WorldBench
For a good look at general desktop application performance, we'll focus on WorldBench's overall score and then its individual components.

The simulated 940 comes out four points ahead of the retail product in WorldBench's overall index. We can see which tests contributed most to this gap by looking through the results below.

Surprisingly enough, the faster L3 cache of the simulated 940 is good for a slight but broad performance boost in nearly every application here. The biggest differences come in the Firefox web browser test and in the multitasking test that runs Firefox concurrently with Windows Media Encoder.
