Can't they use proper units? I refuse to even read this.

These are the standard and correct units.

No, GT/s is not, regardless of the downvotes, please point me to the standard that defines them if I'm wrong. Let's keep using the boring GB/s since we are still talking about data.

The PCIe standard uses GT/s: https://pcisig.com/specifications/pcie-70-specification-vers...

This is not the same as Gb/s. There's a few percentage points difference due to error correction.
