Is there a guide on the metrics required to obtain a certain Windows Experience Index?
A Microsoft guy said in January 2009:
On the matter of transparency, it is indeed our plan to disclose in great detail how the scores are calculated, what the tests attempt to measure, why, and how they map to realistic scenarios and usage patterns.
Has that amount of transparency happened? Is there a technet article somewhere?
Best Answer
If my score was limited by my Memory subscore of
5.9
. A naive person would suggest:Which is wrong of course, it is simply not only about faster but also about more.
From the Windows help:
You can buy the fastest, overclocked, liquid-cooled, DDR5 RAM on the planet; you'll still have a maximum Memory subscore of
5.9
.So in general the knee-jerk advice "buy faster stuff" is not helpful. What i am looking for is attributes required to achieve a certain score, or move beyond a current limitation.
The information i've been able to compile so far, chiefly from 3 Windows blog entries, and an article:
Memory subscore
Graphics Subscore
Gaming graphics subscore
Processor subscore
Primary hard disk subscore (note)

You can find your WEI detailed test results in:

Fine, how do i increase my hard-drive's random I/O throughput?
Update - Amount of memory limits rating
Some people don't believe Microsoft's statement that having less than 4GB of RAM on a 64-bit edition of Windows doesn't limit the rating to 5.9:
