Can someone give me a terminal command line for pcie that shows mutiple gpu connections, i.e. 16x/8x, etc.?

I want to know if I place 3 GPUs in my MB, how they are connected, i.e. how many PCIe lanes total are being used?

This is a discussion of commands, tools, and such, to get gpu info:
https://askubuntu.com/questions/5417/how-to-get-the-gpu-info

For example:

sudo lshw -numeric -C display

among -many- others. The detail you are after looks very detailed, though, and you might need the engineer’s tools!

Depending on which Distro you are running you can use the command inxi -G also. in Ubuntu you would have to install inxi first sudo apt install inxi Most other distros include it it’s a very powerful tool for figuring out systems. see here.

Thanks kc1di, I will definitely give it a try. And yes, I am running Ubuntu 20.04, so I will install first.

Kim, your suggestion gives me the most information, but not quite what I’m looking for. Thanks anyway.
