New lineup of NVIDIA Graphics Card based on PCI-E 4.0 ?

[SubankS]

Will the new lineup of graphics cards from NVIDIA (supposedly named RTX 2080,RTX 2070 and so on)be based on PCI-E 4.0 slot ? If it is , then will it work with a PCI-E 3.0 slot ? 
I am looking forward to a build and hoping to buy the RTX 2080 . My motherboard in choice is Asus ROG Z370-F . Will the RTX 2080 work with it? This dilemma is preventing me from buying the components before-hand . Please answer . Any kind of help is appreciated . Thank you in advance .

Any newer PCIe gen also works on the older gen PCIe. It will just run om the older PCIe speed. 

 

You can run the newer cards on PCIe 3.0 without performance loss.

PCIe 4.0 will be backwards compatible, so 4.0 cards will work in 3.0 slots (at 3.0 speeds) and the other way around.

i think we need a modern AGP

a port dedicated to graphics cards

PCIe 4.0 seems to be unnecessary for most applications since even the Titan Xp isn't bottlenecked by it. The Titan V is barely affected. Everything here is from some askgn on the YouTube channel Gamers Nexus. I don't think next-gen will be powerful enough to bottleneck.

I think its got more to do with reducing the number of pcie lanes than anything.  Ie, gpu, usb3, tb3, 10g lan ALL in a single 16 lane spread.
