Of course, in the "real world", there are many other considerations
to systems design other than processor speed and the "my CPU can beat
up your CPU" arguments that are familiar to us from our schoolyard days
(and seem to continue interminably here.)
This is, for example, why the number of 8051-descended CPU's that have
been shipped in the past 20 years is in the billions. (OK, very low
billions, but it's there.) (1 billion == 10**9, to not confuse the
folks who were educated outside the US of A.)
