I suspect that these are for programs that don't break cache too much. With
the ARM2, the memory system keeps up reasonably well. With the ARM3 the cache
helps to hide the effects of slow memory, though as soon as the cache breaks
the performance drops to that of an ARM2, or slightly worse. The ARM600 gains
a write back buffer which decouples the core from memory even more, but again
if you have massive inline code you can slow the processor right down.
