Skylake or Haswell-E

Now that Skylake is out, it uses DDR4, and we know how much both Z170 and X99 builds cost.

With that said, why would someone opt for Skylake over Haswell-E?

6700k is about $25-50 cheaper over the 5820k. Neither one comes with a CPU cooler.
Z170 boards are not much cheaper over X99 boards. Both platforms are in it for the same DDR4 cost.

Obviously you can easily skew this to make the Z170 platform the obvious bang for buck choice, but you can also make the X99 look like the better buy just as easily.

I usually invest in the new mainstream intel platform around its release. But this time, I think I'd rather spend the extra measly $100 at this point and just go 5820k.

Ok fine, some of you will say that you don't need more cores. You have to admit, right now, the Haswell-E is looking to be a better value over Z170, right?

Sure, you could also go with the i5 6600k, and honestly, that to me is Skylakes saving grace. Their 6700k cost of admission is too close to the 5820k.

What are your thoughts?

If you are just going to play games and nothing else get the cheapest platform.
But if you are going to use it for work or you just want something that can last 5 years or more go with X99.

IMO, even if you're just gaming, the small additional cost in the grand scheme of overall cost is justified by the platforms longevity. Ultimately saving money in the long run, right?

I bought X79 back in the day because i wanted the best and i am very surprised by how long it has lasted.
I am going to stick with X79 for at least another 6 months maybe more as there is no reason to upgrade, need a bigger HDD thats about what i need to upgrade.

So yes an X99 rig that can last you 5-6 years is cheaper in the long run then an Z170 rig that can last you maybe 2-3 years.

This is the decision I've been trying to make... the X99 series feels more like a transitory enthusiast platform to me when compared to X58 and X79, especially with Skylake-E coming so soon after, as new technologies develop and the market catches up.

Right now both Z107 and X99 aren't that appealing to me knowing that they'll both be antiquated in two years. Sure, performance wise they'll hold up, but that's why I'm still on P55... with PCIe 4 and other significant advancements around the corner it's getting hard to justify not to go with Z97 or similar and hold out.

I'd personally go x99.

I usually get the new platform, myself. Always look forward to it, in fact. This time around I'm not so sure.

After looking at some articles around the net, darned if I'm not starting to lean toward X99 instead of Z170. But it may get down to how much cash I can scrape up.

No doubt about it, X99 w/ 5820K. More cores/threads, lower freq DDR4 needed, mobo's have more features, more pci-e Lanes, similar gaming performance but better for rendering and physics games, soldered IHS, etc.

IMO, that's the worst one of the 3 available. Paying 2x the cost for 40 lanes vs. 28? Unless there's more I'm missing?

^ No that's pretty much it, with a minor excepetion where a 5930k on average might overclock extra 100MHz over 5820k, meaning slightly better binned mabye?

The Big deal is the 40 lanes, where 2 x cards will run at x16, still not sure if it makes that much difference at 4k res for example wtih 2 x high end gpu's as opposed to x8.

Pretty sure its been tested to death before that even I'm certain Titan X's can barely saturate a PCI-E 3.0 8x lane entirely.

http://www.techpowerup.com/reviews/NVIDIA/GTX_980_PCI-Express_Scaling/16.html

Results are over the map in range of 3.0 16x vs 8x, performance difference is +/- fractional %'s about I'd assume overall.

Conclusion;

For the majority of games, there is no significant performance difference between x16 3.0 and x8 3.0 (and x16 2.0, which offers the same bandwidth). The average difference is only 1%, which you'd never notice

After giving it some serious thought, I may just go 5820k. Skylake is a beast, but the price of admission isn't much less compared to X99. Hopefully people who are in the market for a new build consider things like this, especially since Skylake is here at the price it asks for.

The deal is that certain pci configurations will flat out not work on the 5820K.

Also M.2 support is kind of limited with the 5820K. With some motherboards, you can not run SLI and use an M.2 drive.

Some work station video cards are also kind of finicky about running with less lanes than they were intended for. Some people have noticed a substantial loss in performance on the adobe forums.

If all you want to do is build a baller gaming machine, then get the 5820K and just get a good motherboard that supports SLI and M.2 at the same time.

If you want to do some professional video editing, or you will be doing some type of rendering and you wanna have as many GPUs as possible....THENNNN get the 5930K.

Thanks Angle! I wish good info like this was more obvious. Just comparing the 5820k to the 5930k spec wise wouldn't tell this.

The latter has its place then.

Linus (linus tech tips on youtube) covered this pretty well in some of his haswell-E introduction videos.

If you want to learn more, I highly suggest you check them out just to make sure you are up to speed on some of the more technical aspects of x99.

Being six core, Haswell E will age better than the four core, simply because as time goes on, more applications are likely to be using more cores.

I will note that on the X58 platform, it is very common these days for people who have a 920 to upgrade to a six core, often a 32nm CPU, which is in many cases good enough to defer from upgrading to a modern platform.

The 6700k will be perhaps 15% faster in single threaded performance. The first ten percent from the fact that Skylake runs 10% faster clock for clock, but the next 5% because a four core will have more OC headroom than a six or eight core CPU.

There are a few games today like Battlefield 4, which are able to benefit from the extra cores. I suspect that the future will see more games benefit. The only other benefit for games perhaps is that one GPU will run at full x16 in dual GPU mode on the 5820k. It is a very small benefit though.

Then of course, outside of games, there are many applications like file compression, encoding, and so on that take advantage of the extra cores, along with the quad channel bandwidth of the memory.

I suppose that the benefits of Skylake, outside of the single thread performance are the stronger dual channel memory controller, which is a benefit that must be weighed against the quad channel memory controller on X99, and of course, the extensive PCH upgrades on the Z170 platform. The main benefit from the newer PCH I suppose is better PCIe SSD support.

In short, the X99 is more future proof for applications that can use the extra threads. You may also someday be able to upgrade to an 8 core when they are cheap, much like how X58 users upgrade to 6 core CPUs today.

I would recommend considering the X99A Krait edition, as it has a higher quality VRM than the SLI Plus.

5820K, best deal out there considering...
