Apple charges 500.00 extra to get an 8-core MP over the 4.

Any real-world advantage for audio use?

TIA

Currently Digital Performer is the only app that I know that properly takes
advantage of the 8 processors. Logic, Pro Tools and Nuendo all run better
on a 4-core. This will change soon, but an 8-core requires more RAM before
you see the benefits. Cockos Reaper runs very fast using all 8 processors
under boot camp.

Despite the fact that DP uses all 8 processors correctly, Logic is more efficient
on a 4-core than DP is on an 8-core. Apple should have an update for Logic
soon that properly shows off the power of an 8-core. Digi seems to be in
no hurry to show off the potential of all native power!

I�m still running out of power, even with 8 :-( One reason...I have completely
fallen in love with Flux plugs, but they use up a computer in a hurry.

Sure, you can mix a five minute song in only two-and-a-half minutes.

On the subject of Reaper - you can now get their plugins
in a bundle ported to VST...

.... and, yep - they're free.

Seems that even with OS X not a lot of apps are really multi-treaded enough.
Read the section about AE

http://www.barefeats.com/octopro4.html

in which you have to turn on another switch to use the extra cores but it
makes a _real_ difference.

From what I read (and in my experience in the enterprise space where 8/16/32
cores have been common for years, as well as 64 bit kernels and filesystems)
the desktop apps haven't been tuned for serious mutliprocessing yet. For
the time being I think it will be more of an app by app thing than a general
improvement in overall performance.

Using multiple apps simultaneously should see a greater increase in performance
(if you run eight apps that are one thread each and they each can have a
whole CPU that can make a MASSIVE difference in both performance and 'feel'
of the machine). It's not uncommon in Unix land for one core to be completely
pinned and non-responsive doing some job while the apps running on the other
cores feel snappy as can be.

Note also in those tests was toad's the G5s look like in comparison.
