AMD Radeon HD 4770 Idle Temperature:
Since video card temperatures and the heat generated by next-generation cards have become an area of concern among enthusiasts and gamers, we want to take a closer look at how these cards generate heat under load. In order to get proper temperature readings of both the graphics cards I used GPU-Z 0.33 to monitor and log the GPU temperature. As you can see from the screen shot above, the idle state of the ATI Radeon HD 4770 had the idle temperature sitting at 46C. Let’s compare that to some other cards while playing S.T.A.L.K.E.R. Clear Sky in order to get the highest load temperature while playing at 1280×1024 with all the settings on high.
Power Consumption Results: The twin heat-pipe cooler used on the ATI Radeon HD 47700 did a fairly good job and the highest temperature recorded in the log while gaming was just 68C.
