to laptops.

With an external GPU, you do not need to upgrade your entire gaming setup to get the best out of your graphics. On the chance that you have a laptop with a Thunderbolt 3 Port, you can very well attach an external GPU (eGPU), which will provide all the benefits of an Nvidia or AMD graphics card. There are some that can be connected to MacBooks also.

Gaming laptops have been introduced into the market. Yet they have been known to suffer from the increased weight, poor cooling, and sometimes inferior graphics. Until the recent technological advancement, most laptop gamers had to pick between the best gaming experience and mobility.

An external GPU means you can have the best of both worlds. The external graphics card connects to the laptop and provides it with the performance and power of any modern GPU on the market.

GPUs are majorly used for three purposes; media, gaming, and recently cryptocurrency mining. Desktop users will be more familiar with the graphics card as it has a great effect on graphical fidelity while gaming.

An external GPU is the industry designation for a special chassis with proprietary software and cooling properties in which an internal GPU is inserted into. This chassis is then plugged into a Thunderbolt 3 port where it will run the GPU at full-power. The external GPU provides the best possible environment to run an Internal Graphics card.

Basically an eGPU is an external plug and play case for your GPU. Getting one of these external GPUs can be a bit tricky, which is why we created this guide. It will walk you through the basics of each graphics card so you can make an informed decision when deciding which is best for you.

What You Should Consider When Getting an External GPU for Your Laptop


Some models have restrictions on their compatibility. For example, Razer eGPUs operate best with Razer laptops and struggle to match the same performance on other laptops. When selecting an eGPU, look for one that supports your laptop.


Graphic cards produce a lot of heat which makes external chassis to be fitted with fans or other cooling technology to cool the cards down. Sufficient colling will enable your card to have a long and healthy product life.


Some cards are long in length with the Nvidia GTX 10-Series running from 11-12 inches in length. It is absolutely necessary to pick an external GPU that can house your card. Make sure to double-check this before purchasing or you might find yourself needing another chassis.


All External GPUs have a power supply that helps in the running of the GPU as well as charge your laptop. Make sure your card is compatible with the electrical properties of your external GPU and laptop. Most cards will run well with the eGPUs on the list below.


Most external chasses come with an extra port to plug-in peripherals, monitors, ethernet, etc. These could come in as very useful as you can make a docking station from an eGPU.
