I didnt want to get involved...but I cant help it.

Got this from an extensive article comparing the two.  It is a reprint
from a tech journal somewhere, and can be found on gopher (somewhere) 
I've lost the info on what gopher, but will try and find it and post it.
Heres the graphs from the article.

I love it...  even for the cray's! Note that the Intel 486 is way down the
list from the '040 and '060?   Have fun, hope this doesnt stir up more of
a rats nest, but speedwise, these are the facts.  OS's?  Well, that's a
different story.....
