It depends on your application. DDR3 does have lower latency, but DDR4 has double the bandwidth. http://www.corsair.com/en/blog/2014/september/ddr3_vs_ddr4_synthetic

Will Skylake be a big leap forward?

That's synthetic benchmarks which basically means it's effectively useless.
Back in the day when we used both a South Bridge and Northbridge and the MC was on the Northbridge latency would show a bit of a performance boost.
Now with the MC on the CPU its not much of a factor.

Memory will be terrible at beginnig like it was when first ddr 3 vs ddr 2. But as time goes by timing will improve with binning. There's not a ddr2 set I would trade for my ddr 3 and I had some of the best stuff. Not that it really matters anymore unless your in competition

DDR3-2133 C11 vs DDR4-2133 14-14-14 350 2T in real-world scenarios on a 5960X from Anandtech.
Pretty much a wash.
It's unfortunate that the Z170 is so underwhelming platform-wise. At this point, DDR4 isn't such a big deal anymore.

DDR has kind of been irrelevant since DDR2, the last big upgrade that was noticeable memory wise other than adding raw capacity.
Couldn't tell you the difference between DDR2 > DDR3, but I sure as hell remember going from DDR1 > DDR2 or SDRAM > DDR1.
At this point DDR4+ is strictly to impress enterprise/server customers. With stacked die's, speed increases, and less power it only makes sense.

Update for today: Skylake benchmarks. Take this with a grain of salt though as they are not official benchmarks, nor from a site I frequent.
This is the same clickbait link that was posted earlier in the thread, nothing new to see here.

The real reason for this is everyone compares the last version of the previous memory standard to the first version of the next memory standard.
DDR
1,600MB/s to 3,200MB/s
100mhz to 200mhz
DDR2
3,200MB/s to 8,500MB/s
200mhz to 533mhz
DDR3
6,400MB/s to 24,800MB/s
400mhz to 1550mhz
DDR4
17,066MB/s to ....(27,200MB/s currently)
1066mhz to ....(1700mhz currently)
So you can see each memory standard basically picks up where the last one ends, but is designed for more head room, eventually the new standard ends up being far faster than the previous because of the architectural changes. But switching from the most mature DDR3 tech to the earliest DDR4 tech isn't going to be a huge win.
Well, imho it's because.. if you believe this.. i have an eiffeltower to sell you..
Due to a lack of information/benchmarks using DX12, I'll just quote a military giant from WWII: I know nothing.
I'm with you!

I'd like to see a company actually release a ddr3 skylake motherboard. Latest rumors/discussion point towards it probably not happening.
I bet the price gouging on release will be super high, probably more than what it would cost for a 5820 setup.
If you are forced to use ddr4 [and pay the premium], why choose skylake over a 5820? Only reason I can think of is if the average overclock window is high.

Skylake overclocking under Prime95 is looking up.
Yes. I am on Sandy Bridge too. i3770k @ 4.4GHz. I just started having trouble with my motherboard (I think it is, either that or 980Ti, not sure). At any rate, I think it's time.
There are bound to be Skylake SLI motherboards that take both DDR3/DDR4, correct? I'd like to be able to edge into DDR4. DDR4 is bound to be expensive when it's first available.

DDR4 has already been availabe for awhile now. The price of DDR4 has actually already dropped signficantly. While it is still more expensive than DDR3L as DDR3 prices have also dropped in the last half year the premium is not that high anymore.

I hate to be that guy..but a 3770k is a Ivy Bridge.
Seriously though - I feel now is time to flip my 3770k / Z77 combo for a newer platform.
To me personally, the value window for the 6/7 series platforms is getting close to that point where you won't realistically be able to flip your 6/7 series board/cpu for the amount necessary to cover the cost of a newer platform refresh to a 9 series (or maybe even 8).

I am hearing rumblings of 4.7 to 4.9 under heavy loads at not crazy voltages. Managing heat loads is looking good.
Y'all still hanging on to the 2500/25600K will likely find that it is time to make the jump finally. And honestly, the only reason I am not still on my 2600K is to keep up with technology since I have to understand and write about it and using it personally makes that a lot easier, this would probably be the series I upgraded with.

Do we have a basic consolidated list of architectural changes we're lookin at over the 2600k line? I know there's some solid iterative gains for Skylake in IPC and a few other areas, but haven't really gotten too many tangible details.

What really matters is that we have seen basically 7 to 10% IPC increase every architecture change since then (Sandy Bridge - Ivy Bridge - Haswell - Skylake). So that is a pretty good add up since 2500/2600 days. Good power saving / temp drops on these 14nm chips too.

Skylake is two generations of IPC improvement over the 5820k.

You don't really think you need a Haswell E for gaming. Skylake will run a lot cooler, likely give you better stable overclocks, and ~10% better IPC. If I was building now, I would go Skylake unless you have specific needs for extra PCIe lanes or other benefits for connectivity.
When I put up a post in the general hardware section about building a new gaming PC I originally was going to use an Intel Core i7-5960X since I saw it on many review sites but was told to go with the 5820K to save money.
What do you suggest? I am not a CPU expert at all.
BTW Here is my proposed build.

I don't say this often, but you might wait. You might be more impressed with Skylake than you think, and honestly, for gaming, even with SLI, the "limited" PCIe lanes are not going to be holding those cards back on a good motherboard.

Skylake-K for single gpu, a X99 is still a major advantage for SLI/multigpu.
https://m.youtube.com/watch?v=ZABt8bHgDHo
At 4k with newer games and 980ti SLI you are looking at a 20-30% gap in performance between quad core haswell and hex core haswell at same frequencies. Skylake at 7-10% improvement won't close that gap in multigpu gaming so advanatage still goes to 5820k.

I have an i7 920. This will be the time I upgrade.
Its only because I feel like I need to, but this thing is a beast on its own. Though it will mean I have two of them mwhahahha!
