Beta is the new black for Adobe, and it fits them well. In the 72 hours after its surprise announcement, Adobe reportedly had more than 100,000 downloads of the Intel-native beta of Photoshop CS3. As a result, the Web has been abuzz with first looks and tutorials (Ben Long wrote a CS3 first look for us last Friday.) I have been playing with the beta for a while now, and it’s been a blast. I feel like a kid on Christmas morning with a new toy.

While I’ve been playing, the guys in the Macworld Lab—Jim Galbraith and Brian Chen—have been busy testing Photoshop CS3 on a few Intel Macs and some of the last generation of PowerPC-based Macs. As you would expect, Photoshop CS3 shows some pretty significant speed increases over the Rosetta-emulated CS2 on the Mac Pro and MacBook Pros.

We ran three basic tests:

  • Launching Photoshop CS3 with a 50MB file;
  • Running our standard suite of 14 scripted tasks on that 50MB file; and
  • Running a batch suite that executed three tasks (rotate, resize and save) on 100 stock photo images.

In all the tests. the Intel Mac (Mac Pro and MacBook Pro) beat its corresponding PowerPC cousin (Power Mac G5 and PowerBook G4), although the four PowerPC cores on the Power Mac G5 kept that machine pretty close in overall speed to the newer Mac Pro.
