Why compare hardware and software at all? Its like comparing roads and cars.
Cars even run on roads, much like software runs on hardware. ( Forgive the
awful analogy. It is deliberately obsurd. ) Even though they affect each 
others development, the technologies are very different.

Look at LRU caching and paging. This technique depends on a statistical 
property of programs in general, but to get maximum performance from a
given machine a programmer needs detailed knowledge of its implementation
on that specific machine.

Two very different technologies. Two very different points of view.
Two different cultural heritages.
