    Not so much specs as matching performance. For the work we are doing, we will need either the RTX 4000 or 5000 and I want the CPU/memory combo to be well suited for that. I was set to pull the trigger on the i9-9880H when they announced this refresh to the models. I'm sure the i9-10885H is the better value proposition without paying the Xeon/ECC tax and incurring lower memory bandwidth.

    Don't get me started on the displays... where are the 2K displays?!?!?

    The RTX 4000 and 5000 are power-starved on notebooks, and you possibly wouldn't need that much CPU horsepower to saturate the GPU, unless you're running CPU-heavy games (not likely to happen in a workplace, methinks).

    Not a lot of options there from the panel manufacturers' side; fairly run-of-the-mill displays. Dell probably thought it made more financial sense to offer FHD and then directly 4K.

    Considering most workplaces are home offices nowadays, gaming is probably a "hidden sales variable" for this class of laptop. Especially when you have high-end gaming laptops looking like computing versions of a Monster Truck Rally contestant, it is no wonder companies like Razer have toned down their decorations to appeal to this market. How many professional applications need ray tracing graphics? Compared to... how many want to play "Ray Traced Minecraft" after hours? :)

    The RTX 4000 is great for games. In fact, the same money for a Area 51m with i9-9900 and RTX 2070 can get you a 9880H and Quadro RTX 4000. You have to take the 60hz UHD display out and swap it with a 120hz FHD display yourself, but then you have a nice gaming machine without the headaches induced from Alienware Command Center. Oh, and even though GSync is not an option on Quadro's, Fast Sync does work and helps out with tearing in games that are not GPU limited.

    Someone on the owners forum posted the detailed specs and they include the i9-10885H. Of course... no mention of when it will be available.

    Found this in the Dell Precision thermals solution whitepaper:

    upload_2020-5-31_15-59-46.png

    This is incredibly intriguing as they're promising a 25% 'power improvement'. Since the current TDP limits for the CPU are 60W and 75W (in Ultra Performance mode), this evaluates to 75W and 93.75W sustained, if this is true.

    Under load, the 7540 allocates 100% GPU power (capped at 80W for RTX 3000, 4000, 5000) and 55% CPU power (TDP is 45W, so 24.75W sustained), which is in line with my own testing with the Xeon E-2286M and the RTX 3000. They're claiming an improvement to 70% CPU power under max load for the new 7550, which is 31.5W sustained when the GPU is maxed out.

    They have not mentioned any change in TDP for the GPUs of the 7550 and 7750.

    A cool bonus: the fan blades are now metal!

    Configuration 7750 contains a selection of SSD сlass 50 options. What does this mean? What are the IOPS specifications and read and write speeds of this model SSD?

    It is ambiguous and a purely qualitative description rather than quantitative. They don't provide much information, except that class 50 is better than class 40.

    I found this link. https://i.dell.com/sites/csdocument...cision_Workstation_Storage_Classification.pdf
    As we can see, this device is 2 times worse in performance than the Samsung 970 Pro (MZ-V7P512BW), which has characteristics:
    500 000 IOPS (4K blocks)
    3500 Mb/s read, 2300 Mb/s write.

    Oh seems like you found more than I did. I prefer to install my own drives (970 Pro) so it isn't too much of an issue for me, but it might be a letdown for those who want to use the drives Dell offers.
