I will never understand how or why this happens....
The OP asked a question about performance differences between different G5 systems....
And the poster indicated that they were already able to work out relative PC performances (I wish they'd write a book on the subject as I'm buggered if I can do that!) so it makes sense to give some idea of performance related to a PC baseline.
As always in these discussions it is the question itself which is at fault, you might just as well ask which flavour ice cream is the best.
In the end it comes down to what does the job better, if I'm editing Video or audio, burning DVDs, Photo-shopping or emulating nuclear explosions in real time (allright I made that last one up) I'll use the PowerMac G5, if I'm browsing the web, checking my email or doing my business accounts I'll use the iMac, if I'm playing Doom 3 I'll use the AMD-64. The best tool for the job in other words.
(Oh and I do actually have Doom3 for the Mac and it does play at full resolution and video settings on my BeastyMac but I still prefer to play it on the AMD-64 system, so much for me being Mac biased!)
So to actually answer the OP:
1) The Mini absolutely crucifies any comparable PC (i.e same form factor).
2) The iMac is awesome but you get what you pay for, the bigger the numbers the better performance iow.
3) The PMs ditto.
4) The laptops are suffering in comparison to similar spec PC solutions, why Apple allowed this to occur is anyones guess.
