2D Imaging Performance with PowerNow!
More processor intensive applications such as those that deal with 2D Image Editing won't offer as much time for PowerNow! to be able to clock down to a lower speed for too long, but let's see how well leaving PowerNow! on its Automatic setting performs.
No difference here under Photoshop 5.5, so far so good.
There is a small 2% drop in performance in Auto mode however you're not going to be able to notice a drop that small. Notice that when PowerNow! is running in its Max Battery Life mode the performance is less than 1/2 that of the other two operating modes. It seems like optimizing power usage for a single, low clock speed is only a real option for business applications and net browsing.
We get similar results under Elastic Reality, an image morphing package.

PowerNow! - a very clever idea back then to dynamically adjust cpu freq & VID output. The same idea still exists in today's day and age. No wonder where did intel took the inspiration from.
