I think that the source of some of this confusion might be the origin of the
'mip' term.  I believe it first arose in the IBM mainframe world.  Data
center types love to talk in 'mips' all day, because they know little else.

Anyway, when the 780 first came out, it was found to have roughly the same
computing power as what IBM was then calling a 1-mip processor (370/145, as I
remember).  Since a VAX is significantly more CISC than a 370 (3-address
instructions, etc.), that worked out to fewer than 1 million VAX instructions
per second.
