Skylake-S and the LGA1151 (100 Series Chipsets) Platform were launched in August 5, 2015. Unlocked multiplier Core i7 6700K and Core i5 6600K are available worldwide since early August. On September 1st Intel launched Core i5 6400, Core i5 6500, Core i5 6600 and Core i7 6700 (locked multiplier). Core i3 and Pentium models were made available on the same day in Asia, and at the end of September in other regions.
Skylake was officially published in IDF held in San Francisco in August (15th)
Desktop Skylake-S Core i5 and Core i7 said:Intel's 14nm Skylake processors and 100-series chipsets for desktops were unveiled in early August at Gamescom in Germany. Intel announced Core i7-6700K and Core i5-6600K as well as Z170 chipsets initially targeting gamers.
Gamescom is the major trade fair for video games held annually at the Koelnmesse in Cologne. 2015 edition was held on 5th-9th August.
Intel unveiled Skylake-based Core i7-6700/6700T, Core i5-6600, 6500, 6400, 6600T, 6500T and 6400T, and H170 and B150 chipsets on September 1st.
The H110 chipsets were released between September 27-October 3, while the Q170 and Q150 chipsets are set for October or November.
Desktop Skylake-S Core i3 and Pentium said:Upcoming Core i3 standard-power SKUs are i3-6100, i3-6300 and i3-6320, and there will be also Core i3-6100T and i3-6300T low power processors. As can be seen from model numbers, Intel will continue to offer two lines of Core i3 microprocessors, possibly with different cache sizes and/or GPU types.
New Pentium processors are G4400, G4400T, G4500, G4500T and G4520. Pentium and Core i3 model numbers with "T" suffix are rated at 35 Watt TDP, and remaining SKUs have 65 Watt TDP. Even though Pentium and Core i3 "Skylake" products will be announced on September 1, they will not be available in stores until the end of September (except Asia). The same is true for the H110, Q150 and Q170 chipsets.
Locked multiplier Core i5 and i7 CPUs will be available on September 1st. Core i3s and Pentiums should be available on the same day in Asia, and at the end of September in other regions.
Full Lineup - Skylake-S, Skylake-Y, Skylake-U, Skylake-H, Skylake-EP/EX (Purley)Mobile Skylake-H said:The official availability date of consumer models in Asia Pacific region, China and Japan is September 1. That includes Core i3-6100H, i5-6300HQ, i7-6820HK and i7-6700HQ "H" series processors, Core i3-6100U, i5-6200U, i5-6300U, i7-6500U and i7-6600U "U" series 15 Watt parts, and Core M 6Y30, 6Y54, 6Y57 and 6Y75 SKUs. The consumer microprocessors will be released on September 27 in other regions. Business-oriented models will be available on October 27. These models are Core i5-6440HQ, i7-6820HQ and i7-6920HQ. Xeon E3-1505M v5 and E3-1535M v5 CPUs for mobile workstations will be also available on that date. In November, Intel is going to launch Pentium 4405U and 4405Y. Mobile Celeron 3855U and 3955U will be introduced in Q1 2016.

Performance (from actual reviews, August 2015)
Results from PCLab's review, Haswell vs Skylake - both overclocked to 4.5GHz for an optimal IPC comparison.
Core i5 6600K vs Core i5 4690K at fixed 4.5GHz, Skylake is:
16.2% faster @ Battlefield 4 MP
10.9% faster @ Counter Strife Global Offensive
6% faster @ Crysis 3
22.7% faster @ Far Cry 4
13% faster @ GTA V
12.5% faster @ The Witcher 3
9.2% faster @ Watch Dogs
14.7% faster @ Project Cars
14.8% faster @ Starcraft 2
24.5% faster @ Total War Attila
Overall gaming performance per clock (IPC) from 14 games/tests @ 1080p Ultra:
Sandy Bridge to Haswell: 13.5%
Haswell to Skylake: 12.8%
Skylake is faster than Broadwell with eDRAM.
Here's results and quotes from another review, Eurogamer compared 4 generations of Core i5 running the latest titles at 1080p.
Core i5 6600K is their default choice for CPU intensive games.
In the games tested by Eurogamer Core i5 6600K (Skylake-S) provides a larger performance per clock performance gain than Core i5 4690K (Haswell) compared to Core i5 2500K (Sandy Bridge).Eurogamer said:...a fully maxed GTA 5 is CPU-limited even on an overclocked Core i7 4790K, while certain scenes in the Witcher 3 on ultra settings can also cause difficulties for even the most powerful processor. Our contention is that more games like this will come along, and in demanding CPU titles, the Core i5 6600K will make a noticeable difference.
But in the here and now, the Core i5 6600K is a strong product - at worst it provides mildly enhanced performance over its predecessors, at best it's noticeably faster and should help to reduce CPU bottlenecking during gameplay. For those looking to buy or construct a new, capable gaming PC, the i5 remains the default choice and the 6600K is the best iteration yet - AMD's older eight-core FX chips are cheaper, but our tests clearly demonstrate that despite the low-power many-core set-up of the new console CPUs, modern games generally prefer the high per-core performance that Intel provides.
Core i5 6600K vs Core i5 4690K (same 3.5-3.9GHz base/turbo)
- 17% faster @ The Witcher 3
- 11% faster @ GTA V
- 10% faster @ Battlefield 4
Core i5 6600K vs Core i5 3570K (3.5-3.9GHz vs 3.4-3.8GHz base/turbo)

- 18.1% faster @ Battlefield 4
Core i5 6600K vs Core i5 2500K (3.5-3.9GHz vs 3.3-3.7GHz base/turbo)
- 25.8% faster @ The Witcher 3

- 25% faster @ Battlefield 4
Core i5 4690K vs Core i5 2500K (3.5-3.9GHz vs 3.3-3.7GHz base/turbo, ~6% clock advantage)
- 7.3% faster @ The Witcher 3
- 11.9% faster @ GTA V
- 14.1% faster @ Battlefield 4
Skylake-S supports DDR3L and DDR4 memory.
Finally desktop Haswell gets a proper replacement.

The first performance benchmarks of Intel’s next generation Skylake, Core i7-6700K have been leaked against the Devil’s Canyon based Core i7-4790K by TechBang. The results which compare the performance of the Core i7-6700K 14 nm processor versus the 22nm Core i7-4790K were tested on their specific platforms which include the Z170 for Skylake and Z97 for Devil’s Canyon.
The performance results can be seen below, do note that the Sisoft Sandra scores represent Core i7-6700K in blue and the Core i7-4790K in red. The performance results show significant gains over Core i7-4790K which is one of the fastest processor available in the market today. The Core i7-6700K scores around the same as a stock Core i7-5820K which is impressive since the latter is a 6 core beast in the Haswell-E lineup. Price wise, the processor is going to stick to the reference MSRP of unlocked flagships around $329-$339 US. The results are preliminary at the moment since proper BIOS and driver updates are yet to roll out for the CPU and iGPU.
www.techbang.com/posts/24629-skylake-intrudes-ecs-z170-claymore-motherboard-measured-experience?page=2But even Skylake launch plan has been imminent, the hardware that can be achieved at the moment, drivers, software, etc., are not the final official version, including the protagonist Z170-Claymore motherboard versa. Therefore, we believe can only spy or two, is not the time to make absolutely commented, formal and more complete testing and comment, left various manufacturers then the arrival of the official product. Let us wait and see!
13.1% better performance from Core i7 6700K at stock (overall).
Core i7 6700K: 79,73Mpix/s/GHz
Core i7 4790K: 67,42Mpix/s/GHz
18.25% better performance per clock.
Comparison - Skylake Iris Pro GT4e (72 EUs, 128MB eDRAM) vs Broadwell-K vs Maxwell
Based on Broadwell-K's 3DMark 11 results and mikk's leak (up to 50% faster) we can roughly estimate how a ~65W TDP Skylake 4C+GT4e would perform under 3DMark 11.
Core i7 5775C (Broadwell 4C+GT3e): 3057 points
Skylake 4C+GT4e (estimated): ~4585 points
Maxwell Geforce GTX850M/GTX950M-based notebooks (running Intel quad-core mobile CPUs): 4150-4680 points
Skylake Successor - Kabylake (2016)
Little is know about it in the moment, current rumours point to a 14nm chip packing higher clocked x86 Skylake cores and a new graphics architecture (Gen 10). Kabylake will introduce a quad-core variant with GT4e graphics and 2x 128MB eDRAM (twice the bandwidth of Broadwell GT3e/Skylake GT4e's 128MB eDRAM).
