is their a huge diference in performance between the most recent powermac g4 and any new g5?

old and busted = G4
new hotness - G5

Seriously, it's no contest. If the G4 and the G5 went to prison together, the G4 would be the 'girlfriend'.

Hmmmm... PowerMac G5 DP2.5 vs a PowerMac G4 DP1.42... I'd take the PowerMac G5 DP2.5... ohhh wait, I already did. No question, the PowerMac G5 DP2.5 is alot faster, has newer technology, and has a much better motherboard architecture than the PowerMac G4.

Here are some benchmarks that XLR8 did over a year ago and shows a PowerMac G5 DP2.0 vs a PowerMac G4 DP1.25. http://www.xlr8yourmac.com/G5/Dual_g...800_tests.html

With the introduction of the PowerMac DP2.5 and the new video cards, the Radeon 9800XT and the Geforce 6800 Ultra/GT the G4 isn't even in the race.

I traded my dual G4/800 for a dual G5/2GHz is the G5 was significantly faster is everything.

OSX needs fast processors.

Dual 800 vs Dual 2.0 and the 2.0 is faster, eh?

Seriously though. If you're comparing a current high-end G5 to a final run G4, there really is no contest, the G5 is the clear winner. But if you're comparing a G5 1.6/1.8 or Dual 1.8 to a Dual 1.42 G4, the line becomes more blurred.

And if you toss things like power consumption and expansion into the mix, it gets even blurrier.

To answer your question: It depends. The G5 doesn't outright win against the G4 in every task. For some things there is a huge difference in performance, for other things there isn't. It depends on what you are doing.

I guess I mean, it was no small upgrade - the dual 2.0 was like a whole new mac, not like an incremental upgrade like when i was moving up the ranks of the G4.

Let's just say I passed on dual 1GHz, dual 1.25GHz and dual 1.42GHz and kept my dual 800 becuase I was not convinced that they were significantly faster computers in day to day use, only rendering and stuff like that.

I'd take any dual G5 over any dual G4 and I'd take a dual G4 1.25 or dual G4 1.42 over a single G5 1.6 or G5 1.8.

so a 1.5ghz G4 powerbook vs a single 1.8ghz G5? Hmm, Id say the G5 with its faster bus and memory...although the line seems to blur just a tad.

the dual 1.42 GHz G4 machine is very nice, but i would take the dual 1.8 GHz G5 (either version) over it. if it was the case of one of the single G5 machines, i would get the dual 1.42 GHz G4 instead.

I would prolly rank them like this, based on CPU alone and forgetting about the fact that the G5 can take upto 8GB of RAM, etc..

G5 1.8 single
G4 2x1.42
G5 2x1.8

If the code is both MP and G5 optimized that is.
