Even with the power of the AMD Athlon X2 and Intel Extreme Edition processors, we still find ourselves hitting a CPU limitation in a lot of our benchmarks. That is, the graphics cards have more performance to give but the processor is letting the team down.
By overclocking the processor we can see what kind of a performance increase we get. When something isn't CPU limited the performance increase isn't all that major but when we do have a CPU bottleneck, every MHz extra we can get can show us an excellent jump in performance.
The Athlon X2 3800+ was increased from 2GHz to 2.45GHz with a slight increase in the front side bus utilizing the stock X2 heatsink fan.
Even with the extra 100MHz we have pumped out on the processor we are still finding it not impacting the score all that much.
3DMark05 sees the exact same situation as above with the overclocking not helping us.
Far Cry as always sees a performance jump thanks to its CPU limitation.
