The benchmark speed, beside varying over time, is not a metric of true performance. Average execution time of actual Work Units is the only valid measurement of performance.

Hi, Flashdrive. I've got the same exact iBook and your numbers are close to what I got when I first started to run MenuBar. 627/1971. After a couple of days, I changed the BOINC app in menu bar to the Team MacNN optimized one, and my numbers are now:
Measured floating point speed 909 million ops/sec
Measured integer speed 2146 million ops/sec

I hadn't thought of the optimized BOINCs! Lemme download the G4 version...

1.33× faster floats, but 1.04× faster ints. I think the larger L2 and clock speed is what's giving me a slower float rating than Flashdrive and C.

Either way, as soon as I can get my hands on a G5 mobo that fits into a Mac Plus case and I swap the CRT for an LCD... [drooling]

I'd like to know more about the G5,and dual CPU G5.Really considering the desktop.Also hear the Mac Mini rocks.Seen not bad reveiws for a McMini for under 800 bucks.

The only shortcomings on the Mini are:
    <li>It's a G4</li><li>It's got one DIMM slot</li><li>Core Image won't run, let alone Core Video</li>

I've been looking over the Mini take-apart, and I have to figure out a few things (rewiring the Mini's power button to a hard on/off switch, fitting the power adapters into the case, hooking up the LCD in confined quarters, and making the ports accessible from the back of the Plus's case). I'm hoping that Apple will be putting out a G5 Mini alongside Tiger, but it'll be a week or so before I know for certain how I'll go about it.
