eGPU docks? (programming.dev)

Hi all,

Just wondering how progress is on eGPU docks? I want to upgrade my GPU at some point and thought it might be cool to put it in a dock and connect it to a laptop. The laptop has a couple thunderbolt ports.

How's compatibility these days?

Makes me wonder if this is a possible future. Just get a small nuc like computer and connect it to an egpu.

    It definitely is, but likely comes with a slight performance sacrifice due to bus speeds.

    It’s more than slight! I ran a 3090 in an eGPU for a while and it lost around 40% of performance compared to when it was in my case.

    That can depend on a lot of factors, though. From the bus of the enclosure to the speed of the USB port and cables you used.

    I wouldn't have expected a 40 percent drop on the modern USB standards, but I'd still expect a drop. I was thinking closer to 20 percent.

    For sure. It's something I've considered for a while simply because I don't need that extra heat/noise created by the GPU when I'm only doing my day job.

    My only problem with this is that the docks are like $300. I guess igpus are getting good enough that I’ll probably never need a dgpu again.

    Still surprised how well the steamdeck can handle resident evil 4 remake.

    I really don’t need better graphics than that. In fact, they don’t even need to be that good.

    I went down this path, but mini itx nucs with a GPU slot seemed to be better as long as you're not using the egpu on multiple devices; if you are, then it might be worth considering just making a PC a host and running sunshine/moonlight. While I haven't tried connecting to my host on the steamdeck, I have on my laptop and felt like it could be used for gaming
