When we test a new processor at Trusted Reviews we tend to have a good idea what we’re looking for. A Pentium 4 that increases clock speed from 3.2GHz to 3.4GHz is likely to raise CPU performance by six percent, which may in turn raise system performance by one or two percent. Bumping up the FSB, L2 cache or system memory speed should also raise performance but as we’ll be looking for a small percentage increase we find that the best way to amplify the gains is to run test software that is limited by the CPU. Video rendering is ideal as it drives the processor flat-out and uses all the clock cycles that you can throw at it. Therefore, if you really want to see the benefit of your new processor we suggest that you run POV-Ray, Nero 7 or Windows Movie Maker.
