i7-5820K vs i7-6700K

[hl2master]

The title says it. I'm planning to build a gaming/workstation Mini-ITX PC. I've been deciding between the 5820K and the 6700K, but I think more threads will really benefit me, although the 6700K should have slightly better single-threaded performance. And since X99 Mini-ITX boards are more expensive than Z170 Mini-ITX boards, I'm not sure which will be better. Just want to hear some opinions.

I'd go with the 6700k.Nothing else to say you already said it

If more threads would really benefit you, then 5820k. 

 

What is it that you're doing other than gaming (i.e. why would the extra threads help)?

6700k, much better performance in games and programs that use 8 threads or less.

In video editing and rendering and stuff like that it is extremely close to the 5820k.

Well honestly the gaming question part is irrelevant since they will both be more than enough for gaming, the question is just how intense is the workstation work, if it's going to greatly benefit from 2 more cores then go with the 5820k since it isn't much more money for 50% more cores

I think much is a bit of an exaggeration. And a 5820k is a decent bit ahead of a 6700k in rendering (even assuming something moderate like 4.2ghz on the 5820k and 4.5ghz on a 6700k).

Well this is a 6800k, which is better than a 5820k:

With the exception of Adobe, which unless I'm mistaken, doesn't scale very well after four cores, it does make a difference. So it depends on the specific applications being used -- and if it is a scaling issue, then at some point it will likely get resolved making the 6800k better. 

 

With the 6700k at 3.8ghz and the 5820k at 4.2ghz (to account for the 10% IPC difference), a 5820k should be about 50% faster (due to having 50% more threads). Then consider that a 6700k can probably hit 4.5ghz (about a 20% overclock from 3.8, which is underclocked, IK), and the 5820k should have roughly a 20-30% lead.

Video editing using Premiere and stuff

As of right now Premiere doesn't scale all that well after 4 cores, so a 6700k (at 4.5ghz) would only be about 10% slower than a 5820k (at 4.2ghz). But if Adobe ever gets off their asses and optimizes better for the extra threads, then a 5820k should be roughly 30% faster (assuming the above clockspeeds). 

 

So, I would say it really depends how long you plan on keeping the system for, how much you game vs. how much you render, and how important render times are to you. If you're going to upgrade within a few years, then get the 6700k. If you're going to hold out as long as possible before upgrading....then a 5820k should last a bit longer (and should gain a larger advantage in Premiere over a 6700k -- assuming Adobe gets their act together). If it doesn't affect you too badly if it takes 10% (presumably 30% in a couple/few years) longer to render something, then again, I would say go with the 6700k and save the $150~ price difference.
