AMD QuadFX Platform & FX-70 Series Processors
Quake 4: Low and High Resolutions
For our next set of tests, we benchmarked all of the test systems using a custom single-player Quake 4 timedemo. Here, we installed the game's official v1.3 point release which is SMP capable, turned the resolution down to 640x480, and configured the game to run at its "Low-Quality" graphics setting. Although Quake 4 typically taxes today's high-end GPUs, when it's configured at these minimal settings, it is much more CPU and memory bandwidth-bound than anything else.

Low-Resolution, Low-Quality testing with Quake 4 showed a marginal performance decrease on the QuadFX platform, likely due to the non-unified memory architecture and the increased latency that comes with it.
The same holds true on the High-Resolution, High-Quality tests. Here we raised the resolution to 1600x1200 and enabled anti-aliasing and anisotropic filtering, and yet again the QuadFX platform failed to outpace its dual-core counterpart, the Athlon 64 FX-62, let alone any of the Core 2-based machines.
