    They at least give enough craps to release a BIOS update to attempt and fix their mess, while we rely on 3rd party to fix clevos garbage and since 7 years still waiting for a control center that isn't absolute garbage :rolleyes:

    Prema bios isn't released yet. So they are using their own one. Which seems to have the 150W EC throttling limit.

    They are just using a 180W so once prema mod hits we'll need it(we might even need 230w)

    I don't think that the EC code is specifically designed to impose the 35w limit based only on the power of the adapter.

    My guess is that, the 35w power limit is more related to the thermal headroom for the CPU when the load is combined (CPU + GPU load), so if I'm right, the limit is just there to further manage thermals under combined loads (since most of the heatsink designs are unified, the heat from the GPU is shared with the one on the CPU, meaning less thermal headroom for the CPU).

    From what I've gathered so far, most of the thin and light notebooks have the 35w limit under combined loads, but there is one notebook (the 2018 razer blade) that has a 35w limit even when the GPU is not used:

    @Prema
    Am I close to the truth with my previous assumption?

    There are throttle limits for:

    - CPU only
    - GPU only
    - CPU & GPU combined

    (Using a different AC Adapter won't change any of them).

    dingdingding we got a winner.

    I have seen GS 65 getting to the 40s but usually gets thermal throttled down again. So it's still meh.

    1 The CPU has a 45W limit, can bypass to unlimted for 28 seconds(so your first CB run scores high).
    2 The GPU has a 80W limit
    3 The system has a 150W limit.

    Lets compare number 3 with the competitors :
    1 GS65 : 180W
    2 15X : 215W
    3 RAZER : 230W

    The third one dictates if the GPU is getting 80W, the CPU can only get ~35W of power. Raise your brightness and you can choke the CPU even harder.

    Razer doesn't have a 35W limit. The CPU locking to 35W is a bug/safety feature as not everyone is getting it. Razer has set the CPU TDP to 60W from 45W.

    Assuming streaming + gaming load :

    The gigabyte can hold 3.7ghz.
    The GS65 can do 3.7ghz if it wasn't for MSI retarded overvolting. Holds 3.4ghz
    The razer can do 3.9ghz due to the raised TDP.
    The clevo is a rollercoaster between 2.2ghz and 3.9ghz, murdering any chance of a streaming + gaming



    Don't **** on all thin and light laptop because of clevo. Let's not forget that these are XPS 15 sized laptops(not the clevo as the P955 is larger) that pack one hell of a punch.

    I think you don't mean XPS, I think you mean the G series. They are indeed not to shabby, especially considering the price. Also HP Omen seems to be a valid option as well.

    No I mean XPS . The G series are thick and heavy

    Lets compare dimensions between XPS 15 vs GS65

    GS 65 : 14.06'×9.72'× 0.7'
    XPS 15 : 14.06'×9.27'×0.66'

    Weight
    GS65 : 4.1lb
    XPS 15(97Whr) : 4.5lb

    The RB 2018 and aero 15x are similar.

    These are amazing notebooks. Don't generalize clevo issues.

    RB are build to die, hence I consider them worse than Clevo. Also XPS don't have better GPU than GTX 1050 so idk if you should even compare it.

    This is a point of praise for the 'thin and lights'(P955 excluded) . As they packed 92~87% of gtx 1070 performance in an XPS like chassis while keeping the I7 8750H throttling to a minimum.

    I don't reccomend razer.

    Clevo has the larger chassis and the better cooling. I have faith that prema can make it outperform even a RB2018.
