PCIe 8.0 Announced by the PCI-Sig Will Double Throughput Again

What makes you think that?

They're small and efficient, that means they can pack large numbers of those into small spaces, resulting in a similar large power draw per volume occupied by equipment in the DC. This is especially true with Apple's "Ultrafusion" tech which they're developing as quasi-analog to Nvidia Grace (Hopper) superchips.

Because I worked on them, before retiring. Yes they’re packed in; no they still don’t draw the same levels of power.

Didn't saw they draw the same, I openly acknowledge their more efficient. Said power user per rack unit is trending up. This is true of Apple DC's as well, especially with their new larger/fused chip initiatives. It's an universal industry trends especially with AI compute, and Apple is not immune.

Let me rephrase to: No, they (collectively) don’t draw the same levels of power. I know what amperage is drawn by each rack. It’s nowhere near as much as was drawn by the older intel-based racks.

And yes, they’re packed densely.
