    I'm sure this isn't the max, but an additional 200 points over that 9880H looks pretty good. 1949 is all I can edge out tonight. Temps aren't even getting to 90c so temps aren't my problem. Single run speed runs to get to this, pretty sure I couldn't loop stably this high. Some very odd behaviors at play when you get to these speeds trying to get the chip happy and stable. Setting the core multiplier too high lowers performance even when the core does not go above 4.5 / 4.6 ghz. I'm determined to break 2000 on R15, just need to figure out how to keep it at 4.9 turbo which it will happily do for short periods on all cores.

    Probably going to be limited by power delivery on motherboard..

    I think you are right. I believe 140w to be the max +/- 5w.

    2000 R15 surpassed with a 2010 score. I got to 2016 but then it crashed. These settings appear to be somewhat stable, but moving the 8 core multiplier to 48 leads to a lower score and -.145 undervolt is unstable. Believe I may be close to the max, and hit this with a max temp of 83c.

    What Cashe ratio you run? Tried lower it and put 8 cores @48?

    It's the all-silicon lottery if you ask me. Sure, out of 1000 processors, this just might be the one to hit those higher clocks without eating 150W of power.
    Ever since the 8000 series from Intel, it was evident that there are gross power consumption / thermal dissipation inconsistencies across processors of the same model.

    Gone are the days when a 45W or 55W TDP was giving you exactly 55W TDP @ Max Turbo.

    CB R20 --> i9-8950HK --> 3.600 = Power Limits and K matters

    This! basically we all kept paying money for an old architecture with no real upgrades except for more cores of the same architecture since skylake. Power usage literally doubled and morewhile they keep smacking the 45watt tdp label in it and just state "only for base clocks" Yet they all advertise with max boost clocks.

    It’s still up to the ODM/OEM manufacturer’s if they want cap long time Power at 45W and cap PL2 at 1.25:) Intel recommendation for unlocked BGA from 8th gen is 100/125w. But as usual... Thin and light come always first before needed cooling capacity. Can’t fill up 1 liter plastic bag with 2 liter water.

    Only for a short time boost. Intel isnt very up front of it because they still reference a cooling design for 45watt TDP which isnt true at all. 45watt TDP cooling solutions of 2 generations ago could keep a 7700HQ running at 24/7 boost clock at just 45watt power usage. The same size heatsink now even without GPU load can only cool the follow up 8750HQ at around base clocks in Prime95.
