+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.
New and Improved! Now With 2007 Mac Pro 3.0 Octad!

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![]()
not if it's BOINC or other forms of distributive/grid computing...![]()
Here's my 2007 3.0GHz Octad if there's anything worth contributing:
Rendering (Single CPU): 3245
Rendering (Multiple CPU): 18885
Multiprocessor Speedup: 5.82
@PowerPaw, can you please extrapolate your chart to include the 2007 3.0GHz Octad...?
Thanks.
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...

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 never knew 2x4GB could be that cheap!
Right, that settles it! Im going for the 2.8 and saves a few $!
Cheers geeks for your insight!

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...
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.
Can it run mixed Dimms?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...
