@whitekiba @Jain @golem And yes I'd love to see a vendor-independent x32 if not x64 & x128 connector...

Even if that means some chonky "#OCuLink meets MTP" connector with several fibers to save space...

At least a x32 would make sense even on "consumer grade" systems if we'd embrace #backplanes instead of ATX Motherboards, reducing upgrade costs...

@whitekiba @Jain @golem I've yet to see it's connector cuz nowhere was I able to find it...

With PCIe 4.0 that was sadly omnitted from the spec.

And yes there are valid reasons for it:
Like industrial #SBC-based systems which may even utilize passive #PCIe #backplanes that do #Bifurcation per #Chipset, omnitting the need for expensive PCIe #switches.
Kinda like the passive PCIe x16 => 4x NVMe (PCIe x4) cards.

So one would be able to add more stuff onto the backplane...
