Mobile GPUs PCI-e x16 interface

Hello dear community and Linus!

 

I was recently watching Linus new video about the new Gigabyte Aorus laptop with 10th gen I7 and RTX 2070 Super when Linus stated something like "This is the first time in history that the mobile GPUs will have a full x16 lane instead of x8 to play with" showing on video the following screenshot from GPU-Z

 

The Video with the time stamp at the moment of showing the GPU-Z screenshot.

 

Then, I was wondering if I remembered wrong what I've seen in my GPU-Z regarding my own GTX 1060 (Not Max-Q) in my Lenovo Legion Y720. I have this laptop from 2016. So, I was checking if my GPU really has x8 interface instead of x16 and surprise, it didn't. It has x16 interface. Double checked in HWINFO64 to be sure, still x16. 

 

So, now comes the question: Did Linus stated something wrong in the video (It's okay, everybody makes mistakes) or do I have a special kind of laptop that I was not aware of?

 

Thanks!

It is true that most laptops run x8 to save lanes for something else, M.2 slot that gets connection directly to CPU rather than routing through the chipset or more/faster USB. On my laptop I suppose HP did this to enable TB3 support.

probably, exceptions do exists, and its not like everything that comes from LTT is factual. 

 

 

not that the extra PCIe bandwidt matters outside of very specific workloads.
