While we are on the horizon of seeing PCI Express 6.0 devices, there are already early Linux kernel patches beginning to surface for PCI Express 7.0.

The PCI-SIG officially released the PCIe 7.0 specification i nmid-2025. PCI Express 7.0 doubles the raw data rate to 128 GT/s to allow for 512GB/s bi-directional communication in a PCIe 7.0 x16 configuration. PCIe 7.0 retains backwards compatibility with prior PCIe revisions, offers power efficiency improvements, and other enhancements.

Impressive for sure, but why, pcie6.0 devices are barely(if any) on the market, almost none for consumers. Do we really need pcie 7.0?

Do we really need more than 640k of RAM?

I believe the PCI-e revisions are usually used in datacenters before home computers, and of course Linux is really big for datacenters...

but also this could be preparations for 2028 or even 2029 hardware, datacenters especially need this stuff to be really stable so it's gotta be done in advance

It will still be quite some time before seeing any PCIe 7.0 hardware (likely late 2027 to 2028) but already early preparations are underway toward Linux support for the PCI Express 7.0 revision.
