PCMark is a multipurpose benchmark, suited for benchmarking all kinds of PCs, from notebooks to workstations, as well as across multiple Windows operating systems. This easy-to-use benchmark makes professional strength benchmarking software available even to novice users. PCMark consists of a series of tests that represent common tasks in home and office programs. PCMark also covers many additional areas outside the scope of other MadOnion.com benchmarks.
If you look at the individual tests you can see that the results do not carry that much except when it comes to the graphical tests. Here Windows XP clearly takes the lead and it results in the PCMark scores being different from each other.
