Specs on Intel Skylake IGP leak
There has been talk and gossip about the upcoming Intel Skylake IGP. Chips based on the IGP are due for launch in 2015. CPU World got a hold of new details about the Skylake GT1, GT2, GT3e and GT4e graphics. The models with the "e" suffix are the psicy ones and come with 64MB eDRAM on quad-core LGA1151 CPUs and 128MB of eDRAM on "H" series Broadwell CPUs for extra performance.
Skylake chips will come with GT2, GT3e or GT4e GPUs, built on 9th generation graphics architecture, and "e" units will be coupled with up to 128 MB of eDRAM memory for extra performance. The GT4e GPU, obviously, is the fastest one, and it will be accompanied by 64MB embedded DRAM on quad-core LGA1151 CPUs, or 128 MB eDRAM on "H" line of BGA processors. GT4e graphics will utilize 72 execution units (EUs), that is 50% more than the best Broadwell GPU, which has 48 EUs. As a result, we expect GT4e-equipped models to be far superior in 3D graphics applications and games to Broadwell chips. As for GT3e and slower GPUs, Skylake processors will have exactly the same number of EUs as Broadwell products, therefore their performance advantage over Broadwell will be only due to graphics architecture enhancements.
Skylake GT3e graphics will incorporate 48 execution units, and will have 64 MB of eDRAM cache. The GPUs will be used in "U" ultra low power systems-on-a-chip.
The most common GT2 graphics will have 24 execution units. It will be available in desktop LGA1151 CPUs, "U" 15W SoCs, "Y" SoCs and "H" series processors.
GT1.5 GPUs will come with 18 execution units (same as Broadwell), and they are going to be integrated into dual-core desktop chips for socket 1151.
Finally, GT1 graphics units will have 12 EUs, that is identical to Broadwell GT1. The GPUs will be used in dual-core socket 1151 CPUs, and in some "U" series chips with 15 Watt TDP. Via CPU world

Well that's just flat out not true.
Laptops, tablets, entry level units and workstations. Power saving, cut out the real gpu when not in use and you will likely save money in the long run for the small added cost of this igpu.
I agree with u on this but im talking high end for easier overclocking.

What are you taking about, the it company that i work for has igp on all employees laptops, we don't need high -end gpu's for server administration. Actually i think every single business laptop out there that is not use for graphics purpose has igp from intel.
So yeah, what you wish will never happen, because they come with the package, they are cheap and they are fast enough to run anything but games.
I wish they would just cut these useless igps out of the i7's amd i5K's they should realise anyone buying these is going to have a real gpu anyways just cut the costs or something ide take an extra dollar off rather then have this garbage added in.

high-end already exists without IGP, that's haswell-E
if you want high-end it's X99...the Z87 is not classed as high end to Intel
hence inclusion of IGP

They're probably focusing on the graphics side so much because the Intel graphics have the perception (rightly so) of being quite poor, and more importantly they want to 'steal' market share away from AMD's APUs. The upcoming Carizzo APU will have to be something pretty special then, despite still being Bulldozer based (Excavator core) and have Radeon graphics. The Excavator core supposedly has a larger leap in performance compared to Bulldozer --> Piledriver, or Piledriver --> Steamroller, so we'll see what happens.
It was rumoured at one stage the the unlocked desktop Skylake processors, if they actually do eventuate (they may not even make properly unlocked ones) won't be out until 2016, around the same time AMD are supposedly releasing their completely new architecture. It may be the case Intel will only release unlocked Skylake processors on Z107 Socket 1151 (not the enthusiast Skylake's) if it appears the competition from AMD is strong. The reason why they wouldn't release a properly unlocked socket 1151 processor is because they are competing with themselves a little against their enthusiast i7's. Realistically if people want to overclock, it will push them into that higher market segment which has a higher markup for Intel.

GT4e could be pretty amazing in a super thin gaming oriented ultrabook. current iris pro 5200 has 40EU and 128mb edram and does pretty well in 720 resolution can play all games on medium or high at that resolution smoothly. With 72EU + architecture improvements should easily more than double the performance of haswell iris pro 5200.
That should bring many games playable at full 1080 with medium settings and some games even high settings or 720 res and ultra detail which in many cases actually looks better than 1080 with lower detail.
This could also see great use for an HTPC/living room gaming console in 1. The only issue i see is even though intel is making great strides with the igpu it seens everytime intels igpu gets better amd's gets better and it continues to hold a pretty big margin on graphics performance. If all you want is the best gaming on igpu amd apu's are the way to go since games are gpu limited 90% of the time.
Of course none of us hardcore users care at all about igpu. my pc is over 4 years old and I still dont really have to upgrade. I was going to build an x99 but i chose to spend 3000 on a 55" LG oled and i'm glad i did picture is just wow.
