My brother does hardware design for the dark forces so he isn't an expert on
the PPC family but he explained it like this: given two processors where
everything is equal except one has a small L2 cache and an L3 cache while
the other has a larger L2 cache, the processor with the larger L2 cache will
run more efficiently. Then, being a typical nerd, he then provided numerous
examples where that wouldn't be true :-)
