Extreme rendering math
on Sep 25, 2016 at 12:42:46 pm

Right now I have;
Processor: Intel(R) Core(TM) i7 CPU 950 @ 3.07GHz
Video Card: AMD Radeon R9 200 Series
RAM: 24 GB

and I have a AE project that takes about an hour to render.
I was wondering if my math below is correct or if I am missing something.

24Gb RAM = 60 minute render
so If I got 1TB of ram my render time would equal:

1000/24=41.6
60/41.6= 1.44 minutes


Is that really possible? I know it would be expensive, but can I expect that kind of performance from AE?
If I ended up getting 2 xeon CPUs would that change anything?

[Adam Hoek] "Is that really possible?"

If, for some reason, you'd get a system that would support that amount of RAM then you'd probably have some absolutely insane hyperthreaded 20+ core processors too. It would be faster, yes.

It really doesn't work that way.

this is my concern. what about it doesn't really work that way?
I feel like im missing something pretty obvious, but cant put my finger on it.

Not all frames have the same render time. You might have some frames that render in a second and then you might have frames that render for 20 seconds. The render will be faster if you can split it to multiple processors (this doesn't work in CC 2015 yet) but there's no formula for counting exact render times for a comp that's running on a certain hardware setup.

Also RAM isn't the only factor in rendering.
