Intel Comet Lake-S CPUs and Z490 boards support PCI-E 4.0 (but it's not active)
A new report on the web indicates that the upcoming Comet Lake-S processors (tenth generation of Intel Core for desktop) actually do support PCI Express 4.0, some Z490 motherboards are designed for it as well. However an issue prevents PCIe 4.0 to become usable, so the platform will support PCI-E 3.0 instead.
The reason behind this is presence of Jitter in the Z490 chipset signal, that causes instability in the data signal and that menas that specifications required for the PCI-Express 4.0 certification are simply not met. PCI-E 4.0 is working at very high frequencies, and that requires that the signal be completely clean.
Several manufacturers added external clock generators to eliminate this Jitter, however not everyone did, so Intel made the decision to not support PCI-E 4.0 on this new platform.

History will repeat and Intel will bring us a core 2 duo era once again claiming the performance crown for another decade. Its inevitable. Until then its Ryzen time.

So she said she lied and tricked Intel? That doesn't quite sound like her but alright, will have to take your word for it due to a lack of information on my end after asking.

All bs to me, I need a built-in Thunderbolt 3 port on the motherboard, not the current add-in card thing. Come on Intel and AMD!!!
Also, I love this thread https://forums.guru3d.com/threads/nvidia-jen-hsun-huang-is-uncle-of-amd’s-ceo-lisa-su.422662/

I'm guessing you're not an AMD fan or stock holder. She has said this when she accepted the CEO job at AMD. As a shareholder I have followed AMD's statements pretty well.
