e’re using the baseline scores (not the raw scores) from each benchmark, so in all cases a higher score is better. We’ve computed the MacBook Pro’s score as a percentage of the PowerBook G4’s score, and again, higher is better.
It’s worth mentioning that Geekbench is a universal binary and does not measure Rosetta performance at all.

Conclusion
The MacBook Pro outperformed the PowerBook G4 in almost every benchmark (especially the multi-threaded benchmarks). Since all of the MacBook Pro’s baseline scores are over 100, it even outperformed our baseline system, a Power Mac G5 1.6GHz! The only benchmark where the PowerBook G4 outperformed the MacBook Pro, Stdlib Allocate, depends more on library performance than raw hardware performance.
