A PowerMac with 250MHz 603 is not a particularly fast mac either, nor a
200MHz 604 based one, they are OK but not much more. Anyways, the major
reason why amigas are slower is simply becasue we have slower hardware in
general, and the fact that current powerup cards dont have second level cache.
Reason why they dont have L2 cache is because the m68k and the ppc share memory,
datas cannot be stored in caches as the other cpu then wouldnt know how to
address them.
