20GB Vram vs 10GB on PCIe 4.0

Basically I'm waiting for the 20gb 3080 or one of the 16gb models. What I'm wondering is will a 20gb vram card need the PCIe 4, as the 10gb version I could get away with sticking to my i7 8700k on PCIe 3.

Is Vram even related to PCIe 3/4

No makes zeros difference look at 3090

Idk why I didn't think of checking this

If I recall correctly bottlenecking PCIe 3 would require a single card equivalent to ~2x 2080Ti which even the 3090 isn't.

However that isn't taking other PCIe devices into account you might have that could take up bandwidth.

Alright sweet
