Photoshop image processing
Although ps5bench was, as the name implies, originally intended to run on Photoshop 5, it executes perfectly on Photoshop 6, as well. Our first attempt to use Photoshop 6 with ps5bench exposed some nasty performance problems. Fortunately, version 6.0.1 remedies these problems, and ought to give the Mac freaks something new and different to chew on.

With version 6.0.1 and these new clock frequencies, the Photoshop race tightens up. In our previous tests with version 5.5, all of the Athlon systems beat the Pentium 4 boxes consistently. Not so now.

Break it out into individual filters, and you get one of the more intimidating graphs around:

You can make of that what you will. I will say one thing: you don't see too many wild discrepancies here between the two processors, even though these filters are doing a lot of different types of calculations. Yes, the clock speeds vary a lot, but these processors' performance balances are very similar.
