Not really. They are both based on the same chipset and based around a Cortex-A8 CPU core. Apple's A4, of course, was designed to concentrate on power management and battery life, which never seems to be a Samsung priority.

Neither is 'better' than the other, just different.
Though of course, the iOS devices actually have high quality games and the like which make use of the power of the chip, unlike some of their competitors...
I imagine the A5 will again focus on power management and battery life (though with obvious boosts in terms of CPU and GPU).
