Anyone considered running a new PCIe 4.0 GPU on a x4 4.0 slot?
I'm on X570 so limited to 20 lanes. (Threadripper is great for lanes, but it's big, expensive, and slow on singlecore. so 5000 series + x570 it is)
Anyhow, the primary x16 4.0 slot seems like a bit of a waste for a 4.0 GPU equipped GPU.
This would be like similar data rate to if a x32 PCIE 3.0 slot existed, which we can safely say is overkill for gaming scenarios. YMMV (eg maybe machine learning its useful?)
Hence wanting to run the GPU on the remaining x4 (x16 physical) 4.0 slot (Slot 3 in my case).
In theory, when paired with a 4.0 GPU (Nvidia RTX 3000 series / AMD RX 6000 series) it should equate to a 8x PCIE 3.0 data rate. Which when tested only suffers a small (few percent) fps decrease over x16 3.0. At least that's what I think.
Maybe this gives someone else some ideas to about new build options. I could also be wrong, so just happy with any feedback. Even if it's to say "only an idiot would do that" ?
