Though Windows 7 edged out Vista in our lab tests, you may not notice much of a difference.
Improving performance is one of Microsoft's design goals with Windows 7, and many early reviewers have said that the new OS seems peppier than Vista.
But tests of the Windows 7 Release Candidate in our PC World Test Center found that while Windows 7 was slightly faster on our WorldBench 6 suite, the differences may be barely noticeable to users.
We loaded the Windows 7 Release Candidate on three systems (two desktops and a laptop) and then ran our WorldBench 6 suite. Afterward we compared the results with the WorldBench 6 numbers from the same three systems running Windows Vista.
Each PC was slightly faster when running Windows 7, but in no case was the overall improvement greater than 5 percent, our threshold for when a performance change is noticeable to the average user.
The largest difference was 4 points--102 for Vista versus 106 for Windows 7 on an HP Pavillion a6710t desktop. Our other two test machines showed similarly minor performance improvements:
A Maingear M4A79T Deluxe desktop improved by 1 point (from 138 on Vista to 139 on Windows 7), and a Dell Studio XPS 16 laptop improved by 2 points, from 97 on Vista to 99 on Windows 7.

Well one of the things to consider is that on lower end systems that have to run XP because the older hardware is slow on vista, win 7 performance is much closer to XP and certainly better than vista on these lower end systems.
