T420s (20HF) - External GPU/eGPU over Thunderbolt 3?

2020-07-08, 8:48 AM

Hi,

 

Dose my T420s (20HF) support eGPU (external graphic cards)?

 

I called the Lenovo support but they said No but he was using Google to find that information, not their internal documentation.

When I user Google I found (mostly) that you can but it has only 2 PCI-lanes instead of 4 so I would like some confirmation from here as well :)

 

Thank you!
