Energy Efficiency

Energy Efficiency calculations are based on measurements using Cyberpunk 2077. We record power draw and FPS rate to calculate the energy efficiency of the graphics card as it operates.



Voltage Frequency Curve

The card will dynamically adjust clocks and voltage based on render load, temperature, and other factors.

For the graph below, we recorded all GPU clock and GPU voltage combinations of our 1440p resolution benchmarking suite. The plotted points are transparent, which allows them to add up to indicate more often used values. A light color means the clock and voltage combination is rarely used, and a dark color means it's active more often. The minimum and maximum values are 99th and 1st percentile, so outliers are excluded.
