Extremely high end video editing rig: more CPU or GPU?

[evilmeister13]

I edit my videos all in 4k 60fps and they usually tend to come out at least an hour long. With my current setup, (Core i7 5820k paired with 8gb of ram and a gtx 1080) it takes like 5 minutes to edit even 15 seconds worth of video, my longer videos have left my computer unusable to me for days at a time and once or twice crashed out and I had to start all over. I'm looking to get a serious hardware upgrade to speed up my process immensely, but I'm just not quite sure what area of the PC I need to focus on. Assuming Price isnt a barrier, would I be better off getting an 8 core chip(like a 2700x) and a baller gpu like vega frontier edition, or would I see better performance getting a monstrously threaded cpu(like a 1600x or the upcoming 32 core threadripper)? Any ideas on how much RAM I would need to be looking at are welcome as well.

You'll get better performance from having more cores and threads than a GPU. Especially in Premiere. Though if you have Premiere, you should be using Intel iGPU hardware acceleration.

 Personally I use sony vegas 14, and an i7 5820k doesn't have an igpu, nor do any of the builds I'm looking at making. Besides, I would think that almost any recent dedicated gpu would be much faster than any of Intel's integrated offerings, unless you have any comparisons I could look at?

You would think that, but you would be wrong. The iGPU blows dedicated cards out of the water thanks to Intel Quicksync

If you're using Vegas probably just stick to Ryzen, but what's your Budget/Country? I like Vegas more than premiere simply because you're not paying a sub fee for seemingly unstable software.

This is true, but from what I hear quicksync provides speed over quality. If you need every spec of quality in a video, quicksync isn't the greatest choice.

I don't really have a set budget at the moment, I'm thinking somewhere in the $5000-$7000 range is probably where I'm gonna land since I'm most likely going to be getting the 32 core threadripper and multiple TB of ssd storage

Yeah i do need quality over speed for sure, just looking to figure out how to speed things up with new hardware.

You don't need to get more than a 16 core because Vegas 14 is limited to 16 threads anyways. So you'll just want to set it in CPU affinity to use one thread per core, or just disable SMT before rendering to make it automatic. Or use like ThreadLasso so it remembers your affinity.

Probably don't need that much NVME storage either, if you don't have a NAS already build one of those

 

As for the GPUs anything with Vega 56 or 1070ti should be fine. Probably looking at like $2K max for the machine.

Your current system needs more memory. A Lot more memory. A 4x8GB kit would be good.

I do 4k editing in Vegas with only 16GBs of RAM, doesn't even fill it up all the way, but it for sure uses more than 8GBS
