Does better graphics card use more battery and generate more heat?

    Hi all, I'm going to get a new MBP 15" and considering upgrading graphics card to 460. But I'm hesitant because some people say 460 could use more battery and generate more heat than 450/455. Is that true? Anyone has any information on this or test results of 15" models with different graphics cards?

    I have the 2015 MBP with the Radeon dGPU. I never have a use for it but the few times I did notice the MBP was using that card, the fans would spin up to the maximum RPM. Obviously, it's generating more hear using that card.

    I only have one app that would use the dGPU and that is the included photos app. Not sure if this will help you or not.

    The 15" have both integtrated and discrete graphics and automatically switches to what it needed to be the most effecient. So I wouldn't fret over heat or battery if you have a need for the higher card. There are apps that you can use to force into discrete or integrated if you don't like what the computer is picking.
