P4-2.53GHz - Linux File used for Testing: test.wav, 272,692,456 bytes Bzip2: bzip2 -9k test.wav user 4m31.960s Gzip: gzip -9 test.wav user 1m45.430s GCC (Crafty 19.1 compile time): make user 0m21.840s Lame MP3 encoder: ./notlame -q 0 -V 0 --new-vbr test.wav bench.mp3 2 minutes, 27 seconds. -------------------------------------------------------- XP-2.5GHz - Linux File used for Testing: test.wav, 272,692,456 bytes Bzip2: bzip2 -9k test.wav 2m8.690s Gzip: gzip -9 test.wav 0m22.770s GCC (Crafty 19.1 compile time): make 0m15.290s Lame MP3 encoder: ./notlame -q 0 -V 0 --new-vbr test.wav bench.mp3 1 minute, 19 seconds. -------------------------------------------------------- Now, to put these results in perspective... In GCC it would take a P4-3618.09MHz to equal the XP-2507MHz. In GCC it would take a XP-1755.12MHz to equal the P4-2533MHz. In Gzip it would take a P4-11728.33MHz to equal the XP-2507MHz. In Gzip it would take a XP-539.77MHz to equal the P4-2533MHz. In Bzip2 it would take a P4-5445.94MHz to equal the XP-2507MHz. In Bzip2 it would take a XP-1166.04MHz to equal the P4-2533MHz. In lame it would take a P4-4713.30MHz to equal the XP-2507MHz. In lame it would take a XP-1347.29MHz to equal the P4-2533MHz. ----------------------------------------------------------------- I'm sure you're thinking, "What the %(&#(*". This is why if you'd like, Tom, you can telnet into my Athlon XP machine and run the exact same tests (or any other tests you wish to run), as well on the Pentium 4 2533MHz machine.
