In X-bench the MacBook performs very well. In most tests it outperforms last year's unibody MacBook. Only its slower memory lets it down, but it's still a very good all-rounder performer.
Our video encoding test shows the difference between the MacBook and the new MacBook Pro. Even with just 0.13Mhz difference between them the Pro is some 100 seconds faster.
While battery isn't quite as impressive as on the new MacBook Pro, it's still pretty decent. In normal use you can expect around four and half hours or more.
