MIPS are irrelevant.  A single instruction on the Cray could operate on a long
series of things, like a chess board.  And the first Cray built had at _least_
ten times the memory bandwidth of the fastest PC built today.  1983 crays could
beat todays best PC by a factor of 1000 in moving stuff thru memory...

there is more to it than meets the eye...
