Wait a second, microsoft's completely arbitrary scale goes up to 7.9 now? Does anyone have any idea why they choose such random numbers?
Per wiki
"The
Windows System Assessment Tool (
WinSAT) is a module of
Microsoft Windows Vista & Windows 7 which measures various performance characteristics and capabilities of the hardware it is running on and reports them as a
Windows Experience Index (WEI) score, a number between 1.0 and 5.9 for
Windows Vista and between 1.0 and 7.9 for
Windows 7. The WEI is due to increase its maximum score with future updates. The WEI includes five subscores: processor, memory, 2D graphics, 3D graphics, and disk; the basescore is equal to the lowest of the subscores.
The WEI allows users to match their computer hardware performance with the performance requirements of software. For example, the
Aero graphical user interface recommends a WEI score of 3 or higher for satisfactory use of the "
Aero Glass" feature. The WEI can also be used to show which part of a system would be expected to provide the greatest increase in performance when upgraded. For example a computer with the lowest subscore being its memory, would benefit more from a
RAM increase than adding a faster hard drive (or any other component).
Microsoft intends that software publishers list WEI scores to specify hardware requirements instead of specific technical parameters (such as "256MB of RAM or more"). Microsoft also intends that hardware manufacturers publish the WEI scores of their computers. However, very few software or hardware vendors have done so to date.
The WEI is also available to applications through an
API, so they can configure themselves as a function of hardware performance, taking advantage of its capabilities without becoming unacceptably slow."
