    100 Series Chipsets PCH Specifications


    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:
    [​IMG]

    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).

    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)
    - 22.4% faster @ The Witcher 3
    - 20.6% faster @ GTA V
    - 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
    - 31,7% faster @ GTA V
    - 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.
    Compared to the older chips:

    wccftech.com/wipintel-skylake-core-...-leaked-tested-ecs-z170-claymore-motherboard/

    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)

    http://benchlife.info/cannon-lake-postpone-and-kaby-lake-will-replace-skylake-in-2016-06232015

    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).

    Good stuff! HEVC, VP8, and VP9 -- should be good for mobile form factors, too!

    Indeed. I'm impressed they managed to keep 4GHZ base clock for the Core i7 6700K too. Bring on Skylake and Gen 9 Graphics.

    Yup. I wonder what kind of perf/clock uplift Skylake will bring? If it's >=10% this will be a good release.

    Give me 15% and 4.5-5.0GHz on air and I'm happy. Broadwell was a 5.5% bump and it's a tick.

    That would be pretty awesome.

    I wonder what Intel's plans are with the "E" chips...hope we get more BDW-E leaks soon.

    (I recently picked up parts for an X99 build that I'm planning on working on this weekend...hoping X99 will have a compelling upgrade path)

    Yes! Low turbo (only 5% vs 10% on HW) is a bit concerning vis-à-vis overclocking - may be less headroom than HW :(

    I think the low Turbo is more a testament of the both choice and that 14nm hopefully exhibits the tank of monster process that was 32nm.

    Intel has no GHZ arms race anymore, so no need to go massively overboard with turbo creating more performance in segment such as ours.
    They know we're gonna tinker like idiots and probably break one or two chips along the way anyhow.

    Of course time will tell, but even if turbo could be 5,1 sustained i don't see why intel would give that for "free" for a segment such as HE Desktop.

    It's a relief after all the negative hype from 14nm.

    Ya, we just need what we get in terms of clock scaling with more voltage. The curve for 14nm is supposed to be flatter (lower increase in clocks for a given % increase in voltage vs 22nm). I'm guess that's why turbo is down from 10% to 5%.

    Still, if SKL averages 15% better (or more) IPC over HW and still clocks to 4.5 GHz, it'll be a fast CPU (plus chipset features that should improve overall system performance).

    What is a DT processor? DualThreaded?

    84->65W is a healthy bump in efficiency for mainstream. Wonder why they need 88->95W for -K despite the shrink and same frequency; does it have GT4 graphics?

    Where are those Gen9 graphics details that the title promised?

    Also, where does this information come from?

    Geez I hope that HEVC decoder is full hardware decode with 10 bit support.

    And then I hope for no bugs (like the 24p bug) and good Linux drivers.

    If this is true, I'm disappointed. Come on, still only a x4 PCIe/DMI 3.0 link to the PCH? A half decent PCIe 3.0 x4 SSD will saturate that. Forcing one to use PCIe lines from the CPU for maximum performance. Again.

    Guess I'm going Skylake-E for my next build... :cool:

    Dammit people. If you want to use French, at least spell the words correctly. It's "vis-à-vis", not "visa vi", which are a credit card and a text editor.

    If 10nm is not coming till 2017 I think we can expect another Devil's Canyon style refresh and Iris Pro GT4e variants next year. Core i7 6700K probably packs GT2 graphics.

    Thanks, my bad. BTW, it's accepted in the English language, though with the correct French spelling (like so many other foreign sayings adopted by English speakers).

    Apart from the SKUs the slides are not new to me. The only difference here is that they removed OpenGL 5.0.
