RTX 3070 question

[Ryuzakimorgoth]

I am not yet 100% used to making upgrades on my PC,I read that the 3070 will feature PCIe 4,so my question is,will it still workd with a PCIe3? I only have an ASRock 450m/AC sadly and I don't have that on it

Yes, PCIe is backwards compatible.

Yes, PCIe is backwards/forwards compatible.

yeah it will work even on pcie2.0

just it will be bottlenecked

how much ? wait for benchmarks

 

[Drama Lama]

Yes the card will even work with PCIe gen 3 just as AMDs cards

[Helpful Tech Witch]

will probably fork on pcie 1.0. The lower the bandwidth, the higher the bottleneck though.

Okay so if I have a PCIe3,i might have a slight bottleneck? that's all?

No. Almost all mainstream GPUs will work fine with PCIe 2.0, so 3.0 will result in basically no bottleneck.

Wait for benchmarks and then we will know.

That isn't quite correct. There are a few games where the 5700XT gets a 5% increase in average fps when using PCIe 4 over PCIe 3, and the 5700XT isn't a particularly strong card but it is the strongest card out right now that currently supports PCIe 4.0. Who knows that kind of bottleneck you could see running a more powerful PCIe 4 card like the RTX 3080 or 3090 using only PCIe 3. Espeically, if games become more PCIe 4 optimzied. Here's my source

Hmm So I guess that will be the determining factor on if I get a 2080TI or a 3070.
