Mobility Radeon Vs. GeForce M: The CrossFire Advantage

Benchmark Results: Modern Warfare 2 And Crysis

Intel’s flagship Core i7-940XM can’t feed data fast enough to a pair of Mobility Radeon HD 5870s, chopping Call of Duty: Modern Warfare 2 performance at 112 frames per second. Slightly less CPU overhead allows the GeForce GTX 480M to break past it at 720p. But all solutions are fast enough to push the screen’s native 1080p resolution.

Nothing more than a single Mobility Radeon HD 5870 is needed to play the game, even with AA enabled. AMD's CrossFire’s configuration at least looks better in the charts.

Crysis is the first game that we expected would actually need the second Mobility Radeon HD 5870. We had to drop it to “High” details just to make the other systems playable, and the CrossFire configuration pushes these same settings to 49.5 FPS at the screen’s native resolution.

Very High settings could have been an option, but not with AA enabled. We don’t want to play at 720p if we don’t have to, and many of us would rather give up AA than sacrifice detail levels.
