    Don't you think they'd have a desktop/server part already if it was clocking well?

    No one said otherwise.. That's, kind of the whole point. They're merely on par and have atrocious yields, hence why only a quad core was taped out and the 10 series notebook chips will be a mashup of ~3 Icelake SKUs and the rest comet lake-U.

    It's not a matter of how fast Icelake will be on the desktop - but when they will be fast enough or high yielding enough to bother.

    Yep.

    And my basic premise is *what if?*

    WHAT IF 5ghz is the ceiling and ~14nm is the sweet spot of the overlapping yeild/clock/interference/voltage/thermal curves either side of which performance declines?

    Then there has to be a plan B.

    My speculation is that a POSSIBLE plan b would be to bundle a couple of "fast" cores on a "sweet" process for single threaded apps with a bunch of "slow" cores for everything else - like a GPU kinda is.

    the sunny cove/ 10nm power/clock scaling is terrible, as a result the "cheaper" comet lake U is going ice lake in most benchmarks as whiskey lake is about par with ice lake at iso power. Also consider that ice-lake U is bursting upto 45watts for ~8 seconds.

    https://www.anandtech.com/show/14664/testing-intel-ice-lake-10nm

    12watt base clocks @ 700mhz....... thats like 1/2 the base clock of whiskey lake and it looks like comet is going to have much higher turbos ( have to see about base clocks).

    max single core turbo in 25watts of 3.9ghz

    More comperensive tests :
    https://au.pcmag.com/microsoft-surf...us-could-bring-major-gpu-grunt-to-new-laptops

    https://www.notebookcheck.net/Our-f...ey-outgun-the-AMD-Ryzen-7-3700U.428323.0.html

    Dear oh Dear , I think the CJ version of a response would be something along the lines of "Icefail" , but What's with the headlines on these articles though - I don't normally go down the "how much did they pay them to write that" path, but really?.......

    Gets outclassed by it's own predecessor at 15w , and the much touted Gen 11 Gfx whilst it's a good leap forward for Intel, is up against superseded tech (14/12nm Vega 10) with a massive mem BW deficit.. and it's not even an on the shelf product yet.

    Intel are fortunate AMD are spread too thin (I believe) to aggressively pursue this last bit of territory - a Zen 2+NAvi + LPDDR4 response from AMD would wipe the floor with these all round.


    It's also a big arse reference platform with it's fan pinned at 100% (To quote the Anand article) .

    It would be interesting, and more relevent to put it up against AMD and Prev Intel reference platforms as these always have best case performance

    why would I its looking pretty good to me @ 15 w beating the 9900k in some tests

    Some = 2
    Which, at a cursory glance are from the gpu portion of the chip anyway.

    Lol if you were this generous with "ryzenfail" you'd be more credible.

    ryzen isnt a 15w part clocked 1.1ghz lower than a 9900k beating a 9900k

    Do those tests even use the CPU at all or are they entirely on the GPU?

    If they're on the GPU, is the comparison AS A CPU even relevant?

    a ryzen 3900x does not have an integrated gpu

    And how much power do you think a 9900k draws under a single thread load?

    You realise the current, 15w i7 8665 runs at 4.8Ghz?

    seeing those chats im confident the desktop parts will be a step up from what we have currently

    Point is the things it won were on the igpu - which is interesting, but not really a reflection of cpu performance.

    except for it isnt as the 3900x is on the chart and does not have an igpu

    If they get their yield up. They're also pushing out Ice Lake on Xeons first to combat Epyc, and that's gonna be H1 next year. Intel allegedly have said that they will not be pursueing Ice Lake on mainstream desktop as of yet, and may skip this generation in favour of the more mature 14nm node, and 10nm will come with next gen (Tiger Lake) to desktop.

    not really as its the best 8 core cpu you can buy currently

    But a 15W part beats it? :lol: Hey, I can cherrypick just as well as you can. I can ignore facts just as well as you can.
