Using the MacBook Pro normally doesn’t feel all that speedy; things feel a bit more peppy, but nothing mind-blowing. However, I did a few tasks in iMovie to see how much difference it makes to use a Universal application on the Intel machines (versus having an app written for PowerPC run through Rosetta). I compared the following actions using my main 1.25 GHz PowerBook G4, the 2.16 GHz MacBook Pro, and my dual-2.3 GHz Power Mac G5 (that’s the dual-processor, not dual-core, model).
Applying Glass Distortion Filter on a 06:17 clip in iMovie:
MacBook Pro: 14 seconds
PowerBook G4: 24 seconds
Power Mac G5: 16 seconds
Adding Zoom title of 05:28:
MacBook Pro: 13 seconds
PowerBook G4: 25 seconds
Power Mac G5: 12 seconds
Render iDVD project as disc image:
MacBook Pro: 11:56 am to 12:02 pm (6 minutes)
PowerBook G4: 12:06 to 12:22 (16 minutes)
Power Mac G5: 11:58 am to 12:04 pm (6 minutes)
I didn’t expect the MacBook Pro to equal the performance of my big-iron G5 (I’m sure the results aren’t as impressive against the latest Power Mac G5 Quad, however). Of course, that’s just using iMovie HD 6 and iDVD 6 – you’re not going to see results like that using non-Universal software such as Adobe Photoshop.
