Performance Comparison: G4 vs. Core Duo

Before I get to the actual numbers comparing my PowerBook G4 1.5GHz to the MacBook Pro 2.0GHz, I should say that actually using the machine felt a lot faster. Just scrolling through a Finder window is so much faster on the MacBook Pro than on the old G4. Everything is a lot more responsive and the system as a whole feels desktop-fast. That being said, I can't get away without putting it to the test so here we have it - a PowerMac G4 1.5GHz vs. a MacBook Pro 2.0GHz.

Both systems are configured the way they were from Apple, with 1GB of memory but the original hard drives in each. Obviously the MacBook Pro has an advantage there because of its newer hard drive, however most of my tests aren't very disk bound minimizing the impact of differing hard drives. First off, we've got the good ol' boot test:

System Boot Performance

The MacBook Pro boots much quicker than the old PowerBook G4, much like the iMac Core Duo boots faster than the iMac G5. While the PowerBook G4 boots (from power on to desktop fully loaded) in just under 50 seconds, the MacBook Pro does it in just over 30 seconds. Although personally I keep my notebook on almost as much as my desktop, boot time is important for traveling where I'm constantly turning my machine on and off.

Just like in my iMac Core Duo review, wherever benchmarks/applications were multi-threaded I tried turning off the second core on the MacBook Pro to give you a good idea of what a Core Solo would be performing like up against the PowerBook G4. Not only is this interesting to look at, but there's also a good possibility that the future iBook replacement will have Core Solo as a processor option. The first two tests here both happen to be multi-threaded so you'll see results from both the Core Solo and Core Duo setups.

MP3 Encoding Performance - iTunes 6.0.2

The MacBook Pro is ridiculously fast compared to the PowerBook G4 in converting MP3s using iTunes: the encode time is around 35% lower on the MacBook Pro. Disabling one of the cores does significantly level the playing field, although the Core Solo at 2.0GHz still manages to be a bit faster than the G4 1.5.

H.264 Encoding Performance - Quicktime Pro 7.0.4

Under QuickTime we see a full 50% increase in performance over the PowerBook G4. If you disable the second core, the G4 1.5 actually pulls ahead of the Core Solo 2.0. The PowerBook to MacBook Pro upgrade, purely from a performance stance, is looking very impressive already.
