Can all PCIe 4.0 GPU be used on all PCIe 3.0 motherboard?

Can all PCIe 4.0 GPU be used on all PCIe 3.0 motherboard?

(I know it will run at a reduced bandwidth)

Yes.

Reduced bandwidth, but not enough to cause a bottleneck due to the PCI-E 3.0 X16 slot.

I'm not asking for myself, I'm running a RTX 2060 and have no need to upgrade. One of my friend wants to upgrade his GPU on his 7 year old (judging by the CPU) machine.

At that point, he should probably upgrade his own system.

Cool tech tip inside:

Well...okay...would be nice if we were told that.

It's okay.

 

What GPU is your friend trying to upgrade to?

Regardless, PCI-E 3.0 X16 is equivalent bandwidth to PCI-E 4.0 X8, so not a problem (unless...he gets like a RTX 3080 / 3090 or something)

It will run, but might not get as much performance uplift as expected on a 6-year old machine depending on what that is exactly.
