Windows 11 – How to find the WEI performance index?
Windows 11 but also Windows 10 measures the performance of your PC. The procedure gives a score between 1 and 9.9 to different subsystems in order to evaluate the overall power of the machine.
This performance index is known as WEIcontraction de Windows Experience Index. It is established using the WinSAT utility in charge of testing the power of different hardware elements. The balance is given in the form of a number. The higher this number, the more powerful the PC.
To achieve this overall rating, WEI relies on a rating of five key areas of PC power. This includes desktop graphics power (index GraphicsScore) and 3D (index D3DScore), the memory bandwidth (index MemoryScore), the throughput of the storage unit (DiskScore) and processor power (index CPUScore).
Attention : The final score is not an average of these sub-scores but the lowest score.
