Well you get 16x PCIe 5.0 lanes but that doesn't mean it would be limited to the GPUs as it's up to the motherboard manufacturer on how to use them. Kind of like how Rocket Lake works:

"The second big difference is that the Z590 platform will enable the processor to use PCIe 4.0. Intel will include native CPU PCIe 4.0 support for the first time, 20 lanes of it, which will enable a full x16 link for add-in cards as well as another PCIe 4.0 x4 for storage. Vendors will be able to split that x16 as required, similar to previous mainstream motherboards, into an x8/x8 or x8/x4/x4 bifurcated solution, with appropriate muxing."

But only 4 of those 20 PCIe 4.0 lanes are on the CPU, the rest are on the PCH, which is not ideal for the GPU to run efficiently. So the only realistic option for the GPU is to use the PCIe 5.0 lanes. They could use only 8 lanes for it... but I doubt any mainboard producer would want to get attacked for gimping the GPU, so I don't expect any of them to do that.

They already do it with high end mobos but it's only active if the user chooses to do so. Like if the user has dual GPU setup or single GPU and a ton of SSDs or something. As 8x PCI-E 5.0 has the same bandwidth as 16x PCI-E 4.0, I could certainly see use cases if it takes a while for GPUs to move on to PCI-E 5.0 while storage is already there.
