Windows Vista Performance Index
We had a look at the integrated benchmarking tools of Windows Vista in our articleVista - Benchmarking or Benchmarketing?. The conclusion was simple: Vista's performance indices allow you to get a rough performance rating, but as you will see in our results, they do not replace traditional benchmarking. If you pick any application you will find much larger performance differences than the Vista Performance Index suggests.
Obviously, Windows doesn't require much memory bandwidth. All systems offer dual channel memory, which provides plenty of memory bandwidth and mostly satisfies the integrated Vista benchmark.
Only few processors reach the maximum score of 5.9 points.
