So that means Athlons have a relatively LARGE cache?
To make faster CPUs, Intel put the clock frequency up. Recent AMD chips operate at lower clock frequencies than the number would suggest (eg my XP 1700+ runs at around 1.47GHz), and so have to get their speed boost from somewhere else...
To be certain my original CFLAGS was "-march=athlon-xp -O3 -mmmx -msse -m3dnow -mfpmath=sse -pipe" which I changed to "-march=athlon-xp -O2 -mfpmath=sse -fomit-frame-pointer -pipe". Come to think of it the performance gain may be due to the omit-frame-pointer flag. Comments?
I'm pretty sure -O3 includes omit-frame-pointer by default...
