Graphics Cards Guide
Temperature & Power Consumption Results
Like the GTX Titan, the GeForce GTX 780 is also using NVIDIA's new GPU Boost 2.0 technology. According to the our performance logs during our overclocking exercise, its operating temperature actually hit a maximum of 83 degrees Celsius, but it quickly tapered off after the end of the benchmark. As we have noted in our Titan review, with the temperature now acting as the main gatekeeper when factoring how much it can boost the clock speeds, cards with GPU Boost 2.0 enabled would tend to operate at the 80 degrees Celsius threshold to perform at optimal levels.
Having said that, the GeForce GTX 780 registered a cool 77 degrees Celsius during our temperature tests, making it the second coolest of the high-end graphics cards lot.
Power Consumption Results
The GTX 780's power consumption figures are naturally slightly lower than the GTX Titan due to the former's lower number of active CUDA cores. Also note that it's almost on par with the AMD Radeon HD 7970 GHz Edition card, which means the GeForce GTX 780 is providing a lot better performance per watt.
