Any such number is meaningless, unless it was obtained by timing the actual
application(s) that you care about.  The 65* series pipelines instructions,
whereas the 68K family has generally more powerful instructions.  On an Apple,
peripheral (slot) I/O cannot proceed except at a 1MHz clock rate, since some
controllers depend on this for timing.
