[SOLVED] Pcie 4.0 and 5.0 ; can someone explain?

[stacielovesmalphite]

It's an upcoming slot for gpus, right? One that offers higher bandwidth and can support more VRAM.

But if it's just a slot, does that mean we should expect new series of gpus that can use it?
Is the Radeon vii 16gb the only one that can use it so far?

And I assume most today's models cannot be put in it or use any of its advantages, not even the RTX?

Is pcie 4 or 5 "better"?

Each revision of the PCIE brings bandwidth improvements and is backwards compatible.

v3 is what you find on motherboards now, with v4/v5 maybe at the end of year on new premium motherboards, depends on manufacturers and chipset providers.

Any currnet GPU's will work just fine with v3 giving optimum performance, plugging in a v4 or v5 slot, will probably not yeld any advantage, this will need a new genertaion of cards designed for higher bandwitdh that is made available.
