One of the claims that Microsoft makes about Windows 7 is that it performs better than Windows Vista. Riddle me this, then… why does the Windows 7 Experience Index for the same PC differ so radically under the different operating systems? The following images were snapped on the same hardware, but booted with either operating system.
These are the Windows 7 scores.
These are the Windows Vista scores.
Windows 7 rates the processor and memory higher than Windows Vista, but the 3D performance and hard disk transfer rate lower.
It’s a mystery.
