But this is not the point of my thread, reading this article made me wonder about something i already noticed on my graphic card a long time ago but couldn't careless.
2D Clock? What is it?
Is it a clock that will be used when the card is using 2d environment like windows in order to save power? If so, i could lower it to the minimun possible and it wouldn't affect my gaming performance because original 3d clocks would be reestablished when playing anything concerning 3d environment?
More aboutwhat clocks
Reading the article it would seem that you are correct. This would be a great move IMHO specially considering the power consumption of those monsters but when you take into consideration the source this should be taken with a pinch of salt.
The OP is right; 2D clocks are the lower clockspeeds a GPU runs at when doing things such as word processing, surfing the web, etc. to save power.
