Temperature and Power Consumption
To gauge the temperature of each graphics card we take a real-world approach of playing through Crysis 2 at maximum settings instead of running a synthetic benchmark. This allows us to reproduce the type of temperatures a typical game would see. To ensure we reach equilibrium when testing we run the game for 15 minutes and collect the minimum and maximum temperatures from GPU-Z.
The thermal solution used on the GeForce GTX 650 Ti is actually rather small, but despite this the GPU temperature never exceeded 65°C. On top of this the fan was incredibly quiet and there was not a time during our testing when the fans noise level was noticeable beyond a whisper.
We test the power consumption of graphics cards the same way we test the temperature. We run Crysis 2 for 15 minutes with the settings maxed out and we use a Kill A Watt P4400 power meter to record both the idle and peak power states. The idle power rating though is taken after the system has been idle for 10 minutes, but not in Sleep mode.
When it comes down to thermal efficiency the GTX 650 Ti is a clear winner. At times of peak power consumption our whole system was only drawing in 191 watts of power, not bad for a card with this level of performance.
