we have K6/233's running on ICC.  they are 15-20% faster than my P6/200.
so let's call it 1.2X for simplicity.  Your 500mhz alpha is 1.5X.  I'm
to (most likely) run on a 500mhz alpha.  Am I therefore now "within the
spirit" or not???

BTW, a PII/300 can easily be 1.5X a P2/300 with the right coding style.
if the PII/300 is "on the same field" then the 500 alpha has to be
too... they
seem similar.

*EXCEPT* that crafty runs like hell on an alpha compared to a P6,
because of
all the 64bit stuff I use.  So how do we compare now?  Crafty on a P6 vs
Crafty on an Alpha?

If so, I want to compare fritz on a P6 to Fritz on an alpha.  Wait?
can't do that right?  Because of the assembly problem?  So my extra
burst of speed shouldn't be counted either in the performance comparison
I am not using assembly language...

It is *not* an easy issue to wave off as fair/unfair...
