PCIe 5 GPUs in PCIe 4 Slots

Delta3D said:
Given that the 50XX series are rumoured to land with PCIe 5 support, do we expect there will actually be much benefit to swapping to a PCIe 5 board?

As far as I'm aware, current GPU's aren't really maxing PCIe 4 slots? With that, my presumption is that the 50XX series will likely (although obviously unconfirmable) suffer no issues in a PCIe 4.0 slot.

The 5090 will probably be 1-2% faster with PCIe-v5 compared to PCIe-v4. 5090 will also be a few % faster on a new CPU (13900k, 14900k, 7800x3d, 9800x3d). When adding up all these small %, it can equate to a big number.

Bear in mind there's going to be an army of people buying 5090's and using them with Ryzen 5000 series, 10th gen Intel and 60hz monitors - which IMO is completely bonkers, but each to his own :D

I don't know how true it is but there are videos on YouTube showing the difference between a 5800x3d and a 9800x3d at 4k with a 4090 isn't really that big...
