The Thunderbolt 3 eGFX box is a low cost expansion chassis designed to house an external graphics card. Connected to the computer via Thunderbolt 3, the additional GPU power instantly upgrades a regular laptop or a mini PC and makes it possible to do things that would normally require a high-end workstation or gaming computer. For video editors and colorists, the dedicated GPU reduces the time it takes to render the footage, a computer that was not powerful enough for a VR headset is now potentially VR ready and for those that like to play games, these can now run at much higher frame rates than before.
