Can We Accurately Compare XP, Vista and Windows 7 When It Comes To Performance? One writer over at the ExtremeTech web site did what I believe is an accurate, as possible, comparison of the three operating systems. The writer took a Toshiba Satellite laptop which used a Pentium 1.73 GHz processor, 1 GB of Ram and a 100 GB hard drive as his test bed. The Professional version for all three operating systems was used in order to try and make the testing as fair as possible.

The writer also installed Office 2007, Windows Essentials and Picasa 3.5 so the systems would have other software installed besides the operating system. He put the three operating systems through a series of tests which included bench mark testing. The writer also included start-up and shut down times as well.

Before reading the test results I made the following assumptions, having used all three operating systems on various computer I have in my home. Windows XP would most likely be the fastest since it is less bloated than either Vista or Windows 7. Windows 7 most likely would come out as second and Vista third.

Check out the results on all of the testing here.

After you read the test results see what you think. Were you surprised at the results? I wasn’t.

But there was one statement that the writer made that I believe just about says it all:

Windows XP actually started up fastest, but keep in mind that my test machine was built in the XP days; new machines will be more tuned for quick start-up in Windows 7.

I’m running Windows 7 on dual-core machines, with at least 3 GB of RAM or more, with sata drives, better graphic cards and overall very fast machines. Therefore I personally believe that trying to compare Windows XP against Windows Vista or Windows 7 on a machine designed for Windows XP, may not be a fair comparison.

However the writer did go on to state that:

But for the purposes of this story, testing on one of those machines would be pointless—this story’s about the experience those who are upgrading can expect. For most people, that means an older machine.

This is where some people are going to have a less than stellar experience using Windows 7 on an older box. Your system will most likely run slower using a newer operating system. Just my two cents.
