Performance in RPG

Fallout 3

The only drawback of dual-processor ATI solutions discussed today is their low minimal speed in 2560x1600 that is less than 25 fps. In all other cases they are way ahead of Radeon HD 4890, not to mention Nvidia solutions, of course.

This is where the difference in minimal performance between Radeon HD 4770 CrossFireX and Radeon HD 4850 X2 in 1680x1050 resolution is of primary interest to us. It could result from the difference in their memory subsystem organization, but we don’t see anything like that in any other resolutions, so we tend to believe that this fluctuation was caused by the manual fps rate measuring. As for the performance in general, unfortunately, Radeon HD 4770 CrossFireX application is limited to 1280x1024.
