Benefits brought by dual core processors
Based on the fact that dual core processors are basically aimed at improving multi-task treatment, it is not clear to me which choice is the best for working with Premiere Pro; either a dual core or a single core having a higher frequency (for instance the AMD 64 X2 with two 2.0 GHz processors or the AMD 64 3800+ with one 2.4 GHz)

Philippe –
We’ve found a dramatic increase in real time performance when switching from dual Xeons (HP xw8200) to dual dual-core Opterons (HP xw9300) utilizing the Matrox Axio system with HDV sources.
As always, the faster the better … but those differences are small compared to the enhancements from the AMD dual-core architecture.

Multiprocessors although they can multitask they are more suited to parallel processing, where instructions,etc are divided up between processors to increase through-put, the problem with MP is it needs to be programed to work, and alot of programs that run on both single processors and multi-processors don’t have all tasks in the program programed for MP,
some programs don’t show any increase in through-put because they aren’t programed for it, with programs that have alot of tasks suited to MP can show different percentages of through-put increase depending on whether the task is memory intensive or processor intensive, a rule of thumb is an average of 50% increase, so if you had two 3200+(2ghz) processors you might see a system that looks like a 4800+ processor or more. -
Thank you for these explainations, is Premiere (and particularly the Pro 2.0 issue) programmed for multi processors?
-
Yes. It is, in fact, what we’re using.

Ask Adobe, yes. But actually no. You wont see much benefit with Premiere alone. However Axio functions are fully multithreaded.
Also it’s not parallel processing, it’s multi-threading which is a bit different and gives better results for content creation.

Adobe used to have lists of what functions were enhanced for multi for Premiere 6.x, older versions of AFX, Il, and Photoshop, I don’t think they have bothered to update this info to bring it in-line with their new products.

None of the filters are multithreaded in Premiere. However the media encoding is. I wish they would improve rendering speed, they seem to have been ignoring improving performance of Premiere when it comes to filters. If you have used Vegas (which I really hate) you will have noticed how fast and efficient it’s rendering is. I could never understand how one of the bottom end NLEs could have the best rendering engine – even better than Avid.

Look at 3D programs, Blender3D which is free, has one of the smallest installs, and packes a mighty mighty punch, and even renders quick on my Celeron Laptop! Try that with a high end 3D app?
Who can ever excplain why the major players don’t try and improve there render engines, it would be awesome if they would though! (PLEASE ADOBE!)
