I dug two laptops out of my pile of old stuff the other day. One is a Dell Latitude C810 with a 1.13 GHZ Pentium 3 Tualatin processor. The other is a Dell Precision M50 with a 1.8 GHZ Pentium 4 processor.
I was bored and ran SPEEDSYS with a bootdisk on both machines. I expected the P4 to win because of the clock rate advantage. Much to my surprise the P3 chip won by a large margin on the CPU score.
The P4 is a northwood processor with a 400MHZ bus. Its memory bandwith kills the P3 because of DDR vs PC133. I know that clock for clock the the P4 is an inferior processor compared to the P3, but these results suprised me. I am uploading the test results; anybody have any ideas as to why the P4 lost badly?
