GTX 680 to have higher computer performance than HD 7970

In a report by 3D Center it is alleged that if the HD 7970 is used as a base score then the GTX 680 is 17% better at compute tasks. However, the GTX 680 seemed to fall away from the HD 7970 in the other tests. The HD 7970 has 4.46 TFLOPs of single precision floating point therefore the GTX 680 has around 5.22 TFLOPs if the predictions are indeed correct. But as you can see it is by no means a clean sweep of everything from the GTX 680, the other categories: Memory bandwidth (red), ROP performance (yellow) and texture performance (light blue) all show that the GTX 680 falls behind both the HD 7950 and HD 7970.

What is important to note about this is that these are hypothesized predictions based on a compilation of specifications and leaks. Also that there is no idea yet of how those results will transfer over into real work 3D gaming performance, although the high compute performance would suggest a significant win over the HD 7970 when it comes to Direct Compute related applications.
