I've got an i7-6700 running on an ASRock z170 board with an nvidia graphics card. When I run the intel power gadget 3 software, it says the CPU is using 12 watts and the IA is using 1.5 watts. I can only conclude that the integrated GPU is using around 10 watts even though I'm using the nvidia card exclusively. The intel GPU doesn't even show in the device manager.
