Using Arch Linux and kernel 4.8.3, I am observing much higher power usage in powertop when using Nouveau with vgaswitcharoo (~13W) opposed to NVIDIA/Bumblebee with BBSwitch (~7.5 W).
I initially started noticing this because the battery drained much faster and the fans started to spin while they otherwise stayed idle.
Attached is my dmesg log.
