What version of PCIe does the x360 13-ay1076ng (13-ay1***) support.

I have a PCIe Gen 3 that came with it but I want to upgrade to a faster  Gen 4 and larger capacity SSD.

Your notebook's model series comes with the AMD Ryzen 5xxx series processors.

The PCIe revision for all models is 3.0.

While a Gen 4.0 NVMe SSD will work, it will not run at its maximum advertised read/write speeds from the Gen 3.0 SSD slot.

I looked up the exact Ryzen processor on this and it seems it is compatible with up to x8 lanes. AMD Ryzen 7 5800U Specs | TechPowerUp CPU Database

So I may try get a gen4 with 8x lanes for future compatibility with newer laptops.

I would definitely buy a Gen 4.0 SSD because most of them don't cost much more than the Gen 3's and in some cases, they cost even less and certainly if you plan to move it to a newer PC in the future that has full support for a Gen 4.0 SSD.

The official AMD specs under the Connectivity section indicate the processor/motherboard is PCIe 3.0.
