From what Iâ€™ve read, and from my own tests, I believe the following to be true. Would anyone care to confirm, amend, or refute these statements?
Max/MSP/Jitter only takes advantage of multi-threading if you use the poly~ object.
Given all of this, for Jitter-intensive projects, it’s better to go for a higher speed dual core (e.g. Intel Core i5 3.46 GHz) than a quad core machine with a lower clock rate (e.g., i7 3.06 GHz).
Thanks for any comments, corrections, clarifications, or suggestions!

i was under the impression that jitter objects are optimised for multi-core threading… but i may be wrong< ?>
video cards do make a difference as the intel GMA ones share RAM with motherboard, so it would be best to have a fully independent graphics card (preferably with lots of RAM) to get a better FPS rate.
i know its still on the horizon, but open CL may be beneficial in the not too distant future.

yes, poly~ only multithreads audio, and only when you tell it to.
two instances of max (either by duplicating the max app or the max runtime, or creating separate standalone apps) will run on whatever cores the OS tells them to, ie, they can run on separate cores.
any jitter work where graphical performance is one of your primary concerns, should utilize opengl, and therefore would benefit from a fast GPU.
max is 32 bit, and i believe that means it can utilize 2GB or RAM
it depends on the application. if you are able to split up processing tasks (eg, if you have a lot of audio processing and jitter processing), then 4 cores could very well be utilized fully. if you are just using a single app to perform jitter CPU calculations, then probably a faster dual-core would be better.
if you haven’t already, take a look at the event priority article:

Great article, thanks Rob for the pointer and thanks to jkc for the clear explanations.
Wondering if there are more recent developments along these lines? Would be nice to know if there have been significant changes with how the threading etc. operates.

Hey Rob, thanks for the article.
