Thunderbolt 3 with ONLY 20Gbps??

[traxxas4277]

I am getting an eGPU for my Asus ROG G752VL and the specifications on the a couple sites say "Thunderbolt 3 USB Type C 40Gbps" and then some say "Thunderbolt 3 USB Type C 20Gbps."

I thought Thunderbolt 3 is supposed to have 40Gbps!? Can someone please read up on this topic and give me an answer or not if this is true, because I am going to pick up the eGPU tomorrow and I want to know if it is worth buying or not.

Because 20Gbps is probably way to slow to run and sort of higher end graphics cards.

Thanks.

I downloaded AIDA64 and did the same steps as the photo see if it is x4 or x2, but all it says in "Devices--PCI Devices--Bus Type" is "PCI." I don't know what this means, is there any other program to find the information about my Thunderbolt 3 specifications?
