Benchmarks - Graphics Card Overclocking
The internal core and memory speeds of graphics cards (and for that matter, motherboards and CPUs) which hit the shelves have been carefully tested by the manufacturers for stability and longevity. They're not going to give you something designed to burn out in six months. However, this often means that there's quite a bit of room to make some improvements - enter GPU overclocking.
The weapon of choice for overclocking ATI chipsets is undeniably ATITool. We used the auto-overclocking feature, and thanks to the impressive performance of the IceQ cooling unit, the card was able to be aggressively overclocked to a core speed of 480MHz and a memory speed of 445MHz or 890MHz DDR (increases of 20% and 21% respectively). Not surprisingly, the resulting boosts in benchmark performance were pretty substantial.
3DMark03 and 3DMark05 demonstrated performance boosts of 18% and 24% respectively - pretty impressive for such demanding applications.
