Overall Energy Consumption and Energy Saving
These power consumption levels are calculated using all of the results and combinations in the test; the individual values have been added together. These values only show the tendency of the relevant component: the actual power consumption of the graphics card varies according to CPU, and in turn, the power consumption of the CPU varies depending on the graphics card.
If you wish to save power, you can switch from the Geforce 7 to the Geforce 9600 GT—this provides much more performance and only puts minimal extra load on the power supply. The Geforce 8800 GTS 512 OC is a little more efficient in 2D mode than the new Geforce 9800 GTX, but they are almost identical in 3D mode.
|Power consumption GPUfor all combinations||2D watts(Vista Desktop)||3D watts(BlackSite)|
|8800 GTS OC (512 MB)||788||1554|
|9800 GTX (512 MB)||813||1534|
|8800 GT OC (512 MB)||723||1377|
|9600 GT OC (1024 MB)||637||1083|
|6800 GT (256 MB)||707||1045|
|7950 GT (512 MB)||600||995|
The overclocking of the Q6600 can be seen clearly from the power consumption figures. The consumption of the E2160 barely increases, although the clocking has been raised by 33%.
