Computex 2017: Intel Launches X299, Kabylake-X, and Skylake-X
Intel this summer will be releasing a new series of processor and accompanying motherboards. When you open your eyes and focus like a hawk here at Computex, you can stumble into some motherboards that actually are the new X299 platform.
Shortly after the AMD Ryzen release there was word that Intel was ramping up some new releases to address the gap in the channel that AMD is creating. The new X299 platform will hold Skylake-X and Kaby Lake-X processors. The first real announcements will be made half June according to our information
Intel is to release Skylake-X and Kaby Lake-X at the same time. The difference is simple, Skylake-X can offer 12, 10, 8 and 6 core processors (+ threads), the other (Kaby lake-X) remains to be a quad-core part.. So Kaby Lake-X CPUs on an X299 Motherboard have already been spotted in the form of the Core i7 7740K. This would be the quad-core part. New here will be the suggested support for quad-channel memory (this is not confirmed just yet and might up ending being just dual-channel). A recent SiSoft Sandra entry already has revealed the Core i7-7740K which at that point showed clock frequencies of 4.2GHz with a 4.5GHz Turbo. Kaby Lake-X CPUs thus are quad-core processors equipped with an 8MB cache and come with 16 lanes of PCIe 3.0 from the CPU, and will fit on that new X299 motherboard platform. This processor would get a 112 Watt TDP. The rumored Core i5 model is the 7640K as specced below. The Kaby-Lake-X specs are obviously unconfirmed but would entail something like this:

In the enthusiast class / range you’ll spot Skylake-X. These puppies are extreme editions much like the current 6950X series currently on Skylake-X with up-to 12 processor cores and thus 24 threads it is assumed that these processors will get a 140 Watt TDP. Skylake-X will include 12, 10, 8 and 6 core products. That 12-core version is a new one and seems to be a bit of a reaction from Intel towards AMD who will be releasing Threadripper processors with up-to 16 core parts and 32-threads.

The processors once again will need a new socket, 2066-socket, and yes that means that once again you have to purchase a new motherboard. This chipset will be called X299.
The X299 will bring quad-channel DDR4 support to compatible 14nm processors and 40 PCIe 3.0 lanes with Skylake-X procs. Kaby Lake-X procs will support dual or quad channel DDR4 and just 24 PCIe 3.0 Lanes. The new platform also offers support for Intel Optane and quad channel DDR4-2667 MHz memory. X99 will be based up-on a new socket, LGA 2066 that means that once again you have to purchase a new (X299) motherboard.
I still need to edit the full specs, please look at the charts below for full information.

3.3 ghz for the 10/20 core version, 18/36 core will go down to 2.6 probs, im guessing AMDs 16/32 cores CPU will go for $1200 give or take.
The CPU market is becoming interesting after 10 years

Hoping to pick myself up the 10/20 core one, hoping it will be around the £900 mark if those prices are correct. Though will wait to see what threadripper has in store just incase. would have prefered the 8/16 core but they gimped then PCIE lanes for some unknown reason, and the prices between the 8 and 10 seem a little to high, so maybe the 10 core might come down just a little...
Will look forward to HH reviews on all these, either way this year is setting up to be a very interesting battle between AMD and intel. looks like PC's/CPU's are going to be heading into a war between core count rather than clock speeds

I was thinking in the lines of older 8-core parts like haswell-e and broadwell-e was not a good overclocker. You had some of the 8-core ones go to 4.7ghz.
Now of course it could have changed with these. And if these really are not soldered like old HEDT cpus we might see limited overclocking partly because of that already.
i never care much about either the cpu soldered or not
because what i need is stable system rather than OC-ing for maximum performance
but if we look the positive side
isnt non-soldered CPU better, especially for OC-ing people
so they can delid easily and get even better performance ?
and for person like me that prefer stable system with cool system, well soldered might give cooler temp, but even so maybe not more than 5c considering cpu usage is usually below 50%
the impact will be "casual" OC people, that afraid/never deliding the cpu
with OC they get lil-bit hotter

If this holds true. I think it does considering whom is saying it.
Does look like they went with TIM instead of solder for both Skylake-x and Kabylake-x.
