"They say", but they're right. Ryzen chips do have worse idle power usage, but you're talking about 10w or so, at most.
And uh, if you were looking at an X-series CPU, I can't see how that 10w is a dealbreaker, because you were already looking at a shockingly inefficient chip.
And more fun, lots of laptops have really goofy routing. I've got one where the DP alt mode on the USB-C ports are on the dGPU, but the HDMI ports are on the iGPU. And the internal panel is on the iGPU unless you switch it to be on the dGPU because yay mux.
Why? I don't know. Too much meth while laying the board out or something I guess.
