PPC vs x86 speed/performance comparions?

[StormLord]

The P4 is pretty lame... The G5 will be at least as fast if not quite a bit faster... If you had an Athlon64 or a CoreDuo then they would piss all over the G5

CoreDuo yes its faster but...

Athlon64??? maybe you mean the AthlonX2 ??

because my brother has an Athlon64FX@3200Mhz and I have a DUAL1.5Ghz G4 and I am 2 times faster in almost everything....
ofcourse athlon is running WinXP64 and I'm running OSX, but I don't think that an OS can make such a difference anyway...

EDIT: I think in INTEGER mulithreaded operations we must be at about the same speed, but in video encodings like H.264 and renderings I'm about 2x faster..
maybe thats because of 4 altivec units that my machine has..(2 altivecs per cpu)

What video cards are you using in the two machines?

Dammy

Actually I use an Ati X850XT and my brother a miserable Nvidia 5200FX
but renderings have nothing to do with graphic cards!!!
well in preview mode or realtime FXs preview like some from imovie yes. but exporting to dvix,H.264 or any other format has NOTHING to do with GFX cards..

If someone has any cross platform benchmarking tools they would like me to run, I would be happy to and will publish the results. (I also have a 3Ghz P4 as well

even crossplatform benchmarking can't show the real difference and that because most of them are optimised and builted for one type of machines and just crossed compiled to the other, instead of rewriting the program from scratch to take care different architectures.. also different architectures can have very different results in different tests
Example: try to run distributed net OGR to that single 1.5Ghz G4 and OGR on that 3200AMD, both cores are written from scratch for the specific CPUs , results:
G4 will be about 3-4x faster than the athlon, but that is not true in everyday tasks performance
