Test System & Power Consumption
Gainward's GeForce GTX 650 Ti Boost card consumed 11% more power than the GTX 650 Ti and 6% more than the Radeon HD 7850 when stress tested using Crysis 3. It also used 16% less power than the GeForce GTX 660.
On the SLI side, the pair of GTX 650 Ti Boost boards consumed 323 watts, or ~40% more than a single GTX 650 Ti Boost graphics card. This was 3% less than the Radeon HD 7850 Crossfire cards and just 7% more than a single GeForce GTX 660 Ti.
The Gainward Gold Sample dual fan design works extremely well as the GTX 650 Ti Boost model ran no hotter than 42 degrees, which isnât much more than what some cards output at idle. This cooler also worked very well on the GTX 660.
