3000 NVidia + PCIE 3.0 or 4.0?

[Rauten]

Good day ladies and gentlemen,

 

I have some plans to upgrade my current build while reusing the motherboard, but I do have a spot of concern -  what if the Ampere cards need PCIE 4.0 to perform correctly?

 

Now, I realize this is unlikely as even a 2080Ti barely overwhelms a PCIE3.0 8x slot (why yes, I just googled that) but the possibility still bothers me.

I've been looking around the internet but can't find anything definitive about it, so I turn to you for knowledge - Has there been any indication or data supporting the idea that Ampere might need PCIE 4.0? Or on the contrary, PCIE 3.0 can still serve me well for many years?

 

Context: Some juicy deals going on for the R9 3900x in my country right now and really tempted to pull the trigger, and I want to keep using my X370 motherboard. No point in buying this CPU right now if the GPU is going to force me to change platform later this year.

I doubt it'll make a noticeable difference whether you're on PCIe 4.0 or PCIe 3.0 16x.

It won't ,

Ok well its not guaranteed that it won't but considering the generational improvements we get 

It's not huge and I don't expect this to be a massive ground breaking thing 

Even if it was, it will likely only saturate the x16 gen 3 bandwidth .

I honestly wouldnt get a 3900x and keep it on x370 if im honest. 3800x-3950x you should get a b550/x570 motherboard to get the best out of it. 

 

Graphics cards dont even do enough do warrant pcie3 x16, let alone pcie4 x16. Maybe in 6 years, 2 GPU Familys later it may matter, but by that time we will be using PCIE 5 and Things will be a fair bit different.

I vaguely recall Nvidia once saying that amphere would be 3.0.  They might have changed their minds of course.

That's not happening anytime soon...modern graphics cards don't even use half the bandwidht provided by PCIe 3.0

Pcie 4.0 is here more for fast storage improvements...graphics card don't need it.

Need, no. Pci-e is backwards compatible so it is not needed.

 

Benefit from? Possibly, but it won't be anything major, if at all.
