Eh well my laptop is dying, so I had the occasion to install fedora
core2 on my old amd k6-2 300Mhz.
So here is the speed result:
-O3 -funroll-loops -march=k6-2 -mmmx -m3dnow
Rate Name (* machine default)
207145 ANSI Compact 1-pipe
189855 ANSI Standard 1-pipe
188927 ANSI Compact 2-pipe
180969 ANSI Standard 2-pipe
429635 AMD64/x86 MMX Compact 1x2-pipe
397265 AMD64/x86 MMX Standard 1x2-pipe *
so 429635 for a 300Mhz cpu vs 3741983 for a 3.06Ghz cpu is a factor of
8.7 slower but a factor of 10.2 difference in clock rate. AMD k6-2 is
doing not bad for a 2 generations older 1/10th clock rate cpu.
