The ASUS EN7900GS Top is 2-5fps slower than the EN7950GT throughout this test, their average frame rates ranging from 55 to 90fps. They see the back of the Radeon X1900 XT in front of them, but the overclocked EN7950GT is quite competitive against that Radeon, too, especially in resolutions of 1600x1200 and lower. The difference is 10% in favor of the AMD solution in 1920x1200.
The general picture is the same on the Research map, with minor deviations. The Radeon X1900 XT has a bigger lead in high resolutions due to the specifics of the map that puts a high load on the GPU’s computing subunits.
In the FP HDR mode there is almost no difference between the EN7950GT and EN7900GS Top in resolutions above 1280x1024. They must be limited by their memory subsystems.
This mode can’t be used for practical play in high resolutions, but both graphics cards from ASUS provide a high enough speed in 1280x1024.
