32 Gigs of RAM in Mac Pro — After Effects Performance Gain?
I’m going kinda batty deciphering all of the Memory posts and information about utilizing RAM in After Effects so I’m posting this question and hoping it’s not too redundant.
I have 16 Gigs of RAM in my 2006 8 Core and prices look pretty good to me to pull the trigger on putting 32 Gigs into my machine. Couldn’t hurt, right?
But the burning question is will I gain any significant performance with AE (or Cinema 4d for that matter)?
Ram Preview speed improvement?
Render Frames Simultaneously improvement?If there’s some succint answers to the Pros of 32 Gigs, I’d love to hear them. If it’s only a speed “bump” then why bother, eh?
Much thanks, and I have the link to the adobe help files about memory usage, just hoping someone has the short answer or has 32 running in their 8 core.
cheers.

Nearly 4GB per process is the limit on 64-bit Windows. ~3.5 GB per process is the limit on Mac OS (though the foreground application gets a little less because of the Mac OS UI libraries). Because these numbers are per-process, and because a 64-bit operating system can see a lot of RAM, you can make use of around 30GB of RAM in an 8-core computer.
Yes, some compositions will render more quickly with 32GB of RAM in the machine than 16GB. Some. The usual caveats apply about not every render being bound by RAM. (Sometimes the source disk is the bottleneck; sometimes the output disk is the bottleneck; sometimes the CPU is the bottleneck; et cetera.)

Thanks much Todd. Seems like a worthwhile investment. As I said, couldn’t hurt, eh?

I thought Rosetta imposed a memory ceiling of around 1.5GB?

Be interested to see if 32GB works…

How is Rosetta relevant here? That’s just for running software in an emulation environment (running old PowerPC code on an Intel-based Mac).

@Todd and All
32 GIGS locked and loaded. CS4 products in general load MUCH faster. AE moving along smoothly. Will report any benchmarks later.
Much thanks to Todd and all for input.
No Rosetta here kids, all INTEL.
