Question

Wheres the bottleneck?

Hey gang, I'm run an Intel quad core 3770, 32gb of ddr3 1600mhz, and a tired ati radeon HD 7870.

My question is; I was looking to upgrade my GPU, but is dropping moneies on a new card gonna even matter with what I assume to be a CPU bottle neck.

I'm looking at the ATI radeon RX 580 8gb or the Nvidia 1660 6gb. but are either/both of these going to be over kill for my CPU and not really give me any performance gains.

Currently my GPU is only utilized like 3-6% in task manager. I'd hate to upgrade to still see GPU barely being used.

    We can't know. It's easy to assume all sorts of bottlenecks with AE, but the specifics are all in the details of each individual project and what functions, features and effects are used in which combinations. Some of that will work just fine with GPU acceleration, but more often than not combinations of things will disable GPU usage due to how AE's rendering pipeline works. the only thing that's for sure is that in general you don't solve AE performance limitations with hardware, no matter whether it's GPU or CPU. Beefing up a CPU can be just as useless as shelling out tons of money for a GPU that AE won't use. It's all about optimizing workflows and structuring projects efficiently if possible. So, yes, just replacing the GPU will likely do zilch. Anything else would require much more specific info on what you actually do.

    I agree with Mylenium.  Render bottlenecks are as much to do with project planning and structure as they are to do with GPU hardware.

    What plugins are you using in your project?  Are those plugins GPU accelerated?  Are you using non-GPU plugins on the same layers?

    If your projects are CPU reliant, rather than GPU reliant, you may be far better off spending money on a multithreaded render tool like RenderGarden.

    Or by buying a beefier CPU instead.

    If you can provide specifics about your project type and workflow we may be able to offer more concrete advice.

    Im mostly animating 3d text messages (standard Arial basic white text) and masking it out of certain areas. The only effects I'm using so far are drop shadow, camera blur, CC slant, and point motion tracking (3d camera track doesn't work for some reason)

    There is a 3d text elipsis scene coming up where I'll probably be using big 3d elements to and have them as large somewhat interactive dealies ( this part is just outside of my skill set, and I've yet to tutorialize myself)

    The project is 1080 and on playback (and playback freezes) my gpu will get up to 17% utilization
