Well isn't this thread the gift that keeps giving.......
So if someone can explain this to me :
Why is 1151 unlikely to be refreshed to have 6 cores like haswell-e? I'd like to buy into the 6600k at 4c/8t and be able to upgrade cpu at some point to have more lanes IF I need to add it for dual GPU gfx cards or if i have to bite the bullet and buy into dual cards.
Mike id be glad to explain to you why you wont see a six core processor for socket 1151. Socket 1151 will support two generations of processors Skylake and Kaby Lake. Cannonlake the chip due after Kabylake will require a whole new chipset currently called Union Point '200' series
see here:
https://en.wikipedia.org/wiki/Cannonlake
'Cannonlake will be used in conjunction with Intel 200 Series chipsets, also known as Union Point. The platform as a whole will be named Union Bay'
Now in the past with an intel socket you generally had two generations of compatible CPU's. Normally starting with a new CPU design based on the same manufacturing node as the previous gen chip (i.e. Skylake is a new CPU design on a 14nm process which is the same as the previous gen Broadwell) you would then get a die shrink of the same CPU design ( i.e. Broadwell is a 14nm shrink of Haswell).
This is referred to as intel's 'tick/tock' release schedule.
This started to falter with the release of Devils Canyon which was neither a die shrink or a CPU redesign. It was a 'tweak' of an existing design to improve it a bit (you will notice that Devils Canyon remains a '4000' series CPU the same as Haswell consumer CPU's to reflect this i.e. 4770k/ 4790K)
In this fashion in looks strongly like Kabylake will be to Skylake what Devils Canyon is to Haswell - a 'tweak' Intel will not be redesigning the whole CPU and will not be making it on a smaller manufacturing process. The early indications are that most of the effort will go towards improving the iGPU with the addition of an 'L4' cache (ala Broadwell) on the CPU which will mainly help you if you are using the onboard graphics. The only other known difference over Skylake is native USB 3.1

So what does this all mean?
Well Intel designed Skylake to work in conjunction with the Z170 chipset and Kabylake is just a tweaked Skylake. Consumer Skylake is a four core CPU. That's it there are no deactivated unused cores in there Intel have designed it from the ground up as a four core CPU. To make a six core CPU for socket 1151 (assuming its even possible) Intel would need to completely redesign the CPU from the pretty much the ground up as the die arrangement would radically change to accommodate two extra cores. That before we get to whether it even possible.......
X99 has 2011 pins in a standard socket to Skylakes' 1151 for multiple reasons. Some are to do with the larger quad channel memory interface, some may be down to the larger amount of PCI-E 3 lanes that can come from some compatible chips (40 vs 16 on Skylake)
[calm down Dave I said 'some'!!!!] but some of them are due to the need to supply more power to keep six cores juiced with a suitably stable current. Asus even added contacts for more than 2011 pins on their X99 motherboards to supply even more power to the CPU to aid overclocking!
see here:
http://rog.asus.com/347222014/rampa...usive-oc-socket-extra-pins-extra-performance/
For this reason I think it may not even be practically possible to make a hex cored socket 1151 processor simply because the socket was never envisaged to support it. I'm not saying its necessarily impossible but you have to understand that adding two cores to a CPU to make in a hex core and then trying to overclock it like a quad is going to place much more demand on a chipset and motherboard especially when the CPU is manufactured on the same manufacturing process size as there would be no reduction in per core power requirements in this scenario.
Basically if you want a hex core + CPU in a mainstream socket then wait for more news re Cannonlake/ Union Bay which may support more than four cores
Now onto Dave..........
Z170 could be refreshed to support a 6 core Kabylake CPU - there is nothing physical stopping Intel from doing so, as pin count doesn't have anything to do with additional cores.
So you don't need any extra pins to supply stable power to a more energy hungry CPU (assuming you expect to clock it somewhere near the quad)? I think you will find that pin count does have something to do with the amount of cores the socket is designed to support given that Asus actually activated even more pins to provide extra power to CPU's on their board to assist in overclocking as above. Want to support more cores at a similar overclock (or stock clock) on the same manufacturing process??? - going to need more pins for stable power delivery
Once again your post is incorrect, you really don't have a good idea how these CPU's work, do you?
The X99 chipset only has 8 lanes of PCI V2.0 (DMI 2.0).
5820k has 28 lanes of PCI-E V3 from the CPU
Z170 chipset has 30 PCI-E V3.0 lanes (DMI 3.0).
6700K/6600K have 16 lanes of PCI-E V3 from the CPU
My post is incorrect? Z170 does not have 30 PCI-E lanes coming from the chipset it has 20!!!
Are you sure you have any idea how these CPU's work?
a 5820k/X99 as a total of 28 PCI-E 3.0 lanes (from the CPU) and 8 PCIE 2.0 lanes (from the chipset)
a 6700k/Z170 has 16 PCIE-E 3.0 lanes from the CPU (solely for GPU use) and 20 PCIE-E 3.0 lanes from the chipset (that cant be used for GPU's)
I clearly used the phrase 'up to' for this very reason in my previous post.
when it comes to GPU's the 5820k is still superior and more flexible because it can run the following (ignoring X4 AMD usage)
X16
X16 X8 - SLI
X8 X8 X8 - tri SLI
the 6700k can run
X16
or
X8 X8 SLI
assuming no PLX chips are used
So, for example, both CPU's are limited to running an SLI config at 8x/8x
Math's fail, a 5820k is not limited to X8 X8, it can do X16 X8 and still have four lanes spare for a PCI-E SSD attached to a 3.0 slot (whilst still also having eight PCI-E 2 lanes available as well
Also, do you have any idea how high the 6700k's even overclock to? 4.6Ghz is the minimum - as confirmed by 8 pack. My samples does 4.9Ghz, there have been many people on forums getting 4.8-5.0 on similar cooling to what x99 users use.
There's no way in hell the average 5820k is going to clock to 4.7-4.9Ghz on AIO water coolers - only the most golden samples have any hope at this.
What does your own 5820k clock to I wonder? 4.3Ghz-4.4Ghz is my bet.
Are you incapable of reading my sig where I state [email protected]???
And would that be the same 8pack that said:
'What was surprising for me about these results is that as expected on all multi threaded stuff the X99 platform smashes the Z170 Skylake. Terregan and Cinebench both heavily multi threaded benefiting from both cores and threads as do games based physics or combined tests.
What I did not expect and what is certain is in 3D game based benches the FPS was very very close indeed with Skylake faster yes but only by around 2-3% in 3D mark 11 and Firestrike. This makes X99 look amazing value considering its other benefits. '
'For me at this specific price point X99 is king and does not need high speeed DDR4 to achieve this position.'

If I pump over 1.4 volts into my CPU I can run some benchmarks at 4.6ghz but I don't bother because 1.4 volts+ is too much for daily use
Reviews don't seem to suggest that the average overclocked 6700k beats the average overclocked 5820k by more than circa 200mhz
5820k
========
'4.5Ghz seems to be a safe bet for most 5820K chips' (1.3 volts)

4.4ghz on a 5820k (At 1.3V)
http://www.overclock3d.net/reviews/cpu_mainboard/intel_core_i7_5820k_review/1
'CPU | Frequency | Voltage
5960X | 4.6GHz | 1.30V = Good Result
(given below for 5820k - 4.7ghz - 4.8 ghz)
5960X | 4.5GHz | 1.30V = Average Result
(given below for 5820k - 4.6ghz - 4.7 ghz)
5960X | 4.4GHz | 1.30V = Fair Result
(given below for 5820k - 4.5ghz - 4.6 ghz)
Overall for the 5960X we’re looking at around 100MHz lower than the (Ivy-E) 4960X, but with two extra cores in tow, which is more than respectable.
For those of you wondering about the K parts. They are easier to OC on air and water due to having fewer cores, thus less heat to contend with and higher voltages are possible. The end result is the possibility of overclocking the 6-core K series CPUs 100~200MHz higher than the 8-core 5960X.'

'4800 MHz stable but we needed a rather high ~1.450 Volts for that.'
- well if you're happy running 1.45 volts through your CPU for more than a few suicide runs then feel free!!!

'To add to the mix, I have had two different manufacturers (MSI and ASUS) both confirm that internally they are seeing the majority of their samples hit around the 4.6 GHz mark, and it seems to be very consistent. A couple of my fellow reviewers have also been in contact with what they have, with more reports around the 4.6-4.7 GHz mark, some at 4.8 GHz and one even at 5.0 GHz at 1.45 volts, although I wasn’t told of the stability at that point.'

So 5820k's overclock in the region of 4.4 - 4.6ghz and 6700k's in the region of 4.6 - 4.8ghz i.e. about 200mhz difference on average. I highly doubt you have a 6700k that can stably run anything at 5ghz.
I have consistently stated that the average overclocking difference between the two chips is around 200mhz. Shock horror CPU with more cores doesn't clock quite as well as CPU with 50% less cores!
I have posted lots of referenced links to support my position Dave you have referenced nothing but your own opinion. Care to show some references to support your claims or are you just full of bluster and marketing nonsense?
