How can eGPUs help you?

An eGPU is a simple empty chassis that houses a PCI expansion slot for a graphics card and a power supply to run the graphics card. Pretty simple.

External GPUs are ideal for laptops as they alleviate the additional burden, enabling the eGPU to handle intensive tasks. Most eGPUs are compatible with Thunderbolt 3-enabled Windows PCs and are conveniently portable in a laptop bag.

Remember that the prices vary on the graphics cards you can buy along with the eGPU case (I recommend you to buy the case and the graphics card individually). According to Apple, to use an eGPU, you need a Mac that is equipped with Thunderbolt 3 and running High Sierra (macOS 10.13.4) or later (macOS Catalina or Big Sur). High Sierra is a stable macOS version that solves the compatibility issues with eGPUs.

Potential Mac gamers should also verify that the eGPU’s power supply is sufficient for their desired graphics card. Prior to purchase, carefully review the device’s description to ensure compatibility with the GPU.

If you enjoy open-world RPG games like The Witcher 3, choose a GTX 1070 or 20XX series for optimal framerates. For games with moderate graphics demands like cartoony shooters Fortnite or Overwatch, a GTX 1060 or 20XX series will suffice, easily achieving over 60 FPS on max settings. It is still an excellent graphics card by current standards.

Consider configuring your external graphics card processor with a high refresh rate monitor for optimal performance. To meet the demanding requirements of gamers, it is recommended to utilize an external monitor instead of the pre-installed options on the Macbook.
