I just called apple and got quoted 2.635,98€ for the base dual quad model with the student discount. According to the sales person I don't lose any privileges for using the student discount. Can someone confirm this?

-Thanks
 
+logic has a crappy multithread implementation..
right now im maxing 3 cores, 3 are at 50-60%, 1 is at 75%, and 1 is IDLING.

Exactly! The multi-core implementation in most 'pro apps' is shocking. Logic is is one of the worst offenders.

Software is the limiting factor these days. The top end 2009 mac pro is wasted on about 98%* of current software, even the stuff that claims it's optimised for multi-cores!

*ok that's a made-up statistic but it must be close ;)

@PowerPaw, can you please extrapolate your chart to include the 2007 3.0GHz Octad...?

Thanks.

not if it's BOINC or other forms of distributive/grid computing... :D

Don't get me wrong. There's a few apps out there that squeeze every last bit of juice out of the latest and greatest multi-core processors but for every optimised app there's a ton of apps that wouldn't know what to do with an additional core if it slapped it in the face.

Why don't you try benchmarking your P4 with HT turned off, then again with HT turned on, see if it doubles the performance...?
And try real-world performance test.... not just synthetic benchmarking...

Sorry, I admit my error!
Just tested - "HT off" results in 15% (far from 100%) performance gain vs "HT on", at least in Cinebench.

In the past, I notice that Brazil in 3DSMax render faster with 1 thread w/o HT than 1 thread w HT and decided "by eye" that it is faster approx. twice. It was mistake.

May be HT in Gainestown works other way?
 
If I had one of those 2.26 machines I think I'd probably buy a dual socket 1366 board when they come out and the OC the hell out of those little chips. Of course, that new case would need some re-working...
 
Right, that settles it! Im going for the 2.8 and saves a few $!

Cheers geeks for your insight!

Here you go - this really is making no sense...

Awesome mac

This mac is great. Enjoy!!!!

I just ordered 8 core 2.26, 14 gig ram, 2 tera HD, radeon 4870, 2 18x superdrives

The 8 gig RAM upgrade and 1 extra terabyte HD was ordered from OWC for only $250!!!!!

I highly recommend these types of upgrades to get the most out of this awesome machine
 
Great to see the Geekbench and Cinebench results for the 2009 Mac Pro.

In case you want to add it to your list, I have Geekbench 64 bit results for our 'early 2008' Mac Pro 3.2GHz produced a 64 bit score of 10347
(which makes the 17665 rating of WonderSausage's 2.93GHz Nehalem 71% faster for this benchmark).

And our Cinebench 10 'multiple CPU' rating is 21354
(which makes the 25644 rating of WonderSausage's 2.93GHz Nehalem 20% faster for this benchmark).
 
It's not. Sounds like he is buying 6 X 2GB (12GB) and keeping 2 of the 1GB sticks it comes with (14GB). Math is hard...

6x2GB is $220 at OWC which leaves $30 for the 1TB hard drive. Being pessimistic, I would conjecture that they went for 4x2GB ($150) and forgot to correlate this with the number of available slots.
 
Possibly but I've been testing some "software" on Snow Leopard and I can say this much. On my iMac 3.06 w/NVidia 8800GS QT-X uses about 10-18% CPU in SL. playing an H.264 960X540 video. On Leopard it uses on average 30% CPU. I'm guessing Grand Central has something to do with this not just a new Quicktime app because the memory usage is actually more in SL than in Leopard.

I doubt it's anything to do with Grand Central. It sounds more
like GPU-based decoding.

Honestly, people talk about Snow Leopard as if it's going to be
some miracle OS. Some people hereabout (not necessarily you)
should bear these in mind:

(a) Snow Leopard won't turn a single threaded application into
some super optimized multi-threaded app.

(b) Some of the advantages will require recoding. Companies
such as Adobe have been slow to use Mac-specific APIs (e.g.,
Core Image), so don't get your hopes up.
 
According to what I have read on the Adobe Forums, Grand Central was not intended for Pro applications like Photoshop. It was intended for applications with simpler requirements. In order for the Pro applications to work with multiple cores, they will still have to be coded by the programmers as they have been up to this point.
