Does anyone know if Bridge in the CS4 version benefits from a dual-core processor? Those thumbnails take a loooong time. Also, if it does indeed benefit from a 2-core:
1- Does it benefit from a 4-core over a 2-core?
2- And this is a value judgement: Money is tight but am i crazy not to scrape together $200 more to get a 4-core at this date and time even if Bridge does not [yet?] benefit from a 4-core? Do you, in the next 3 years think CS could be hindered by an old 2-core? I will probably get a 12MP camera next year and i often use multiple [3]HDR exposures and often multiple layers. [I already know to get 8GB RAM].

Bridge makes use of the GPU if it is enabled in Preferences>Advanced. You can speed up preview processing by choosing to display the embedded preview.

Bridge GPU features include the following:

* Preview panel
* Full-screen preview
* Slideshow
* Review Mode

Bridge does take advantage of multiple cores on CPU. Camera Raw also can take advantage of multiple cores. I don’t have any benchmarks to point you at to see the difference and help you make the purchase call.

You probably want to ask in the Bridge forum or the Camera Raw forum for feedback and experiences. With 8 and 16 cores coming out, I don’t think your getting ahead of the curve considering a 4 core.

Thanks for your comments. No doubt CS5, CS6 will make use of 4-core CPUs. I had better invest the money now.

If you are going that path, you should take a careful look at the Intel i7.

yup. and wasn’t there a pretty thorough test recently about the diminishing returns after 4 (or was it 8 ) cores?

Hi,

I now realize I should be more precise and say that Br and Cr take advantage of multithreading support. In other words, single CPU w/multithreading, single CPU with multiple core, and multiple CPU with multiple core setups all show performance improvements compared to single thread computations.

Thanks, steve. That makes more sense.
