From Maximum PC, March 2003 issue:
I'll skip the everything but the benchmarks, just to save time. All machines were dual-processor rigs with 2GB of ddr266 ram at their disposal.
Quake3 1.32 1024x768
PowerPC G4s @ 1.25Ghz: 135 fps
AMD Athlon MPs @ 2.0Ghz: 186 fps
Intel Xeon P4s @ 2.8Ghz: 290 fps
Quake3 1.32 640x480
PowerPC G4s @ 1.25Ghz: 152 fps
AMD Athlon MPs @ 2.0Ghz: 193 fps
Intel Xeon P4s @ 2.8Ghz: 327 fps
Jedi Outcast 1.04 1024x768
PowerPC G4s @ 1.25Ghz: 40 fps
AMD Athlon MPs @ 2.0Ghz: 69.8 fps
Intel Xeon P4s @ 2.8Ghz: 101 fps
Jedi Outcast 1.04 640x480
PowerPC G4s @ 1.25Ghz: 41 fps
AMD Athlon MPs @ 2.0Ghz: 68.9 fps
Intel Xeon P4s @ 2.8Ghz: 101 fps
Photoshop 7.0 MPC script
PowerPC G4s @ 1.25Ghz: 60 sec
AMD Athlon MPs @ 2.0Ghz: 35 sec
Intel Xeon P4s @ 2.8Ghz: 34 sec
Premiere 6.5 export to QT
PowerPC G4s @ 1.25Ghz: 430 sec
AMD Athlon MPs @ 2.0Ghz: 335 sec
Intel Xeon P4s @ 2.8Ghz: 328 sec
LightWave 7.5 RayTrace 8 threads
PowerPC G4s @ 1.25Ghz: 105.3 sec
AMD Athlon MPs @ 2.0Ghz: 88.3 sec
Intel Xeon P4s @ 2.8Ghz: 55 sec
I think the results speak for themselves, especially since both the Athlon MPs and Pentium4's were being limited to the G4's lower memory speed. I can't wait to see what the performance gap is when the PC world has moved on to 800Mhz DDR2.
FrostyMMB: I too have done listening tests, with about half a dozen tracks from differnent genres. I was only comparing low bitrates (128kbps cbr for mp3 and aac and q4 for ogg, which is in the low 120's usually). While the aac's sounded better on average (less pre echo, fewer stereo artifacts) the really complex tracks had nearly as many artifacts as the mp3s did. You may think I'm being biased, but I don't really care who wins and who loses. I won't ever encode at anything less than alt preset extreme for mp3 or ~196kbps for aac. The exception is ogg, which I would probably encode at q4 instead of q6 if I had a portable player with limited memory. It'd still be q6 or better for use on my computer or with a large-capacity player, though.
