Futuremark forum has published Window vista SP1 and XP SP3 performance report.The test results that i think that quite objective.Let has a look together.
The computer spec.that he using as follows:
Core 2 Duo E6600 @ 3.2GHz (8*400)
8GB DDR2-800 4-5-4-15
GeForce 8800GT 512MB (stock) Western Digital Caviar SE16 250GB
The test item are:
1.File Copy – Vista faster than XP
2.File Extraction (using WINRAR) – Vista slower than XP
3.Program load time – Vista faster than XP obviously.
4.Photoshop CS3 ‘Retouch artist’s benchmark’ – Vista slower than XP for 1 second.
5.3DMark06 – Vista score slightly lower than XP.
6.Crysis GPU Test – Vista frame rate slightly lower than XP.
From the test results,we noticed that the performance between Vista SP1 and XP SP3 almost same in most of the testing.In program load time,Vista is excellent,due to using SuperFetch technology.( most of us don’t like this caused the memory consumption reason).
Maybe you can share the result with us if you have done this kind of performance test.
