Looks like my 5500M GPU draws 10W fewer when I change my external 4K monitor from Scaled (to accommodate for every OS UI element being minuscule) to the display's native resolution. It makes the OS barely usable from a UI standpoint, but the fans are now a lot quieter. I'm on a Dell monitor.

Is this by design?

I just tested it on my 2017 rMBP (Radeon 555), and I saw an immediate drop from ~15W to 11W. The total power usage is around 30W, so it's an immediate ~15% drop in power usage.
