Rule of thumb: expect to get around an 80% boost in speed for dual
processors over a single processor. So a dual 2 gHz will probably
perform approximately equal to 2 processors x 2.0 gHz x .80 = 3.2 gHz.
The G5 PowerMacs also have much better bandwidth to the processors and
a more efficient architecture so you'll see significantly better
performance due to that. As to what this means in the real world, well
here are some benchmarks:

It all boils down to the fact that the G5 is not hype, it's all about
performance. Even the entry level G5 has some pretty good benchmarks.
However, the base G5 might not be enough better than your Powerbook to
justify the upgrade. If you don't mind spending some cash the dual
2gHz or the dual 1.8 gHz are probably going to be more worth upgrading
to than the low end G5.

I just replaced a 800Mhz G4 TiBook with a new 1.5Ghz AlBook.
I was very happy with the jump in performance.
I have a script that extracts Excel data, scrubs and processes the
text in variables and then builds Illustrator charts. On the old
system, it clocked at 29:36 minutes--on the new 1.5Ghz machine the
time was cut to 13:48--That's a little more than twice as fast as the
old 800Mhz PowerBook!
Does anybody have an idea of how much more improvement a G5 desktop
might bring? I'm trying to decide between an entry level single
processor G5 and one of the dual processor models.
