Frequently Asked Questions

What do I need to use an eGPU?

A laptop or mini PC with a compatible Thunderbolt, USB4, or OCuLink port, plus a desktop graphics card to install in the enclosure.

Thunderbolt/USB4 is widely supported and plug-and-play; OCuLink offers higher bandwidth and less bottlenecking but requires a host with an OCuLink port.

Will an eGPU bottleneck my graphics card?

There is some bandwidth loss over external connections, more on Thunderbolt than OCuLink, but the performance gain over integrated graphics is still large.

Can an eGPU charge my laptop?

Many full-size enclosures like the Core X supply power to charge the laptop over the same cable. Check the enclosure’s power delivery spec.
