This is very interesting and first time I’ve heard / thought about this. Wonder how much power efficiency comes from exactly these things?

PCI is quite power hungry when it works on full trottle.

The seemed power efficiency when PCIE was going 1.0 2.0 3.0 ... was due to dynamic power control, and link sleep.

On top of it, they simply don't haul memory nonstop over PCIE anymore, since data going to/from GPU is simply not moving anywhere.
