GTX 1660 Ti in a PCIe x4 slot

14 minutes ago, davidst95 said:

Hi, just a quick question.  Will running a GTX 1660 Ti in a PCIe 3.0 x16 slot but running at x4 speed impact the video cards performance?  Thanks!

 

David

Yes,

 

GN did a piece comparing x16 to x8 and there was a large difference. I can only imagine that x4 will be even worse. https://www.gamersnexus.net/guides/2488-pci-e-3-x8-vs-x16-performance-impact-on-gpus

 

Edit:

I miss understood this data. This shows a very small difference.

I did, good catch though. I miss interpreted the numbers when looking through them.

Did you read that? It made no difference. That was also with a GTX 1080, which is much more powerful.

Testing with the Titan V also showed little change between 16x and 8x. With 4x having some impact.
