5820K vs 6700K - Gaming Build

post #1 of 28
Thread Starter 
I'm working on a upgrade for a friend going from a AMD 1100T 6 core to a modern Intel system. The main purpose is gaming and web browsing. He isn't interested in the i5 series. He is set on a higher end system that will last him many years with only GPU upgrades for the foreseeable future.

So I started looking for parts for a new build in the low $1000 range not including GPU. I suggested going with a newer unlocked i7 then having me overclock it. Looking at the price of the 6700K blew my mind that a mainstream i7 quad is $400. What happened here? That price is outrageous so I started looking at other options.

Then I found the 5820k 6 core selling for $375. In gaming they are essentially the same performance. Overclocked they are usually within 2FPS difference, except when you get to multi threaded applications it will way outperform it. Then there comes the advantages of quad channel memory and having more PCI lanes. It looks like so much of a better investment than the 6700k in every aspect.

The price of Z170 and X99 motherboards both hover around $250 for a decent overclocking board with room for expansion.


TL;DR
Am I missing something here that should be pointed out? In gaming they are so close it doesn't matter and for anything multi threaded the 6 core will be better and is cheaper. Some input for one over the other would be greatly appreciated so we can make a final decision. Currently, I'm leaning toward the 5820k and am looking for any reason not to.

You basically said it yourself, snag him the 5820k! thumb.gif

What sold me was a quote I'm about to butcher from a different thread with the same sort of question,

"What the 6700k does better then the 5820k is marginal. but what the 5820k does better than the 6700k it does significantly"

This is the quote I tell everyone now about my choice to go with the 5820k...its a beast and a very nice cpu. My new rig is going along smooth.

Yeah the 5820k would be my choice too hands down, if they weren't so expensive here(not that 6700k isn't lol)

I think my xeon will be running for quite a while yet judging how each generation seems to get much more expensive for little performance gain lol.

Looks like no one can say anything in favor of a 6700K. I'll be going with the 5820K if he gives it the go-ahead to order parts.

Stating the obvious, but with the 6700K you're paying for the iGPU that you're not using in this situation. The 5820K is the easy winner in that scenario.

5820k. For something that will really last and with ample budget, moar cores is the way. Plus, the extra PCI-E lanes do really help on multiGPU setups.

5820k gets my vote as well. The 6700k does generally have very slightly better single core performance with the improvements of the Skylake architecture and generally slightly higher core clock potential, but the difference is small. As others said the 5820k gives you 2 more cores and all the other benefits of the x99 platform.

Also just a thought: Do you have a Microcenter nearby? The 5820k is $320 there, $300 if you buy the motherboard there too. I got a good deal on mine for $275 on eBay biggrin.gif

There is nothing wrong with the 6700K if u were to get that he would not have any complaints either since it is also a great cpu but the 5820k just makes more sense to me, especially since 6700k from what I had seen about a week ago were more expensive.

6700k have 10-25% better IPC in games and can utilize faster DDR4 ram better.5820k have more cores.For gaming 6700k is better.For work 5820k is better.
