What no USB 4.0?

With PCIE 5.0 you can run a 10GBe off of a single pcie lane. With gen 3 it requires 4 lanes or 2 lanes with gen 4. Basically 10GBe can be made standard with PCIE 5.0. It also opens up more lanes for adding more USB ports or faster usb ports. Such as usb 3.1 gen 2. Or it frees up more lanes for more NVME devices.

And thinking about it it is quite sad that PCIE needed over a decade to achieve what Ethernet got over 4 physical contacts and a much longer distance. Not the same, I know, but just the difference in distance should make up for that.

AMD and Gigabyte just showcased a new nvme m.2 drive with PCIE 4 already during the AMD event showing off Ryzen 3k, so these drives will definitely be coming within the next few months. Even sooner than I had previously thought

When PCIE 5 drops Im sure adoption for SSDs will be similarly fast
