You're talking about Alder Lake there? Because that's a no.

Alder Lake has only 16 PCIe 5.0 lanes, all for the GPU slot(s). SSDs only get 4.0 or even 3.0 (PCH has both 4.0 and 3.0) depending on how the connector is wired.

In other words, if you want to connect your SSD with PCIe 5.0, you'll have to wait until at least 2022.

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.
