i7 vs i5 for video editing?

fishbowlbob · Jul 29, 2016

Howdy!
I've asked this question around, but haven't found a really good answer, so here it is, once and for all:
Is it worth the extra 100+ dollars to get an i7 6700k over the i5 6600k for editing 1080p video in programs such as Premiere Pro and Davinci Resolve? I'm really conflicted here, and I need to know soon. :/
Is the i5 6600k usable for video editing for say the next three or four years, or is it worth it to invest in the i7 6700k?
I would really appreciate any answers, I'm flip-flopping back and forth between these two CPUs.
Thanks so much,
Jake

OP said nothing about gaming.

Hyperthreading is worth 30-40% extra performance, generally. A 6700K costs around 40% more than a 6600K. Both will be equally capable of actually doing the editing, the 6700K will just do it 40% faster. If you look at total system costs, an i7 is generally more like 10-15% more expensive than an i5.

Hard to say, I'm not aware of current skylake premier pro comparative benchmarks. When it came to devil's canyon there was only a 6% improvement in premiere pro due to hyper threading. There was an 8.6% speed improvement between the slower 4790 and faster i7 4790k (400mhz faster out of the box).

Hyper threading gives an improvement in premiere pro for sure, but 40% faster? I don't think I'm sold on that. The i7 6700k was almost tied with the i7 4790k in all but mpeg2 software. There was only a 7% improvement there from haswell to skylake, not the often touted 10%+ due to generational ipc differences.

If it were in fact 40% faster then the cost/performance ratio would be pretty even but I don't think that's the case. Faster yes, 45% more money yes, 30-40% faster? Not so much. The current price difference in usd according to pcpartpicker is 44% between the 6600k and 6700k.

Much of the performance may depend on the gpu as well, not just cpu alone.

If you're heavily into video editing as your primary goal and you have the budget for a 6700k, it may be worth looking at x99 and a 5820k 6 core 12 thread i7. The price won't be a whole lot different and you'll have the benefit of hyperthreading but more importantly 2 more physical cores.

40% more throughput in perfectly threaded scenarios, I should say, but for instance it's rarely the case that an i7 is twice as fast as an i3 in anything, despite being almost exactly twice the CPU.

SkyArc :

We'll put it this way. I game more than I edit, but the build is more for editing than gaming. I would like something that would last me a few years, and I have a preferred budget of around 800 dollars. I already have the rest of the system picked out, I just need to know if it is worth the extra hundred or so dollars to get the i7. I can skimp on the GPU if necessary to fit the i7 in the budget if it's worth it.
I've looked into Xeon, I just don't know if that's what I want to go with. I need to make a decision pretty quickly.
Thanks for all of the input,
Jake

A lot of people who do exiting professionally will opt for one of the bigger i7's, even. The 5820K isn't much more than a 6700K and has 50% more cores. If 2011v3 motherboards weren't so much more expensive, I'd probably argue strongly for the value of that platform.

Thanks for your input! Due to budget reasons I decided to go with the i5, I think it will be good enough for me for a while.
Thanks!
