I saw on Macbidouille this bench :

We have performed some encoding tests with QuickTime Pro 7.0.3, Handbrake (a recompiled version supporting H264 baseline) and ffmpegX. The computer used was a PMG5 dual 2.5GHz, 4.5GB of RAM with a 74GB Raptor.

Hereafter are some results :

Source 1 : Trailer high definition Ice Age 2 (H264 1080p), time 2'15''.
With QuickTime 7 Pro in MPEG4 480px : 4'15''
With QuickTime 7 Pro in H264 320px : 13'30''

(http://hardmac.com/news/2005-11-02/#4685)

I downloaded the same trailer, and my P4 640 takes only 11'30 to encode it in H264 320px ! ( with 10.4.1 updated with 10.4.3 and Quicktime 7.0.4 )

Hi there ...

this is weird ... !!! more feedback and investigation would be good!!!!

I now did a test in OSX86 10.4.3 native+Maxxus patch
and OSXPPC 10.4.3

Hardware is:
PC: Intel 915GUX motherboard + Celeron D 2.8, 512MB DDR2.
Mac: Dual Core G5 2.0, 4.5GB DDR2.

I encoded in Quicktime from a .DV source file into H264. Same file both machines, same settings.
Quicktime OSX86=7.0.4, Quicktime PPC=7.0.3

now ... the benchamrks

PC = 10':04"
Mac= 2':25"

I don't know what is the problem but a G5 dual core 2.0 is more than 4 times as fast.
Xbench gives me on PC a total score of 58.54

I think you should do a better test with your DP G5 2.5 ....
:-)
Cheers

Can you encode Ice Age II 1080p (the trailer, available on apple.com) to 320*177 H264 ? I guess you're Celeron is too slow... I have a P4 3,2 Ghz 2 MB L2 and my Xbench is 110, so it's a lot faster... Celeron has a very very very little L2 memory (256 Ko for the Celeron D 2,8 I guess) .............. And do you have SSE3 ?

I can't believe that a P4 is faster than a dual G5 2.5Ghz. Do you realy have a G5 or do you just assume that your P4 is faster?

This is about decoding anyway...
