PCI-SIG Announces PCI Express 7.0 Specification to Reach 128 GT/s
PCI-SIG today announced that the PCI Express (PCIe) 7.0 specification will double the data rate to 128 GT/s [gigatransfers per second] and is targeted for release to members in 2025.
PCI-SIG technical workgroups will be developing the PCIe 7.0 specification with the following feature goals:
- Delivering 128 GT/s raw bit rate and up to 512 GB/s bi-directionally via x16 configuration
- Utilizing PAM4 (Pulse Amplitude Modulation with 4 levels) signaling
- Focusing on the channel parameters and reach
- Continuing to deliver the low-latency and high-reliability targets
- Improving power efficiency
- Maintaining backwards compatibility with all previous generations of PCIe technology

I'm mentally OVERDRAWN! What's that SIGNPOST up ahead? Where's ROD

This is a new term for us, albiet may have been in use before.
However, even the Wiki reference link sites no confirmed sources for the metric.
What happened to Hz, you know, the cycles per second SI unit?
Is that not a lot easier than the introduction of yet another unit of measure?
What am I missing here?

It has been in use "forever", you just didn't notice it.

You're missing 20 years of computing history, because this has been in use since before the 1st PCIe 1.0 chips hit the market in early 2000s.
