Another area worth some study (in terms of "usable" architectures) is 
"balance".  Any rough guesses (order of magnitude) on what the memory and
io bandwidth of a Cray X-MP 48 is?  An IBM 3081K?,  A Vax 8600?,
A VP200?, An FPS 164?, A Cyber 205?, A Hep?,  A Hypercube?.  Perhaps 
mips are a measure of intelligence and machine bandwidth a measure of
muscle - here again, large, untunable benchmarks (e.g. MSC/Nastran) are
hard to top when it comes to comparing architectures.

(a teaser - which of the above can support io traffic in excess of 20gbit/s
and maintain rated cpu speeds?)
