I don't care about how a system 'feels', or about X performance. What I
run on the machines in the lab (and on my Lombard) is a scientific
software package for restrained molecular dynamics. The RAM requirements
are modest (with under a thousand atoms) and disk I/O isn't that much
either.
I've got a few other apps that are more integer bound, I'll need to get
some test data to get measurable run times before I can post any hard
figures.
My ranking based on the lab machines, setting the G3 to a relative
performance of 1.0, and scaling all others to the same CPU clock speed:
Pentium II/III 1.14
Celeron 1.07
G3 1.0
AMD K6 0.68-0.74 (three identical K6 in identical boards)
Cyrix MII 0.60
The first two are from dual processor SMP boxes so it's possible that
single processor ones would be a bit slower. This proves nothing (other
than you can find both faster and slower Intel processors to compare
against).
