Will an eGPU thunderbolt3 function on an USB 3.1 type c?

Thx!

Yes.

Yes.

At the full thunderbolt 3 speed?

Depends what the Port really supports. Thunderbolt 3 is about 4 times faster then USB 3.1. But many USB-C Ports support TB3 and USB 3.1. In any case will any USB-C 3.1 be able to use TB3 at lower speed (when not supporting both), while TB3 wont automatically be able to use 3.1...

a bit complicated but short version. really depends on the port itself but in the end Thunderbolt uses 4 PCIe lanes while GPU's normally use 16 PCIe lanes...so in anycase expect far less performance then with an real GPU.

But it will not function at the 40 Gb/s from thunderbolt 3? I mean how do i know if my USB c 3.1 supports thunderbolt 3 at thunderbolt 3 speed?

USB 3.1 Type c is kind of a strange connector. It will do thunderbolt 3. Thunderbolt 3 in only found in USB 3.1 type c. USB 3.1 Type c also does displayport with a adapter.

So it will work at a lower speed? Yes/No

No. USB 3.1 c = Thunderbolt 3.

You will get Thunderbolt 3 speeds.

But is USB type c the same as USB 3.1?

Yes and no. Type c uses a different connector and has DP and TB build in.

They are and they aren't. USB-C is a slightly better version of USB 3.1. It can do everything 3.1 can do and a little more.

Yes and no. Type c uses a different connector and has DP and TB build in.

But if USB c 3.1 is 10 Gb/s how is it then possible that thunderbolt 3 functions at 40gb/s? Or Does USB c 3.1 support 40 Gb/s?

Bit old but explains things well.

Thunderbolt 3 can only be found in USB 3.1 c.

It's many connectors build into one.

I was just as mind ♥♥♥♥♥♥ when I first heard about Thunderbolt 3 as you are.

Conclusion: thunderbolt 3 functions at 40gb/s in an USB 3.1 type c port. Yes/No
