Two separate evidence layers

PCIe connector form vs PCI Express implementation

Distinguish PCIe card-edge and cabled physical forms from lane count, generation and exact system support.

Question this page answers

Does a PCIe-labeled physical interface tell me the implemented lane count, generation or device support?

No. Use the physical connector records to identify the form, then verify the implementation on the exact device, cable, adapter or system documentation.

Discovery is not a compatibility verdict.

These discovery surfaces route and reorganize facts already represented in the atlas. They do not add electrical ratings, universal pinouts, measured tolerances, exact-device support, wiring approval or an end-to-end compatibility result.
