platform2:
tmc mvp3 board with 2mb cache
k6-3+450 oc 550(100fsb)
same geforce2ultra
same 256mb samsung pc133 sdram
win2000sp4

you can see that they were running different OS, as it was meant to be a quick test so i was too lazy to spend time installing win2000 on the cubx, so its not a fully unbiased contest. however, i believe that difference had actually given the loser a slight advantage.

i only ran 3 benchmarks:
superpi(1m digits)
celeron took 4:48, k6-3+ took 5:00, celeron has 4% lead.
3dmark01(1024*768*32 default test)
celeron scored 1630pts, k6-3+ 1550 pts, celeron has 5% lead.
quake3(640*480*16, medium quality)
celeron scored 9.6fps, k6-3+ 6.5fps, celeron has almost 50% lead.
