Hi everyone.
There's a few old topics on this that I can find but no recent ones with any feedback from Adobe that I can find - if there is, just point me in their direction!
I'm looking to build a new rig with a budget of £4000 (ish) but having difficulty deciding whether I'd benefit from the extra cores (20 vs 8) a Dual Xeon setup would provide, vs a high powdered i7 build. Something like...
Dual Xeon E5-2630 v4 (£1230, 20 cores total) vs Core i7 6900K (£950, 8 cores total)
The primary objective of a new build is to speed up render times in After Effects. I do 3D work as well so a boost in rendering speed in that will be really useful too, but I primarily use After Effects for my work.
Now, I know in the past (CC2014 and prior) After Effects could only really make use of all those lovely cores if there was enough memory for each one, so buying loads of RAM used to make sense. If this was CC2014, for a 20 core system (40 if you count hyper-threading), I'd need at least 128Gb RAM (3Gb/core, or preferably 256Gb to allow 6Gb/core) to make it really worthwhile for speeding up renders in After Effects.
BUT, since CC2015, the rendering engine has changed a lot and I can't find any solid information on whether each core needs so much RAM anymore, or whether After Effects actually benefits from loads of cores that the Xeon's would provide in abundance, or the relative higher clock-speeds per core that the 6900K blasts out.
I do know (at least I think I do!) the dual Xeon workstation will be significantly faster for 3D rendering in C4D (and Max, and Houdini etc.) than an i7 6900K will be, but that's not my main concern, especially as I intend to stick at least two nVidia GTX cards in there (1070's or 1080's) as I use Octane to render when I can anyway, which is a GPU based render and once it's optimised for CUDA8, two GTX 1080's should provide a pretty decent/fast 3D rendering solution for my needs.
Any advice folks? Anyone happen to have used both those CPU options, or are able to provide benchmarks for similar setups?
I'm happy to put together a few AE project files for someone to benchmark if you're up for it!?
