Can C1 PRO take advantage of all cores of the new Quad-Core Intel Xeon "Nehalem" processors in one and two chip configurations? Guessing it can but want to check before possibly taking the plunge...

I very much doubt it.
Phase have not yet cracked the present and past ones yet...... see latest update 4.6.2 to improve 4 and 8 core stability.0 -
The i7 processor is basically a 4 Core processor with Hyper Threading, making 8 Cores available for the operating system.
Capture One will take full advantage of every available core.0 -
So, in a dual processor configuration I will have 2x an i7 Quad Core 'Nehalem' with Hyper Threading which will result in a total of 16 logical cores. Hmm, I losing track I am afraid or getting to old for this... 😉 0 -
Yes!
2 x 4 x HT = 16.
But will never perform as well as 2 x 8 or 4 x 4.0 -
Hi
Am considering buying a new Mac Pro tower this week.
8Core (2 x quad-core intel xeon nehalem).
1- Which processor is recommended 2,66 or 2,93Ghz (2,93 is more than 1000 euros more)?
2- How much RAM: will 8Go do?
I think I will get ATI Radeon card to use with 2 Quato or Eizo 23" monitors.
[b]I am mostly wondering about the processor if it is worth paying for the 2,93Ghz v/s 2,66ghz? RAM can be increased later but not the processor...[/b]
Help!!!
Thank you !

Yes I can vouch for this and phocus (can I say that here?) run on all available cores. Photoshop however is another matter.

I am looking around for a new Mac Pro as well. I'll can give you an inside in my orientation process. Note that not much hard boiled facts are available although Bare Feats comes with valuable information. These are some of my considerations, use what you like, neglect the remaining thoughts. 😉
Which model, the 1x or 2x Quad-Core? Regarding number of cores, I am skeptical about whether my applications (let's say Capture One and Photoshop for the sake of this thread) will use all cores. Photoshop definitely not. Note that each core of the new 'Nehalem' processor is hyperthreading, effectively presenting the double amount of cores to the application. Another advantage of the 1x processor model is that selecting the fastest (2.93 GHz) processor is an less expensive exercise and that will sure improve performance, although slightly, over standard processor type.
Amount of RAM is limited to 8 GB in the 1x Quad-Core model, but that will do for my purpose. Because the system can use triple channel mode when 3 modules are set (3x 2 GB = 6 GB) 6 GB will give the best performance but according to tests you won't note the difference with 4x 2 GB.
Regarding the video card the standard GT120 card will be fast enough for photography purposes (I am not a gamer, not a 3D specialist, nor Final Cut Pro dude) and it allows for 2 large screens to connect, up to 30". Note that the faster and more expensive ATI HD 4870 has the same amount of memory (512 MB) and support the same number of screens and sizes. You need a MiniDisplayPort-to-DVI adapter for the second screen in both cases.
A second hard disk might be a good idea performance wise. Either to separate OS X and data, or use the second as Photoshop scratch disk.
Note: what is really missing here are some Phase One supplied benchmarks for the hardware discussed here for their high-end customers.0 -
Running the new MacPro Nehalem 8core 2.26GHz.
C1 4.7 uses all 8 (16) cores equally.
Photoshop CS4 uses 1 (2) of the cores.
As to the question "small" Nehalem with more clock speed or the "big" one with more cores but less clock speed ... note that the ammount of RAM is restricted in the small one. In the 8core 2.26GHz you can mount 32GB RAM.
"Snow Leopard" (resp. "Grand Central" as part of Snow Leopard) will optimize hyperthreading so that the number of cores will have much more effect (at least that's what they promote as far as I get it all right).
So currently the faster processors, though with less cores, will perform faster. But with the upcoming OSX update the number of cores will be more important as their clock speed.
Too, hopefully future updates of Photoshop will take effect of mulit cores as well...0
