laptop chips at 50W? Someone's going to be buying a brick.

50W is peak under all core turbo and only if the laptops cooling system can handle it. Most systems won't come anywhere near that

  This is not generally how Intel measures TDP, unless they changed something this time.

    TDP is 15W, max turbo is 50W (if the laptop can handle it).
    - sudosysgen 6y ago
      The 15W processors don't turbo to 4.8Mhz (Oops! Ghz), though.

        Because surely they're many orders of magnitude faster? :)

        Good catch!

        The i7-1185G7 [1] has a 15W TDP and it will hit 4.8GHz, although maybe for a short time. So yeah, it's 100MHz slower than the i7-10810U [2] (I don't know if you can even buy that) but actual performance should be higher.

Intel appears to have eliminated the concept of a "standard" TDP and now it sounds like the laptop maker can set it anywhere within the range of 12-28W.

        For a while the i7-10810U was an option on the late 7th gen X1 Carbon, though you could only order it with the 1080p display. It was also an option on the 8th gen X1 Carbon[1], but it looks like they've since pulled it. The fastest CPU you can get on it now is the i7-10610U, which turbo boosts to 4.9GHz but only has 4 cores instead of 6. I have the i5-10210U which turbo boosts up to 4.2GHz. Intel lists its TDP as 15 watts, but if I stress test it in s-tui[2] it spends several seconds at 47 watts before being throttled due to thermal constraints. 1. https://www.notebookcheck.net/Intel-Core-i7-10810U-ThinkPad-X1-Carbon-Gen-8-listing-reveals-new-Comet-Lake-hexa-core-CPU-with-vPro.452705.0.html https://www.notebookcheck.net/Intel-Core-i7-10810U-ThinkPad-... 2. https://github.com/amanusk/s-tui https://github.com/amanusk/s-tui

  Which also means that most machines will not see any numbers mentioned here.
