Benchmark Results: Unreal Tournament 3

AMD Unleashed: Four CPUs, Two GPUs, All Overclocked

3D Games: Unreal Tournament 3

Clearly the CPU is our limit here, as there is a massive amount of scaling seen. The quad-core Phenom X4 9950 BE easily bests its dual-core sibling. Even so, the Athlon 7750 BE still delivers playable performance at all resolutions.

Again, we see playable performance for each processor with AA and anisotropic filtering (AF) forced in the drivers. The main difference here is that the GPU is also limiting performance, as seen in the lower frame rates and tighter spacing of the processors at higher resolutions.

It comes as no surprise that adding another Radeon HD 4870 GPU does nothing for our performance at these settings. What is a bit disturbing, though, is that we actually see a slight performance drop at times. Is there some sort of CrossFire inefficiency under CPU-limited test scenarios?

The mighty Radeon HD 4870 X2 isn’t fazed by the added demands of forcing 4x AA and increased resolutions.
