    I am interested in the latest Dell Inspiron 15 7580, with the upgraded Intel Whiskey Lake CPUs (i5-8265u and i7-8665u), coming with the Nvidia MX150, 2 RAM slots (up to 32 GB), dual storage (M2 + SATA) and a matte FHD IPS screen.

    Since I can't find any reviews on the latest 15 7000 gen, I'm looking for current owners opinions about:

    - CPU and GPU temperatures: I've read that the previous versions of the Inspiron with the 940MX / MX130 had throttling issues with the GPUs hardly capped at 70-72 °C. I don't if these issues were later solved by a BIOS update.

    - Display quality, in particular in terms of brightness and contrast.

    - System noise: both in terms of fan noise and crackling electric sounds (e.g. coil whine)

    I'm also looking for information on this model and the only thing I found is a video on YouTube this week:



    Maybe you find some answers un this video.

    I just ordered the 14" version of the 'New' Inspiron series from Dell in Canada. I really wanted the 15" version as the weight difference is only about 0.75 lbs compared to the 14" but the price difference was not worth it. My configuration comes with an i5-8250U, MX-150 2GB, 1080P IPS and 256GB NVME SSD (swapping this out for my nephew's laptop). The 15" version has two memory slots, a bigger touchpad, USB-C and matte IPS screen. The 14" version only has one memory slot (single channel) and smaller form factor but also cost a lot less with sale promotion and student coupon applied. I can post an update on this thread when the laptop arrives and I've used it enough to know any flaws eg: coil and throttling. I don't think 2018 Inspiron 7000 series has a coil whine problem since I was contemplating between the Inspiron 14 and Latitude 14 with bigger battery but clearly has a coil whine issue from Notebookcheck.net review.

    For the price though, I'd lean more towards the Huawei Matebook D (15.6") and the Asus S530 (15.6").

    Both of which are cheaper and lighter than the Dell 15 7000.

    If I didn't need a laptop right now, I would have waited for the Black Friday and got the Matebook D (on sale for introductory price in the summer but I missed the deal).

    What are your quality impressions of this DELL 15 7000?
    The screen, the keyboard, the material of the chassis, the construction.

    removing the weight issue that things you liked?

    I have had my 7580 for just a couple of days now. So far, I am relatively happy with everything but the display. I have the base HD display but it cannot compare with the one in my 6 year old XPS laptop. The colors are just not as vivid and the red is more of an orange than a true red. Overall the colors are just too warm. Still, if I had not compared them side by side, I probably would have been happy. You would think that after 6 years they would have improved the display, not made it worse.

    I have not pushed my laptop much yet, so I cannot comment on noise or heat. So far it is quiet and barely warm.

    My thoughts exactly, I've had my Dell 14 7000 for a few days. Build quality is superb, keyboard is excellent and trackpad is small but precise.

    The screen is just average but if there's nothing beside it to directly compare it to, it's not too bad.

    I'm able to undervolt by -100mv for the 8250U (stress tested with Prime95) and 850mv curve for the MX150.

    The BIOS has a TDP throttle though, 20W max for the CPU/IGP under absolute full load.

    Throttling does not happen in any games I've tried, it only happens with RealBench when the CPU, IGP and MX150 are all under full load.

    Temps are good, max CPU is 85 degrees Celsius (RealBench) and MX150 is 65 degrees Celsius (RealBench).

    Cinebench R15: 8250U - impressive score of 700 CB average and great score of 80 FPS average (single channel).

    Planning on repaste with Liquid Metal after the 30 day return window expires.

    *I was highly considering the Lenovo 720S which has a great screen, better keyboard/trackpad and larger battery. However, the 720S has massive throttling issues, unpredictable fan noise and no 2.5" hard drive expansion.*

    Been playing with ThrottleStop for a couple days, I cannot remove the 20W TDP limit of the CPU, however I raise the Turbo Time Limit to 24 hours.

    CineBench R15 is now constant 715 CB, 20W TDP still kicks in 5 minutes into 100% full load (locked in BIOS).

    MX150 can be undervolt to 800mv with max temp of 60 degrees Celsius, however Heaven benchmarks 10% less FPS.

    This is the same for the GTX 1050 in my G3, it can be undervolted to 800mv but 850mv gives 10% more performance.

    So far I'm happy with this mobile machine that does not have any major throttling issue when temps are kept in check.

    After playing with my new 7580 a bit more, I am less and less happy with the display. Again, if I did not have another laptop to compare it to, maybe I would have been okay with it. The color are just dull and it looks as if only half the color gamut is used. My magenta looks pink, the reds look orange, and the deep blue you would expect to see is closer to sky blue.
    I was rather shocked to see that the monitor color depth reported by Windows is only 6-bit instead of 8-bit. Is that normal for laptops? My wife's HP x360 laptop is 8 bit and the colors on hers is much better. Looking at a smooth gradient color map (from Wikipedia), it does seem pretty bad. I can't imagine anyone using this laptop for any photography or graphic art applications unless another monitor is used. Still, everything else seems pretty good; I just hope I can live with the display.
    The only problem I have seen so far is that occasionally videos on the web play at half or quarter speed. Closing the browser tab and restarting seems to fix it.
