Real world difference between x8 & x16 pci-e

Robzere31 · 14 Feb 2014 at 21:24

Is there a real difference between running the graphic card in the x16 slot & x8 slot?
I ask because I've managed to damage my x16 slot on my motherboard so have placed the gpu into the x8 slot.
Run a quick benchmark & there doesn't seem to be a difference TBH.

Up to 5% apparently. I certainly wouldn't worry

Thats what I thought, just run the benchmark on Grid 2 1080P full ultra settings & got average FPS of 100

What card is that you're using?

Board is only 2 months old (MSI Z87-G45) but it was my own fault that the PCI-e 3 slot was damaged.
I'll probably upgrade the MB if & when I ever go SLI.

Card is an MSI 290 @ stock clocks, just testing it out as it's an RMA replacement that arrived today.

Maximum PC did some benchmarking, which included the difference between PCIe 2.0/3.0 and x8/16, not even a week old yet so about as up to date as you can get:
