Windows Experience Index Score Explained

The Windows Experience Index Score was introduced in Windows Vista and used to give you a good idea of the capabilities of a computer. You can use a computer’s Experience Index base or sub score to help determine if it’s what you need when purchasing a new computer.

The Experience Index Score rates your computer’s components performance from 1 to 5.9 with 1 being the worst performing and 5.9 being the best. The score’s benchmarks were established when Windows Vista was released.

Base Score Explained

The base score represents the overall performance of your system as a whole, based on the capabilities of different parts of your computer, including RAM, CPU, hard disk, general graphics performance on the desktop, and 3-D graphics capability.

A computer’s Base Score is the lowest Sub Score (explained below).

Sub Score Explained

The sub scores are the result of tests run on the RAM, CPU, hard disk, general desktop graphics, and 3-D gaming graphics hardware components of your computer. Each component gets its own Sub score.
