Nvidia GeForce GTX 460 1GB Fermi - Power Consumption and Noise
We record power consumption using a mains power meter, as such the results shown reflect the total system power. The idle figure shows the power consumption when the system is doing nothing except showing the Windows desktop while the under load figure is taken while performing a run through of our Crysis timedemo with settings of 1,920 x 1,200 with 2xAA.
Noise readings are taken with the entire system (except the power supply, and disk drives) enclosed in a sound reducing box. A decibel meter is then held 30 centimetres away from the card while all other components are passively cooled. Again, we measure when at the desktop and when running Crysis.
