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 1024x768, progressing to 'Extreme' at 1920x1200. Of course, each preset can be modified to arrange any number of user designed testing. For our testing, I will use the High and Extreme presets at all default settings.
- Settings (each preset): Default
- High: 1680x1050
- Extreme: 1920x1200
- PhysX: "OFF"
Higher Scores = Better Performance
The GTX 295 Quad SLI combo is the highest performer in the dual GPU card class, at both the 1920x1200 and 2560x1600 resolutions. The story is the same with the dual GPU cards run in single card mode. The next class down contains the single GPU cards running in multi-GPU mode - Crossfire or SLI. The GTX 285 and the GTX 260-216 combos are at the top of this field, with the Sapphire Toxic HD 4870 1GB card in a relatively close third position. The Nvidia cards are easily the top performers in this benchmark, much the same way the ATI cards are in the 3DMark06 testing.
