    Pretty much the only point of the liquid cooler is being able to use an existing product. Otherwise an air cooler customised for the enclosure would be just as good with no need for the liquid and pump.

    Might as well have put a Quadro in there. This thing is going to starve for bandwidth to be of anything that isn't using CUDA or OpenCL.

    Yep, even a GTX1060 was edging towards bandwidth saturation on TB3. This is a massive waste of money.

    Youll be surprised actually :)

    TB3 40gbps = 5000 MB/s
    PCIe 3.0 x8 = 7880 MB/s
    PCIe 3.0 x4 = 3940 MB/s

    Based on this 2080TI Scaling guide

    4K Resolution:
    3.0 x16 = 100%
    3.0 x8 = 98%
    3.0 x4 = 94%


    1440p Resolution:
    3.0 x16 = 100%
    3.0 x8 = 98%
    3.0 x4 = 92%

    Considering the above and the fact that TB3 is tad faster then PCIE 3.0 x4, you can game comfortably in 1440p and 4K with almost the same settings you can on Direct attached PC, some minor tweaking, some GPU overclocking and you wont feel the difference.
    Gigabyte already has product page with spec and images.

    P.S. Everyone can agree its better then nothing and based on scaling above not THAT bad actually, and for people that ACTUALLY need such device its godsend.
    What we need is update to TB protocol that can use a pair of TB connections in unison to double the bandwidth, it will remove all the bottlenecks

    All those numbers are great, but they don't match what actually happens with these boxes. Every review of them ever published has shown that putting anything faster than a GTX1060 in one results in a massive loss in performance, and the faster the card the worse it gets.

    For one thing, TB3 is a super talky protocol, with overhead percentages in the double digits under the worst conditions. The more traffic, the worse it gets, and video cards generate a lot of traffic. If you plug in storage to the USB on the box and/or use the Ethernet port, it compounds the issue even more.

    While it's true that a TB3 box is better than nothing, you are wasting a thousand bucks putting a 2080ti in one. Stick with a 1660 class, or a 2060 at the highest end.

    yep, same old similar boxes killing 1080GTX between 1060 and 1070 in the best cases
    and price , be honest 1500e+ maybe 2k killing this box in begininig
    still price be high and be close in some whole NTB with 2070
    this external boxes maybe have future but not now and honestly not in +2 years too
    TB behavior is more than USB like PCIe, means so many latencies added and its bad thing
    resume

    overpriced
    specific used
    lower performance than you excepted in half of scenarios, maybe more

    If you are gonna pay 2K wouldn't you just get a laptop with a 2080 already in?

    Most gaming laptops are huge, the whole point of such devices is to have think good laptop with fast modern CPU that has build in graphics which battery saving and enough for everything except gaming, come back from work or university, plug in your external GPU that connected to proper PC monitor or big TV, grab a gamepad or gaming keyboard and mouse and game

    An 8 core CPU goes for around 500usd.
    Good laptop with good screen, 6/12 cpu or 8/16 CPU with data SATA SSD and NVMe for OS will be near 1K, maybe tad more tad less depending on the brand, size, parts,sale etc

    Some of those as well
    I have an eGPU setup with a 1080Ti. So glad I replaced my main PC with it.
