    Latest DELL Precision motherboard photo outflow: graphics card heterotypic

    At present, a net friend "leech.yea" found a picture of the main board of the latest DELL Precision 7 series from the post bar. At present, it is not yet final to determine the 17 inch Precision 7730 or the 15 inch Precision 7530.
    But the design of the two fan with its distinct characteristics shows that this is the product of DELL. The left chip is GPU and the right chip is BGA on the motherboard CPU.

    From the picture, we can clearly see the annotation near the memory slot, which proves that the motherboard design was basically fixed in the 2017-07-25 before the first half year.

    Take a closer look at the information tagged on GPU, which is N18E-Q1, which should be NVIDIA Quadro P3200.
    The annotation information above in Figure 003 - GPU
    [​IMG]

    The NVIDIA Quadro P3200 has a 6GB GDDR5 memory, and the following 8 display pads around the card chip in the next figure are only 6 welded, and each 1GB is exactly 6GB.
    However, it is more important that the Internet users find that the video card is not a standard MXM structure, but is connected by a line and a main board, seems to use an external power supply, and has a display port on the board's circuit board.

    Then, a net friend "moon shadow" in the water further analyzed the above picture and concluded that the main board was the 17 - inch Precision 7730 main board, the reason for the four ports on the side of the video card, and the back interface of the DELL Precision 7730 official picture. At the same time, it is regrettable that such a video card can not upgrade itself, at least it does not support the MXM interface, and the future upgrade becomes very small. Do you have any information? Is this the trend of development in the future, or is it only DELL's own work? Reference 6500 of the video card generation is out of print.
    Figure 005 - four ports on the front side of the main board.

    However, at the same time, the Internet user "big D-Daring", as a mobile workstation DELL Precision series for many years super dealers, which said that this should be the 15 inch Precision 7530 main board.
    Indeed, this year, the DELL Precision series is further improved than the previous model, but the 15 inch model also uses a NVIDIA Quadro P3200 with a good performance.

    So, what is the truth?

    Thank you for waiting for the DELL Precision 7730 Review: the world's first!

    Great find...
    So, Precision 7X30 doesn't use MXM graphics cards anymore... I'm disappointed but not tremendously surprised. They already ditched MXM in the Alienware line, the other place where it would totally make sense to have it.

    This custom design is probably how they managed to get the Quadro P3200 into the 15" Precision 7530. (Too bad it's not a MXM 3.0a card. That would be an awesome upgrade for prior 15" systems.) This also allows them to shave some millimeters off of the system height.

    At least the GPU is a discrete component, separate from the motherboard, so upgrades from i.e. Quadro P3200 to P5200 will be possible.

    I would speculate that this is Dell's own design and not a new standard form factor, but I guess we don't know for sure until we see what HP and/or Lenovo did with their next-gen systems.

    I suppose there is a small chance that the GPU could be upgraded down the line, if the Precision 7X40 (and maybe 7X50) use the same chassis, and Dell uses the same GPU form factor and interconnection? (Dell has got to know that there is a group of people who are very interested in GPU upgrades to extend the life of the system, maybe they won't totally break it...)

    I'm not clear on how the GPU is actually connected to the system, from the pictures. It looks totally separate, aside from that red/black cable that is connected, but that looks more like a power cable to me? Is there something on the flip side of the card? All of the pictures seem to be of the same side.

    And from the "holes" cut out for the fans, we have a hint at the cooling system for this laptop, that's a pretty big space left for the fans. Will they have two fans on each side, or one fan that is sort of large? (There are two exhaust ports...)

    What you said above, I have the same opinion.
    Further information on Precision 7*30 will give more detailed information in these days.

    OMG, luckily i have bought 7720, which represents the last model of precision that offers MXM + old dock slot. 7730 is a joke, I will have to go for Clevo after this 7720 retires, i hope it can go on for another 3 to 4 years.

    With this, there is no necessity to search further info for 7730 anymore.

    Thanks big song for sharing this.

    The move away from MXM is not a Dell decision but the graphics vendors decision. They have all stopped making MXM cards. We had to either design our own graphic cards or put the GPU down on the motherboard which is really not something I wanted to do.

    So, this is Dell's unique design. Nice.

    Dropping the GPU right on the motherboard seems like it would cause trouble with a system like this... Dell already has to produce effectively a different motherboard variant for each CPU offered, as the CPU is soldered. So, if the GPU were also soldered, they'd be looking at a different motherboard variant for each CPU/GPU combination (and also likely placing limits on such combinations).

    This also means that there will probably not be MXM Quadro cards that are any better than those already available (Quadro P5000 at the top). I wonder if we will see MXM GeForce cards going away when NVIDIA's next generation launches later this year. Seems like there is more of a market for those, but the market has clearly been moving away from it — There were way more systems with MXM slots and GeForce 9XX GPUs than there were with GeForce 10XX GPUs, and the GeForce 1080 needed a custom design and seemed to be different everywhere, even if it had an MXM interface anyway.

    Still interested to see what Lenovo and HP have come up with...

    But HP Zbook 17 G5 still supports MXM graphic cards. [​IMG]

    I wonder if HP has opted to produce their own MXM cards ...?
    Anyway, the P5200 needs more than 100W of power (typical maximum for the MXM interface), so either HP is going for a max-Q version of the P5200, or there's still a missing piece here.

    That means MXM card for P5200 still possible :). Any i believe Clevo will have this version of MXM card too.

    ===============
    I think Clevo will have at least a MXM version of GTX1180
