    Isn't that roughly the performance loss for Thunderbolt 2? I thought TB2 was ~15% for external monitor, but I could be wrong

     

    Maybe, the bandwidth itself is not a big problem here while using eGPU.

    IMO, the real problem lies in the cost of converting protocols between TB and PCIe, as well as the lack of a direct route to CPU instead of a separate controller bypassing the chipset.

     

    Based upon this benchmark: https://www.techpowerup.com/reviews/NVIDIA/GTX_980_PCI-Express_Scaling/21.html

    PCIe x4 3.0 has a efficiency of over 95% comparing to PCIe 3.0 x16, anything lower would be extra cost then.

    Are these the overall scores or just the "graphics score" part of the benchmark?
    You wrote GPU score, but just to make sure.

     

    Also, huge thanks for the values, my Thunder3 comes on Monday and I'll post
    benchmarks with my XPS 15. But if I look at people with a Thunder3 case, it seems
    like the performance between the Node and the Thunder3 are is the same.

     

    Yes they are the "graphics score" parts.

    Hi !

    Does this mean i should wait before buying all the stuff to make an eGPU ?

    I need a good GPU when i'm at home and a laptop for the school...

     

    I don't know your performance need so I don't have a answer.

    Actually the performance hit using external monitor (10% ~ 15%) is acceptable to me.

     

    Maybe next year when Intel integrates TB3 controller into their CPU the efficiency would be over 90%, but that's a small increase.

    Fire Strike Extreme GPU score:

    Midtower @ PCIe 3.0 x16 - 6482/100%

    NUC with PE4C V4.1 @ PCIe 3.0 x4 - 6016/92.81%

    NUC with Akitio Node output by eGPU @ PCIe 3.0 x4 - 5707/88.04%

    NUC with Akitio Node output by iGPU @ PCIe 3.0 x4 - 3890/60.01%

     

    wow a loss of up to 40% of power over TB3  that is terrible, and I expect since its not in the CPU directly but its in trough the  Intel Alpine Ridge thunderbolt controller that this will mean lattencies, so from what you show, eGPU is quile below GPU. 

     

    The 40% loss happens when I connect the monitor to the miniDP port on the NUC, so it's normal to have much worse performance than output by GTX 1060 directly.

    The actual loss over TB3 is 10% to 15%.

    Where did you buy the Node from ?

    I am surprised by the benchmark. Maybe I do not read the values right but the Node seems to have a greater performance hit over TB3 than the PE4C ! I was expecting similar values.

    What do you mean by eGPU and iGPU ?

     

    In China, Akitio started pre-order on Nov 11th, and shipped on Nov 23rd.

    TB3 performs worse than PE4C because the latter connect the card directly to the PCIe interface,

    while the former has to pass through Intel Alpine Ridge thunderbolt controller.

    This situation will be better since Intel is going to integrate thunbderbolt 3 directly in the CPU instead of using a separate chip.

     

    eGPU means the monitor is connected to the GTX 1060 in Node, while iGPU means it is connected to the miniDP port on NUC.

    It's like using internal screen or external monitor while using laptops.

  6. Got mine today, hands-on with benchmarks later.

     

    Package and size comparison with a 9.7' iPad Pro:

     

    y3mTT_z1EUMbBZVDUkaBJABuSmG67akKhf56Bx4A

     

    y3mat_6_MXDaAAZRC3g67ko8eN_S2ETETe726jL7

     

    y3m-tTDSwMqP011705bXLPqMRVUVoilCz0reeUhU

     

    Standard Akitio front face, TB3 port and a PSU with a separate switch, which is nice since the PSU fan would continue spinning if you leave the power cable connected.

     

    y3m1L4ZynhFqKQu2lX-WPK1lCv37lt2WYybQvvhh

     

    y3mXaPV7M6FUgP16ksulRK7MrbuH19wXmjIHqUkk

     

    Internal

     

    y3mXp-A1zKr3M9qZTm6rv2MYKeO2VI2_fiFA9lVb

     

    2pin connectors for power LED and front fan, which means the latter would not adjust speed.

    After first boot, I decided to pull it out to switch the fan off to eliminate the noise.

     

    y3mKGz7KCnmyIwoZYK0Mp7mhXvQ3n5FDlEZl65JY

     

    Design flaw, the 6pin connector to power the TB3-PCIe board would conflict with those cards with thick backplates.

    You would have to push the card a little bit to properly install the screws.

    The card is a MSI GAMING X GTX 1060 6GB.

     

    y3mNoK5WXfuU4mGHB0YL8YnUSUhPRaQTsWijYnRf

     

    Card installed and the space left is considerable, a water-cooling radiator is definitely possible.

     

    y3mo143eQhf6Jop032EqLj7dlrcRo7VV5KB9F_GF

     

    TB3 cable is 50cm long made by Akitio.

    I ordered a Belkin 2m 40Gbps cable and it works perfectly.

     

    y3mvC6IOKWE_1UAPRhS9aZPv_qPrKG07AZ42p05R

     

    The front fan comes with a tool-free mount and it blows out air by default, which is good for those dual or triple fan cards.

     

    y3m4R4cGD0RMqE3xwxj5crOZLgfkrvhGTBbg3SJq

     

    PSU is a customized model and unfortunately, it does not come from any major suppliers.

     

    y3mF6flLcqDrAROsX-RCebnfC6VIFandJTcvufDN

     

    PSU fan is too noisy so I just switch it off by unplugging the connector.

    IMO fanless would not be a problem for a 400W PSU while delivering 120W.

    I fear that with the incompatibility of the new MBP, the node will delayed even if other would be customers are ready to buy it right now.

    I hope to be wrong but I do not believe it will be available before Xmas :(

     

    In China, we've already pre-ordered Node on Nov/11, estimated shipping date is late November.

     

    But it's another story in EU since you are in France.

    They are moving their production line from Shanghai to Taiwan, and increasing the price to cover costs.

    I contacted them last week for PE4C V4.1 since I'm in Mainland China and their shipping cost is too high through official shop.

    A week passed without any reply and I have to call their Taipei headquarter about purchasing.

    Then the news came that they have just increased the price. :frantics:

     

    So instead I bought the last PE4C V4.1 on Mfactors, but have to wait much longer before delivery.
