AMD Unleashed: Four CPUs, Two GPUs, All Overclocked

Benchmark Results: Unreal Tournament 3

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.

    I just skipped to the conclusion to see if reading the whole thing would be worth it.

    Seems to me like AMD know there stuff is slower and you have to accept that you have to overclock, Or their products have huge temperature problems at higher levels, so let’s "re-brand" it over clocking and let the punter spend X on cooling.

    How much goes into over clocking equipment Vs getting a CPU that runs faster and cooler in the first place? Is that much being saved?
    /Honest question with a hint of sarcasm.

    Also - I accept that just getting a system to over clock as much as possible is a valid waste of free time and good money as any other. If you enjoy it go for it.

    Phenom II X4 is good at stock speed compared to Intel (especially games like GTA IV), and overclocks quite well. Practically any CPU of this nature (both AMD and Intel), will require focus on keeping temps down if you want a decent overclock.
