Apple's new MacBooks take huge performance hit when running on AC Power with no battery connected.
Gearlog benchmarked a 2.53-Ghz MacBook Pro with 4GB of RAM using Cinebench R10's multiprocessor test, and achieved a score of 5,549 with the battery present and 3,504 with the battery removed.
Apple has documented this on their support site saying, "If the battery is removed from a MacBook or MacBook Pro, the computer will automatically reduce the processor speed. This prevents the computer from shutting down if it demands more power than the A/C adaptor alone can provide."
While this might not be an issue for those with a working battery, it is unknown how the computer will benchmark with a dead battery present.
