>and halves the power usage of a traditional design.

Um, really? Rumors talk of a 65W (and a 100W) Kaby Lake G CPU. The CPU is 4C/8T @ 3.1/4.1. That's 10% more than the 7700HQ which is 45W. The GPU side is rumored to be 1000MHz 24CU and 4GB HBM2 @ 700 MHz.

Now the Ryzen 5 2500U is a 15W part with 8 CUs up to 1100 MHz. The CPU surely eats some watts out of that so I do not think it's too outlandish to claim 24 CUs eat less than 30W especially with a lower frequency.

All in all, I absolutely can't see the claimed gigantic power usage savings Intel purports here. It looks like 10% perhaps 15% based on the above data. What am I missing?
