Score overall when using the XBench test - higher scores (longer bars) are better. Xbench was developed to provide a comprehensive benchmarking solution for Mac OS X. Xbench is useful not only for comparing the relative speed of two different Macintoshes, but also for optimizing performance on a single machine. Xbench is accompanied by a website that allows graphical side-by-side comparisons of any out of the tens of thousands of submitted benchmarks.
