gpumacbook propowertemperature
I noticed that running with the discrete GPU uses more power and generates more heat. I just need the discrete GPU to drive an external monitor, I'm not concerned about performance.
By controling the power state I expect to control the voltage and frequency of the GPU. This could be achieved by either changing the power state of the GPU or the voltage and frequency directly.
I just want to make sure that the MBP runs as cool as possible.
I found the link to it on EveryMac along with some other info about graphics switching.
Instead of resenting the SMC (a painful procedure) try this free software.
gfxCardStatus It is an unobtrusive menu bar app for OS X that allows MacBook Pro users to see which apps are affecting their battery life by using the more power-hungry graphics and
Manually switch to Integrated Only or Discrete Only mode to force one GPU on or the other.
Since I am not sure of your model year, it works on:
OS X Lion (10.7) or newer
2008-2012, 15-17" dual-GPU MacBook Pro

I use gfxCardStatus to see and control if my discrete GPU is in use. Is that what you want?
To see how much power is consumed you can use iStat Menu for example...
