    The TDP is for full load at base clocks usually.

    The gap between base clock (TDP) consumption and performance when uncapped will be even greater with an 8 core

    If the i9-9980HK is a 2.4ghz base as I suspect (and 9880H 2.3), if their all core turbo is up near 4GHz they will need >100W to not power throttle even under turbo. The difference between what the same CPU can actually perform at in a monster GT75 vs a throttling mess Macbook Pro will be even bigger than 8th gen

    The i9-8950hk was a $578usd tray price cpu, can't wait to see the 8 core HK price. Anything that makes owning a desktop-in-laptop P870 seem less insane by comparison is welcome :)

    It's a pity that Hyper threading is only available on the i9 for the 9th gen.

    Edit: Well the i5 has it but with 4 cores on 8 threads.

    shouldnt be a surprise, would be unusual if they changed the laptop lineup to differ from the desktop naming convention (i9 with HT, i7 8c without HT, i5 6c or 4c with HT)

    8th gen unlocked BGA is bad value and coming i9-9980HK won't be any better. On top you pay an high price for performance you can't get (often +$600).

    Our Core i9 verdict: It’s just not worth it on laptops

    With almost a dozen Core i9-8950HK laptops under our belt, we have a pretty good idea about how these unlocked CPUs can perform. Average CPU performance is just 8 to 9 percent faster than the average Core i7-8750H laptop for a disappointing first year...


    Users who really want Core i9 on a laptop ought to consider Clevo or Eurocom models as these systems carry standard LGA1151 sockets specifically designed to run desktop CPUs at comparatively higher TDP ceilings.

    OK Thx.

    I don't think they're right.

    On the leak PDF, i7-8850H is a 45W, 6 thread 12 core part with a "CTP" of 386,987.
    I chucked stuff into an excel spreadsheet, Regressing from known parts gives all the 8-cores a fudge factor of 24,500 per base clock GHz per core. i.e. 9900K and 9700K: 8 * 3.6 * 24500 = 705600.
    The fudge factor for 6-cores is different, it's about 24805.55. e.g. 8700K: 6 cores * 3.7Ghz * 24805.55 ~= 550,683. (Quad cores it's approx 25416.7 and X series are different again, I also didn't bother looking at pre-skylake)
    Regressing backwards on unknown parts on most of the assumptions (e.g. i9-9980HK & i9-9880H are 8-cores) gives round numbers on base clocks as all Intel parts have had. That's what makes me think the 9980HK has a 2.4 base and the 9880H a 2.3 base clock.

    The i7-8850H is 2.6Ghz base, 6 * 2.6 * 24805.6 ~= 386,967: exactly the same score given to the i7-9750H AND i7-9850H which makes me think they will ALSO have a 2.6 base clock and 6 cores/12 threads (because no HT makes no sense), and will only differ by having slightly higher turbo.
    Using the 8-core fudge factor on 386,967 gives an estimated base clock of 1.97 which is not a round number.

    Actually, looking at the CTP / MTOPS column, to me the new laptop CPU's look like 8 core / 8 thread sku's - no HT on the new laptop CPU's - that would explain the scaling of the CTP / MTOPS results in this table:
    intel_ctp_9th_gen.png
    I think the 8c/16t listings are incorrect and these are CPU's without HT, and therefore only 8c/8t CPU's.

    I'm pretty sure 9900k has HT
