Determining the Comparable Values on the Test System
We started by measuring the maximum and minimum values for each graphics card in our test system, in order to improve our evaluation of the individual applications at the later stages.
Maximum Power Consumption
Minimum Power Consumption
Power Consumption for the Relevant Applications
We save this bunch of charts for the individual applications because, in most cases, the cards are on par and most differences are only marginal. The power consumption in games is significantly lower than the determined maximum energy consumption. But we want to state that none of the tested cards in the middle class were able to best any of their comparable competitors.
It was, however, interesting to see that both manufacturers put the cards at maximum clock frequencies when older 2D applications using GDI/GDI+ commands are used. This did not result in any positive effects on performance (we measured using our Tom2D tool), but indeed in negative effects on power consumption.
