Sapphire HD 4890 Vapor-X 2GB Review

Testing:

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 four presets at all default settings.

 Settings:

• Settings (each preset): Default
• Entry: 1024x768
• Performance: 1280x1024
• High: 1680x1050
• Extreme: 1920x1200

THe 1GB and 2GB Vapor-X cards perform almost identically through all four presets. The Vapor-X 2GB model delivers higher performance than the GTX 260s and last gen ATI cards but just cannot reach the level of the GTX275/285.
