Then I installed the new 10.2.8 update (I waited) and immediately ran XBench again, and got an 80.66 score, reporting "PowerPC G4 @ 667 MHz" for processor.
After this, I ran Apple System Profiler, which states machine speed to be 1.0 GHz.
Looks like the update tricked XBench, but it also looks like everything scored a tiny bit lower across the board now that I've installed 10.2.8, even though some things like window draws do *seem* a bit faster.
I have to say I'm concerned about this magical battery life extension that seems to be going around. Since I got this TiBook, I'd get a pretty consistent 2:45 fully charged, but after updating to 10.2.8, it spiked out at 5:40, spent some time in the 4-hour range, and at the moment seems to be jumping around between 1:50 and 3:10 (because I'm using it). Is this just a clever trick, or is it using more advanced CPU throttling techniques or something?
