Z170 vs X99

[CyberDevil]

I already know that the budget friendly Intel Core i7-5820K performs better than the Intel Core i7-6700K and in turn the Core i7-6700K is ahead of the Core i7-4790K in benchmarks. But the question is, which system would you buy? The Z170 boards are way cheaper than than the X99 boards. Wikipedia states that the launch price of the Core i7-6700 would be $389.99 (if I remember that right), so the excepted price of the over 6700K should be around $419.99. The cheapest Z170 board would be around$149.99 with dual channel DDR4 with tendencies to over clock the RAM up to 3400MHz.
What to expect when you're expecting?

Plus the i7 6700K has 16 PCIE3 lanes compared to the 28 lanes on the i7-5820K.
And the Intel HD 5000 integrated graphics provides HDMI2 which can scale to a resolution of 4K.

What will this be used for? I have seen gaming benchmarks where the 4790k is equal to the 5820 and in some cases the 4790k did a tiny bit better. Its not something I have looked into in any great detail but I know the 5820 is better for things like video editing and programming.

It will used for gaming and programming.

Actually, it doesn't..... in some respects (i.e. rendering) it does but overall for gaming + other rig, 6700k > 4790k > 5820k. Again, depends on the other but even in many aspects of video editing, the 4790k outperforms the 5820k. When the 5820k does lead, it's by a small margin and a) this often disappears as the silicon lottery seems to favor the 4790k / 6700k a lil more than the 5820k and b) the cost savings between Z97 / Z170 and the X99 oft pays for a GFX card upgrade.

6700k vs 5820k - Stock (Note, the 6700k has a bit more OC Headroom

The only time we recommend X99 is when a) you are using 3 or more GFX cards and b) you have some specialized app that uses the more cores available. Of course "programming" is a broad term and your decision must be based on three things:

1. How well does the particular software used perform on each platform ?

2. What is the relative ratio of gaming to programming ?

3. What is the relative impact ? By that I mean, say for an office app .... I don't much care how well an office app performs running a script of common tasks as in the office, we don't run scripts and the performance of the app is bottlenecked by the user not the app or the machine it's running on.

Twice as fast means something when it's 20 versus 10 seconds but not when it is 0.3 vs 0.6 seconds.

The i7-5820K is not in any way shape or form a "budget friendly" processor. It might be in that it's a better value than the i7-5930K which is the exact same CPU with a higher stock clock, but to call it a "budget friendly" processor is underestimating its' value. The i7-6700K is not $419, any store that charges you that much is ripping you off. It should be no higher than $359 at the moment. As to how it performs in real world applications that entirely depends on what you are going to do with it. Gaming? No. The only advantage you gain for gaming is if you want to use more than dual SLI. That's about it. The X99 CPUs mainly function as high end workstation processors - they're not geared toward the average user or gamer.

The price premium for the 5830k has little to do with the clock speed; it's all about PCI lanes. X99 is the way to go for > 2 GFX cards whereas other solutions require a somewhat kludgy PLX chip.

5820k has 28 lanes (3 GFX cards + 4 lanes left over for M.2 whatever)
5930k has 40 lanes (4 GFX cards + 8 lanes left over for M.2 whatever)

As for 4790k vs 6700k, the difference here lies in additional PCI lanes for M.2 whatever
https://www.pugetsystems.com/labs/articles/Z170-vs-Z97-What-is-the-Difference-636/

Graphics Support:
4790k supports 1x16 or 2x8 or 1x8+2x4
6700k supports 1x16 or 2x8 or 1x8+2x4

Additional PCI-E lanes:
4790k supports 8x PCI-E 2.0
6700k supports 20x PCI-E 3.0

Yeah that's kind of what I was trying to say earlier - the only real reason to go with X99 for gaming is the extra PCI lanes if you want a triple 4K monitor setup or Oculus. That's the only real benefit there. Otherwise there's nothing that is really gained by going with X99 over Z170.

It really surprises me that peeps come and ask me to build a CAD system w/ X99 as there is a widespread mindset that ya can't do CAD w/o a Z99 & Quadro build. AutoCAD 2D and 3D actually perform better on Z97 / Z170 / GTX builds. Now when ya get to Maya, Solid Works and such where rendering is the thing, THEN X99 and Quadro rock. Such is the nature of the internet. An informative post oft gets misinterpreted and, like the old telephone game kids played 50 years ago.... what comes out at the end oft bears very little resemblance to the original. There's no absolutes, sometimes one will excel, sometimes the other. Put that one up there with ....

1. Anything over 1.5 volt RAM will void your Intel Warranty - this persist despite the fact that over half the RAM kits on Intel's certified compatibility list is > 1.5 volts

2. Faster RAM has no impact on gaming performance - this came about as reviewers compared $120 DDR3-1600 and $250 DDR3-2400 when DDR3 first came out and said it was not "worth" the increase in price. When the price spread dropped to < $20, this was still being repeated but clearly the "value" equation had changed. Wasn't helped by reviewers who tested 3 games and called it a day. System performance will be curtailed by whatever component is the bottleneck and sometimes, maybe not very often (i.e STALKER series, F1), that is going to be the RAM.

3. 2 Pound air coolers will damage your MoBo - Certainly if you let the FedEx ground gorillas handle you PS when shipping, expect it nit to survive. But clamping those CLCs / Air coolers / water blocks down with 70 pounds of clamping force (recommended TIM pressure) has much more impact on the MoBo than a 2 pound cooler does. I have done 3 rebuilds to date where a Hyper 212 was over tightened by the user and damaged MoBo....one was saved just by loosening clamping mechanism.

6700k is fine for now even you can save money and buy 4790k because ddr4 doesn't help in games but the think people say 4790k and 6700k performs better then 5820k but the thing is now a days games require quad core so if you wan't to future proof you pc then get the 5820k

 

[popatim]

If you're just gaming either one is a valid build still since Skylake doesnt game much better than Haswell. Even SB is still in the running.
http://www.anandtech.com/show/9483/intel-skylake-review-6700k-6600k-ddr4-ddr3-ipc-6th-generation/15

Since I do video editing occasionally I went for a 5820 build myself once the (quality) skylake reviews started hitting the net. No loss in gaming performance and only $20 more in build cost.

Except that isn't going to make a PC future proof. Nothing will. There's very few games that take advantage of six cores. And even fewer that take advantage of six cores and hyper threading.

Z170 is already a good combo for 4K with a GTX 980 Ti and an i7-6700K. However, in order to use Ultra settings, anti-aliasing must be left off. Thus,frame rate at Ultra and 4K may ot satisfy serious FPS gamers. Moreover, if you want 2 GTX 980 Ti and SLI, the CPU would bottleneck the cards waste of mone. So, for 4K, go for X99
In the other hand, GTX 980 Ti and i7-6700K with Z170 can DESTROY all those games out there at 2K, even with PhysX High, Ultra settings, anti-aliasing 16x with LOTS OF FRAMES PER SECOND. So, for 2K, Z170 is perfect, X99 is overkill

I have been reading for a few days now and I am still not sure which would be best for my situation, I am coming from using a X58/I7-980X Hex core rig, O/C to 4.0G with 3 GTX680 4G video cards in triple SLI and 12Gs of DDR3 1600 RAM! I only use use a single 32" 2556X1440 monitor on the Display port and have no intention of going multiple monitor any time soon Not sure about 4K yet either but I fully intend on having at least dual SLI with two Gigabyte GTX980TI Xtreme gaming 6G video cards for some forward compatibility/future proofing, with that being said, is the bandwidth of the 2 full X16 PCIE lanes and extra cores on the X99/5960X combo, that much better than the X8 PCIE bandwidth you get from the Z170/6700K when you use two cards, would anyone know the precentage's and/or any real world "performace" differences especially when/if O/C is involved, I got "learned" after buying and using my last system "more" is not always better..(Wry Look)..and I am not looking for bragging rights, just a system that will be able to game for several years at least hopefully, thank you for your time and attention!!!

Mage_Warrior,

To answer your question. No, it doesn't when you are talking about PCIE v.3 as it is twice as fast as v.2. and you are using 3 cards or less.

OP, x99 all the way.
