I could offer two Cel-300A on a P2B-D and a PIII-800EB on a P3B-F for
comparison. NT 5.x.

Sandra has one particular drawback: Its benchmarks are 100% synthetic.
The only ones I've found to be of real use/significance are the memory
related benchmarks with buffering turned OFF.
My standard applications benchmark is the Mozilla 1.5 launching time
(with a single empty browser window - when launched from disk for the
first time, this depends on the hard disk, file system, memory and CPU
performance; this can be reduced to just memory and CPU by closing the
lizard again and measuring the time needed for a restart from the disk
cache. Some times measured here:
Machine 1st launch/s restart/s
P2B-D, 2xCel300A, 512 MiB, Cheetah 36ES 8.3 5.25
18 gig on Advance 2941U2W, NT 5.2
(Same with P2L97-DS, 448 MiB used 2 b 13 7 !!!)
P3B-F, PIII-800EB, 384 MiB, 'Cuda ATA n.m. ~2.1-2.2
20 gig on Ultra66, NT 5.0
Dell Lat. CPt C400GT w/ iBX, mCel-400, n.m. 4.5
256 MiB, Travelstar 40GNX 20 gig on PIIX4E,
NT 5.0
With the lizard running, one may find rendering a local copy of a rather
"heavy" web page a decent benchmark - say, this one I visit rather
frequently: <http://users.erols.com/chare/elec.htm>. (This one may
depend on the font and font size chosen, though. I'd recommend measuring
the time for going back to the end of the large page. That's about 14.5
seconds on the Dual Celery, according to my stopwatch. 18px Verdana.)
