Old PC

64gb ddr3

4930k six core

780ti

I work on red epic raw 8k footage and I'll tell you using neat video or sharpening will make the footage go from 10 minute render time with no effects to 56 minute render time if I apply those effects.

What assists in faster render times the cpu, gpu or ram? I didn't notice a huge jump when I upgraded from 32 to 64.

Would it better to buy something like 4 top of the line AMD cards? Or 1 gtx 1080? Im seeing workstations just aren't viable and way too expensive for me to be worth it.

I was thinking new build would be

128gb ram ddr4

gtx 1080

6900k 8 core processor 4ghz overclocked

Will I see a massive increase in render times? Or just marginal?

Would it be better if it was 32 gb ddr4 ram four amd r9's?

Also I want to do a little bit of 3d simulations, so I'm guessing that's gpu intensive more so than cpu and ram... I'm unsure what to get... Any help is appreciate thanks guys.

With these new amd boards people are saying everything will be throttled like ram and the 1080... Should I steer clear of amd for this new build?

Also I saw on corridor digital they had 4 1080's and using octane rendered a super complex scene in mere seconds with octane, I wonder how well that'd translate to premiere or after fx.

amd am4 is going to be somewhat risky until others test it and see what its capable of. we may not see any good premiere testing for a few weeks, possibly longer. if it turns out to be good, then a $400-500 amd cpu may compete against a $1000 intel, saving you $500-600. you need to decide if you can wait for it to be released, or longer for it to be tested, and what you might do with the computer if it turns out poorly...

i think octane is 100% gpu renderer, so it doesn't get held back by the cpu. premiere and after effects are primarily cpu bound programs and won't work like octane does.

Of course I do not know anything about AMD yet but since Premiere and After Effects both are very CPU intensive I will give you some results that I have gotten with my PPBM testing

With my 8-core i7-5960X that I have the best CPU intensive test that PPBM gets with mine at 4.5 GHz and 64 GB of RAM and Premiere 11 (CC 2017) I get 250 seconds. I just recently have a PPBM submission with the new 10-core i7-5960X at 4.2 GHz on that same CPU intensive Premiere Pro timeline took only 205 seconds. A very significant improvement.

recent generations of intel cpu's have been about 2-5% faster per generation, so most of the performance gains over your 6 core would actually be from the 2 extra cores in a new 8 core cpu. the new 8 core might be around 30%+ faster of a cpu over the old 6 core you have.

faster render times are usually determined by the cpu, but if you are using any gpu fx or plugins, like neat video, faster gpu(s) can help speed up that part of the render processes. i believe neat video can use multiple video cards, but i'm not sure how many max.

current top of the line amd r9 video cards appear to be limited to 4gb of vram, so that won't be good. the alternative would be dual gtx 1070 8gb cards, or 1080's if budget allows. amd and nvidia will be releasing new cards soon, perhaps in a few weeks, so they might have better options or might help lower some prices of existing cards. if you are going with multiple video cards, now or in the future, you may want to consider the pcie slot spacing/layout on the motherboard you choose. having some spacing between video cards will help them get more air.

if you can salvage enough storage (ssd's/hdd's) from the old computer to carry into a new build you could get an i7-6900k, 64gb ram, dual gtx 1070's and everything else to build a new computer for right around $3k. you might be able to re-use the old computer case, cpu heatsink, and perhaps windows license to save money too. if the power supply is around 5+ years old, i would get a new one. intel also has the 10 core i7-6950X at around $1600 if you wanted to focus on cpu performance, but it may be out of budget.

Do you think the new risen amd processor would beat the 6950x in render performance? It'd save me a lot of money on the motherboard and CPU.

the 1700x is faster than the 6900k in multicore benchmark tests. as to if that correlates perfectly to premiere export numbers, I'd wait until march 3rd. but since its half price, its a no brainer from a budget perspective. and would amd instruction sets crash adobe? we won't know till next week.
