TDP versus Real Energy Usage

TDP, or thermal design power, basically says how much heat, in watts, a CPU/GPU gives off at maximum. For example, my graphics card has a TDP of 75W. About how many watts in general actually go to render graphics? It obviously depends from card to card (or processor to processor), but I'm looking for a ballpark estimate. I'm guessing the number is very low.

    It's an old article but it may help.

  2. My understanding is often the quoted number is the typical value for power consumption. If you use a program to truly max the card (furmark) you can get higher.
