Intel Core i7 "Broadwell-E" Lineup to Feature Four SKUs
Intel is breaking away from its tradition of three Core i7 HEDT (high-end desktop) processors per generation, capturing price points of $400, $600, and $1000; with its upcoming Core i7 "Broadwell-E" HEDT lineup. According to leaked documents accessed by BenchLife.info, the company is readying four SKUs based on the 14 nm "Broadwell-E" silicon, these include the Core i7-6800K, the Core i7-6850K, the Core i7-6900K, and the Core i7-6950X.
The Core i7-6800K and i7-6850K are six-core chips, with HyperThreading enabling 12 logical CPUs, and 15 MB shared L3 cache. The i7-6800K is clocked at 3.40 GHz, with a 3.60 GHz Turbo Boost frequency. The i7-6850K is a notch above, with 3.60 GHz core, and 3.80 GHz Turbo Boost frequency. The slide doesn't mention if either of the two parts feature a limited PCIe root complex, like the one on the i7-5820K.
As we move up the lineup, there's the Core i7-6900K. This is an eight-core chip, with HyperThreading enabling 16 logical CPUs, and with 20 MB L3 cache at its disposal. Its core is clocked at 3.20 GHz, with a rather healthy 3.70 GHz Turbo Boost. At the very top of the lineup, is the Core i7-6950X. Intel's first consumer 10-core chip, with HyperThreading giving your OS a whopping 20 logical CPUs to deal with, this chip features 25 MB L3 cache, and is clocked at 3.00 GHz, with 3.50 GHz Turbo Boost.
All four chips in the lineup feature 140W TDP, unlocked base-clock multipliers, and will be compatible with existing socket LGA2011v3 motherboards with firmware updates. The low clock speeds on some of these chips right off the bat, could be Intel's way of not letting the rated TDP be higher than 140W. With the right cooling, the target consumers of these chips could overclock these chips.
Intel is planning to launch these Core i7 "Broadwell-E" chips in the second quarter of 2016.

One would assume "Up to" implies something is going to get gimped.
they said skylake was the only way forward well......" INTEL SEEM TO DISAGREE"
going foward that they need to solve
with more equipment uterlising PCIe ( add in cards ect ) there is going to be a bottleneck re available PCIx lanes
Hopefully thats something they need to sort out on the next release
Looks like Broadwell-E is more of a "Haswell-E Refresh" ...
our 8 core 16 thread xeons are 55w the 18 core / 36 thread chips are 145w and they have 6 cores at 140w?
I don't get it
In terms of actual configurations, 5820K has 16 + 8 PCIe 3.0 for graphics, 4 PCIe 3.0 for add-in cards and 8 PCIe 2.0 from X99 whereas 6700K has 8 + 8 PCIe 3.0 for graphics and 20 PCIe 3.0 from Z170 for everything else. If there are SLI/Xfire setup in your system, then 5820K is the winner here (although there is literally no performance difference between 16 + 8 and 8 + 8 for SLI/Xfire). For systems with a single graphics card, Z170 is actually more flexible. Also remember everything connected to the X99 PCH is limited by DMI 2.0.
Now Skylake-E will change the entire game with its upcoming X290 chipset (a guess for the name based on Intel naming convention).
Max # of PCI Express Lanes 16 taken from here or is INTEL lieing

Remember its CPU PCIx lanes not chipset lanes
now haswell on the other hand, that might make more sense. like my 4790k 4 cores at 88w vs 8 at 140 but with lower clocks that makes sense. The 6 core simply being the low bin of the bunch and the 10 core being the high bin.
Edit: I should clarify, 4 usable. The Chipset provides but manufacturers designate the extra available lanes to other features of the board. On X99 you have Up to 40 lanes usable off the CPU itself while retaining the 8 2.0 lanes off the PCH. This in itself is more usable to the user if requiring a lot of expandability not offered on the board itself. The 5820k still offering more usable lanes even at a measly 28.
Note that it's "total cache" not L3 as written in this article.
On Intel Core architecture, the higher level caches include the lower level ones (L3 always has a copy of the contents of L2 and so on). So this probably means "usable cache", which is the same as L3.
hell I'm all for performance but if semi trucks were getting 60 mpg on a new tech and were able to haul even more and you went to buy a consumer grade truck with the same tech and it got 10mpg wouldn't you be perturbed?
