Hello,

I have a Aspire 15 A15-41M-R7ZM (NX.KXAEG.001) and was wondering if the USB4 Port supports Thunderbolt?

And if it does which Version of Thunderbolt?

I am asking as I plan to buy a Dock and would like to know if I should by a simple USB-C Dock or a Thunderbolt (3,4 or 5) Dock? And also if in theory it would support an eGPU-Dock.

Hope someone has any knowledge or experience in that regard.

Thanks in advance

    I dont see that your laptop has thunderbolt, because the laptop has a symbol on it.

    Below is the specs for your laptop

    Thanks for the info, but please instead of a screenshot provide a link to the source because after searching some more I found the following:

    https://www.acer.com/at-de/support/product-support/A15-41M/NX.KXAEG.001/details

    As you can see it has a USB4 port, but it does not provide further infos what linkspeed it supports one 3rd-party site says it has 40Gbps:

    https://laptopmedia.com/review/acer-aspire-15-a15-41m-review-surprisingly-good/

    The claim that the port supports 40Gbps is also supported by the specs provided by AMD:

    https://www.amd.com/en/products/processors/laptop/ryzen/8000-series/amd-ryzen-5-8640hs.html

    However I found no indication that it supports Thunderbolt, maybe I'll just buy a TB-Dock and try it and if it does not support it just send it back.

    Anyway it is somewhat disappointing that Acer does not provide more detailed infos of the capabilities of the USB4 port, as the USB4 port designation alone just keeps you in the dark about what features of USB4 are supported.

    OK, after some trial and error here are my results:

    First in Windows there is limited reporting regarding Thunderbolt, I only found 1 place in settings where it shows the link speed is 40GBps,
    see below screenshot:

    In Linux there are way more commands to analyze the capabilities of TB, so here are some screenshots and explanations:

    In the following screenshot we see pretty much the same as in Windows that the dock is correctly identified and that we have 40GBps link speed:

    In the next screenshot we see the in Thunderbolt controller name: Advanced Micro Devices, Inc. [AMD] Pink Sardine USB4/Thunderbolt NHI controller
    Which is good to know that the internal identification shows that it is in fact a USB4/TB controller, so it should in fact support the capabilities of Thunderbolt 3 if not also 4.

    Personally I just bought an old HP Thunderbolt G2 dock, for 50€, and it is supported and works without issues I would guess that other TB3 docks should also work without issue, but YMMV.
    I did not yet have time and the resources to test a TB4 dock or an eGPU, but some others reported in other forums that this controller should be able to handle an eGPU albeit with some issues as mentioned in this forum thread:

    I just hope that this will help other in the future and that manufacturers more clearly state what features there USB4 implemenation suuport.😑
