4K Video Editing (Intel i7 4790k or 6700k)?

[Chris Topher iii]

I'm having a very hard decision as to which CPU I want to get. Normally, I usually edit 1080p footage on a supped out i5 (Don't judge me) lol. Everything that I needed was fairly taken care of, but now it's time for the 4K jump. Do you think I should grab an older 4790K/DDR3 or take the new approach of a 6700k/DDR4? I don't mind render speeds. I mainly would like smoother 1080 playback while editing the 4K XAVC footage. I mainly use Sony Vegas, & Adobe. I SUPER appreciate you guys for helping.

At same cost? The 6700K with DDR4.

I was saying go with the 6700K/DDR4

They are going to perform close enough to be identical in the real world, so in one sense it probably doesn't matter.

However, since the cost is likely to be very similar, I would go with the newer socket and memory type in the i7-6700 just so you have some hope for future upgrades.

One other option that most people overlook is the six core i7-5820k. It's only $50 or so more expensive than the i7-6700k and those 6 cores can help when rendering big video - especially if overclocked. The 6700 will have better single thread performance by a big margin though, with 4ghz vs 3.3ghz cores. Worth a look anyway.

In the few cases it is faster, it's only about 10% faster. In the cases it's slower however...

You also need a S2011-3 motherboard for it. And those are $100+ more expensive than a S1151 board.

Then on top of that you have the energy consumption; no-load energy use of a S2011-3 system is about double that of a S1151 system.

Then of course the i7-5820K is outdated and replaced by the i7-6800K that is faster, but Intel hiked the entry-price of the S2011-3 platform by making the 6800K more expensive than the 5820K.

Since OP is talking about video, it is more like 30% based on the benchmarks I'm seeing. And the 5820K has plenty of room for overclocks given that is is only 3.3Ghz stock.

Newegg has ASRock Extreme 4 X99 for $130 after rebate today. There are deals to be found. They are more expensive, though, yes.

Then on top of that you have the energy consumption; no-load energy use of a S2011-3 system is about double that of a S1151 system.

Sure, but both are very low. We are talking nickels vs dimes of energy.

I actually hadn't realized the 6800k was out as I haven't really looked for a while. It's 10% cheaper than the 5820K right now at newegg. Although it's a pretty marginal upgrade given that the entire <5% benchmark gain can be explained by the 0.1Ghz clock speed increase over the 5820k. They use the same motherboards and all, so that's a good option to consider, too. Really, though, 5820 vs 6800 would come down to whichever is cheaper given how close they are in performance.

For most people I would agree that the i7-6700k is best, but for a video or rendering workstation, the extra cores are great. Definitely worth a look. That's all I was saying.

What video card are you using? Since you are more interested in accelerated playback than rendering, focusing on upping your CUDA cores might be a better path to smooth playback than focusing on the CPU. Video editing in general likes more CPU cores and more CUDA cores.
