How Much Faster Is It?
According to NVIDIA, the new GeForce GTX 780 will be at least 70% faster than the GeForce GTX 580, and about 33% faster than the GeForce GTX 680. This is based on an aggregate of 20 games running at resolutions of 2560x1600 and 1920x1080 at High settings.
When compared to the AMD Radeon HD 7970 GHz Edition, the new GeForce GTX 780 was about 30% faster overall. With a maximum board TDP of 250 watts, the GeForce GTX 780 also uses less power and runs cooler than the Radeon HD 7970 GHz Edition.
So at this moment, the GeForce GTX 780 has no real competitor, except for its bigger brother, the NVIDIA GeForce TITAN.
Optimized SLI Performance
NVIDIA naturally thinks that a single NVIDIA GeForce GTX 780 is not enough, if you are a serious gamer. More cards is always better, so they say...
To prove it, they have continuously tried to improve the efficiency of SLI. Here, they demonstrated that two GeForce GTX 780 graphics cards in SLI mode is able to deliver an average of 75% better performance than a single GeForce GTX 780.
NVIDIA is understandably proud of GeForce Experience because they spent countless hours testing different combinations of settings for a multitude of games in order to come up with these automatic presets.
GPU Boost 2.0
Like the recently launched NVIDIA GeForce TITAN, the new GeForce GTX 780 will also feature an improved version of GPU Boost. As you all know, GPU Boost automatically overclocks the GPU by a predetermined amount if the graphics card is still operating within a defined power target - 170 W in the GeForce GTX 680 for example.
GPU Boost 2.0 changes the trigger from the power target to an 80 °C temperature target. What this means is the GeForce GTX 780 is likely to stay "boosted" all of the time, as long as the GPU's temperature remains below the 80 °C. So third-party manufacturers using a more powerful fan, or users ramping up the fans manually, can help increase the amount of overclocking GPU Boost 2.0 delivers.
