Dell Precision 16 7680 review – overheating and underdelivering on battery life


    Temperatures and comfort, Battery Life

    Max CPU load

    In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.

    This laptop can’t sustain high clocks for long periods of time. However, in short loads, it is decent. In our view, the thermal management is not the only issue, as the 180W charger, can’t really let you max out the CPU (we’ve seen HX-series processors work at nearly 200W on some devices).

    Real-life gaming

    Here, we see no throttling in the GPU temperature test. As you can see, the device runs its RTX 2000 Ada Generation at 67W.

    Comfort during combined load

    So, the device is not too loud, which is good, and its large fans should be pushing a lot of air at a low speed. However, the externals of the laptop can get pretty warm. Here, you can see an IR image of the base, while the hotspot of the bottom panel reaches nearly 54°C, which is definitely not ideal. We wouldn’t recommend using the device on your lap.

    Battery

    Now, we conduct the battery tests with Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. This machine’s 83Wh battery pack lasts for 3 hours and 17 minutes of Web browsing, or 2 hours and 59 minutes of video playback.

    Brightness: 180 nits; Display Mode: SDR
    Time to Full Discharge: Higher is Better

    In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.

    No 2.5G ethernet for the top tier mobile workstation model!? That’s ridiculous

    “+ Decent battery life – Horrendous battery life”

    Are you serious ?

    Unfortunately, the latter is the right one, my colleague has made a mistake, and thank you for pointing it out! The Precision 7680 is indeed one of the laptops with the shortest battery life we’ve tested, despite having a decent battery capacity.

    keyboard arrow keys completely unusable, no page up or page down. micro return key. laptop tries to heat whole house. at least its a work machine for just email and i have a non dell machine for software development
    feel sorry if you actually bought this machine
