Featuring all-new game tests, this benchmark is for use with Vista-based systems. "There are two all-new CPU tests that have been designed around a new 'Physics and Artificial Intelligence-related computation.' CPU test two offers support for physics related hardware." There are four preset levels that correspond to specific resolutions. "Entry" is 1024 x 768 progressing to "Extreme" at 1920 x 1200. Of course, each preset can be modified to arrange any number of user designed testing. For our testing, I will use the four presets at all default settings.
- Settings (each preset): Default Testing
- Entry: 1024 x 768
- Performance: 1280 x 1024
- High: 1680 x 1050
- Extreme: 1920 x 1200
Higher = Better
At stock speeds the HD 6990 delivers a higher level of performance at the lower resolutions while in the upper resolutions the higher clock speeds of the pair of 6970s perform better. Again you can see the SLI configurations doing very well, holding the top spots except for one resolution where the 570's finish in third spot.
