    Moving to a laptop shortly with tb4 and only has a single port.
    Given that I'll be guaranteed bandwidth, would a TB4 dock and a full speed downstream port really affect performance?

    40gbps throughput for gpu, network, peripherals and external storage should be decent enough I'd think....

    That's what Intel's marketing claims is possible but I guess it should work as advertised.

    $600 for a dock is a bit rich so ill probably just direct connect and run the rest of my stuff via a usb 3.0 port dock

    That probably makes more sense. The only time I've seen TB4 used for its higher speeds is when video editors directly connect to a TB4 capable NAS with 4-8 HDD's or even SSD's if they can afford it and then edit directly off the NAS.

    I will be running a usbc DAS so would be nice but the laptop only has a single TB port
    The dock would be ideal but too expensive currently for my taste

    i have a 3080ti running through TB4 and it gets the same frame rates as PCI cards

    have a few 3080s and 3070s as well in TB3

    to get those speeds you need a proper thunderbolt 3 cable though - USB-C cable will not cut it

    Thunderbolt cables arent all that cheap, expect $20+ for a short 0.7m on ebay

    Any updates?

    I'm heading down the egpu road as well. AMD Ryzen 6000 series supports USB 4, so my next laptop will make this possible.

    Scrapped the idea and returned the laptop, went back to a desktop.

    Note that EGPU's need Thunderbolt, not just USB4 for connectivity

    USB4 has/is TB3 from what I understand.
