GeForce GTX 660 2-Way SLI outperforms the GeForce GTX 680 and Radeon HD 7970 GHz Edition
A few weeks ago we received a curious announcement touting amd CrossFireX technology, where they explained the superiority of two video cards Radeon HD 7800 Series (7870 and 7850) in 2-Way CrossFireX mode before GPUs Nvidia GeForce GTX 680 and 670 respectively. From Tech AlienBabel review where we get a taste how they behave two geforce gtx 660 in 2-Way sli mode.
AlienBabel tech, like other sites like PC Games Hardware and Computerbase, prioritizes high quality graphics that is capable of providing the video card, so resort to manually adjust the drivers to ensure that they provide the highest quality visual, but this results in their test are not comparable across GPUs from different manufacturers, as not all will allow you to disable all optimizations driver (AMD Catalyst drivers allow completely disable driver optimizations, while Nvidia does not allow do).
Having said this we’ll post some of the tests performed by AlienBabel Tech:
The two GeForce GTX 660 scale quite well in SLI performance showing on average 79% higher than one of them, plus achieve a yield 35% higher than a GeForce GTX 680. Unfortunately we can not say for sure because AMR outperform the Radeon hd 7970 GPU Edition GHz (in this review one overclocked HD 7970), given the various settings for both brands in the graphics driver, but we have no doubt that if they pass .
