That, and instructions/second.  The IBM S/370 model 158 was a true 1
MIPS machine.  The VAX-11/780 executed about 500 KIPS.  But the 11/780
and the model 158 were almost a dead heat when it came to the
execution speed of real world applications.  Why?  Mainly because the
VAX architecture was a lot CISC-ier than S/370, which was basically a
load/compute/store architecture.  The VAX got a lot more done with
each individeual instruction than the S/370.
