hi Sup Forums
have any of you ever tried using an eGPU? i want to use one for video editing when i am on the go. the x220 has a shit display, but it's all I have to work with. sony vegas isn't too bad to work with, but the render times take fucking forever.
>i5 2540m
anyhow, I know it can be done with the x220 via expresscard. any experiences? tips?

eGPU? Enlighten me
tried using egpu with the express card slot.
very hard to find a card that will work with it.
not sure how you would go with USB 3.0 version of it though
There are plenty of tutorials for Thinkpads. It's very doable
Does video editing really eat into the GPU though? I know it can take a shitload of ram but I thought the decoding/reencoding was mostly a CPU based thing without custom hardwares.
CUDA for nvidia and OpenCL for amd
I did the external GPU thing for a little while it worked all right I think for your uses it will probably work better then what I was using it for
What was your set up?
It doesn't use the GPU at all except for effects added to the video that are actually rendered on the card. Like 3D effects and transitions, for example. Unless you are using said effects that are specifically designed to be rendered on the card, a GPU will make absolutely no difference except speed up the playback a little bit while doing general editing, because CUDA and OpenCL do not actually encode the video. They just render the effect to the project and then it is encoded by the CPU.
Now you CAN however use plugins like the homemade NVENC plugin for Adobe Premiere which uses the built-in H.264 encoder on GTX 600+ cards (also Quadros and some GTs) to encode the video, cutting off a noticeable amount of encode time.
If your editor does not support this though, a GPU will make no difference in encode time. Just render time.
It works very well for video editing (insofar as video editing benefits from a GPU in the first place). The main bottlenecks for gaming use aren't relevant for this application, so it works about as well as it would in a desktop.
Okay cool I still don't actually know what goes on under the hood of a lot of the effects I use but since it's mostly libre shit I imagine very little GPU-wise.
If anyone was wondering this is the easiest way to enter the comfy eGPU terrain
But does that support ExpressCard Gen2? Is it stable? I've heard nothing but complaints about EXP GDC.
eGPUs are a bit of a gimmick. If you want decent video editing get a fucking desktop with a proper big screen. What you're considering makes no sense.
And the CPU+fast drive are way more important than the GPU for video editing.

find what you need and google the model number
how
I've bought two and literally nothing bad happened and I'm not sure
I didn't ask for this but thank you so much user kun I've been needing some of this shit
No problems here with my T430 and GTX 670. Pretty much plug ang play.
Have you checked if it runs at gen 2 speeds though? My PE4C does and I've not had one single issue.
What's your experience been like? How does it compare bandwidth/performance wise etc? I've been looking into it and that looks like the best option I've seen so far, thunderbolt stuff is still fucking expensive.
Yep. GPU-Z reports Gen2 speeds too.
Both expresscard and mpcie are like 4gb/s transfer speed capped. Your best bet nowadays is a thunderbolt3 adapter, than expresscard,, than mpcie, than m.2
Also its not just videocards, you can do pcie sound cards and make a decent recording station or tv tuner/htpc
Sorry, 4gb/s with expresscard/mpcie. Thunderbolt runs at like 8gb/s
How is it for gaming on the x220? I have a spare GTX460.
Has anyone tried it on Arch?
It's working pretty well on Arch for me, especially since they've recently enabled GLVND in Mesa (which means that you can finally have more than 1 libgl installed at the same time)
