Thunderbolt 3 Help!

[Killermove21]

Hey guys! I'm going to be buying second hand Acer predator 15 with a gtx 970m. I know it has thunderbolt 3 but I want to if I could hook it up to an egpu just in case I want to do what linus did with his razer blade. 

 

Thanks!

Not all tb3 ports are created equal nor are they all compatible with an egpu. 

 

Make sure that its

egpu enabled

4 pcie lanes

 

And keep in mind that there is a significant performance drop in gpu power. A gtx1070 will perform about on part as a regular 1060.

How do you check how many PCIe lanes the TB3 port has? 

 

And thanks for the prompt replies! Muchly appreciated?

1. Hard to check actually especially for older devices

2. x2 PCIe lanes also will work, performance loss isn't that bad

Even myself have no idea to check. All I know is through HWinfo64
