ATI Radeon HD 2600 and 2400 Performance
After many years of development, Take-Two Interactive recently released the highly anticipated game Prey. Prey is based upon an updated and modified version of the Doom 3 engine, and as such performance characteristics between the two titles are very similar. Like Doom 3, Prey is also an OpenGL game that uses extremely high-detailed textures and a plethora of dynamic lighting and shadows. But unlike Doom3, Prey features a fare share of outdoor environments as well. We ran these Prey benchmarks using a custom recorded timedemo with the game set to its "High-Quality" graphics mode, at resolutions of 1,280 x 1,024 and 1,600 x 1,200 with 4X AA and 16X anisotropic filtering enabled simultaneously.
As you'd expect, considering both games are based on the same underlying engine, the new Radeon HD 2600 XT's and Pro's, and 2400 XT's performance in our custom Prey benchmark mirror those of Quake 4. The Radeon HD 2600 XT comes withing striking distance of the 8600 GT, still can't quite catch the GeForce.
