I assume NDA and you can not say anything about it.

So anyone want to chime in:
Skylake vs Haswell-E/Broadwell-E
Spare the additional cores and extra PCI-E lanes is their really enough of driving force for one to consider Haswell-E/Broadwell-E over Skylake?
Please give me something to upgrade to Intel. Pretty please. This is getting sad.
I will not be upgrading for at least the next three years.
Blame no competition for many, many years.

Highly unlikely. I'd be surprised if they break 5 ghz.
I'm perfectly fine with my 3770k.
Dear God, this. I hope the rumors of an AMD/Samsung buyout are true. AMD gets money to pull it's head out of it's ass in the CPU segment and Samsung gets rights to AMD GPU tech for integration into ARM devices.
Overall it'd be a nice shot in the arm for competition.
Correct.
Unless 14nm sucks at overclocking, I think the 6960X is going to be a big enough e-peen upgrade over a 5960X to justify it.
Edit: * subject to change since this crap is still a long way off so who knows what sort of gimping or other market decisions happen.
What I'm saying is that people who pay for a high core count Xeon chip should be able to use the huge amount of headroom that's present in these chips. As I said above, the E5-2699 V3 when run at 105MHz bus speed (2940MHz) run at 0.9V and run quite cool. I know such a chip wouldn't match a chip with a lower core count in pure clock speed, but a modest clock speed between 3.5GHz and 4.0GHz with a slight voltage increase and should be easily obtainable under water without risking damage or instability.
makes no sense to me to have broadwell sku's and skylake sku's selling at the same time.
Here's hoping Skylake-K comes out before the end of the year (and is significantly faster than Haswell or at least overclocks better). To be brutally honest I don't think any of us care about Broadwell. The most strenuous things I do with my computer tend to be gaming so the high-end consumer chips are what I normally buy (-E series being slower on a per core basis and all).
Skylake is the only hope enthusiasts have left. It's entirely possible that Sandy Bridge will go down in history as the last great architectural improvement on silicon.
The picture shows 95W K, 65W and 35W parts released at the beginning of Q2. I expect anyone that knows if this is accurate is under a NDA and can not legally confirm or deny this.
You're reading it wrong. The slides indicate production starts at the beginning of Q3. Probably means actual sales and whatnot are a month or two later.
12 cores over-clocked over 5ghz would motivate me to upgrade.... till then throw the money at the GPU,..
The largest die will be for Broadwell-EX and may be up to 24 cores (somewhere between 18 and 24). A nice chip with great potential, but again, they will be completely hard locked. Given that the current E5-2699 V3 (when overclocked by the measly 4 MHz that you can do with the locked BCLK straps) runs with a Vcore of 0.900V at nearly 3.0GHz, the incredible clock speed potential of these large die CPUs is obvious.
Part of the reason that the high core count chips have such a low vcore is that they have to. There just isn't any other way to manage the heat from those dies.
You'll never be able to clock the high core-count chips as high as the 4, 6, or even 8 core parts that we can overclock. A 24-core chip would have, obviously, 3 times the heat dissipation of an 8-core chip at the same vcore/clock speed, and a whopping 6 times as much as an equivalent 4-core chip. Even with the best water cooling setups, you're still going to run up against issues of conducting that heat out of the dies.
I don't really get where you say there is large overclock headroom. No one really knows and it goes against well known and established chip fabrication experiences. Quite frankly any time you add more cores, the likelihood of one core being defective at a high clock rate exponentially increases per additional core.

There's also more localized heat transfer problems. With huge die, some cores are going to be surrounded on all sides by other cores. What we see on 4 core die with the middle cores being hotter than the outer cores...same thing scaled up.
Random tangent, but if we all banded together and ordered a few million bucks worth of chips, Intel could/would make a custom brew of -EX. 300W TDP, 18 cores, 4 Ghz. Start saving pennies now
To me the only reason to broadwell-k will be in the same socket as haswell and same ddr3 while skylake-k will be in a new socket and require ddr4 other than that people can wait a month or so..
More cores and pci lanes is pretty much the main attraction for -E. There's also SATA ports if for some reason you need 10 instead of 6. Even Skylake won't support 10.
The really crappy thing is that even with the extra 6 Gbps ports on X99, you have to deal with the fact that the DMI 2.0 bus will become a bottleneck in VERY short order and largely nullify the advantage of more 6 Gbps ports. One more 6Gbps SSD can be added to a two drive RAID 0 configuration that existed under X79, but that's about it...three SSDs will saturate the 2GB/s DMI 2.0 bus.
NVMe drives are an option to overcome this bottleneck...
Just chiming in here to say thanks lutjens, your posts are intelligent and useful. Specifics, facts, and rational reasoning?? We're glad to have you here.
Guess what my next upgrade is going to be in March?
I'm just waiting for a little more finality and polish on Windows 10 before making the leap (as I want bootability and detest Windows 8.1). I may just end up waiting for RTM, although the lasted Technical Preview looks pretty good.
