Importance of PCI-E 4.0 vs 3.0

It does not matter much if at all. You won't notice a difference.

Hi!

 

So I picked up a decently good deal on a 3080ti and I was just wondering what if any performance discrepancy I could expect to see running at PCI-E 3.0 x16 instead of 4.0. My understanding was that it should be negligible but I figured it couldn't hurt to ask since I've not kept up with things for a couple years.

Thanks! That's what I figured but wanted to confirm it.

Depends on what you're doing. If you're gaming, 2-3% depending on the game. Odds are you won't notice. If you're doing more production focused stuff, rendering and stuff like that where you can actually max out the bandwidth of the card, it'll be pretty noticeable. 

 

This changes if you're using a different card. For a 3060 it makes basically no difference in everything but the most bandwidth intensive workloads. For a 6500XT it's a pretty huge difference, even in gaming.
