m4f1050 Posted September 4, 2018 Share Posted September 4, 2018 (edited) Can I use an RX 580 or better (if better, which one is the best one I can use as of today?) for video pass-thru? I have latest unRAID. Edited September 4, 2018 by m4f1050 Quote Link to comment
Jcloud Posted September 4, 2018 Share Posted September 4, 2018 I think, so long as the video card supports UEFI it's usable for video pass-thru. Quote Link to comment
testdasi Posted September 5, 2018 Share Posted September 5, 2018 I think the best way to gauge is to just search your intended card model on the forum and see if anyone reports problems / any success stories. Quote Link to comment
tbonedude420 Posted September 11, 2018 Share Posted September 11, 2018 This issue is more related to IOMMU groups rather then the GPU itself. As long as you've got separate iommu groups, you should be able to pass 'any' gpu though to a host. Drivers are installed on the host as well. IOMMU groups are more dependent on the motherboard, not the peripherals attached to it. The issue I see (at least as your signiture indicates) is the older amd 8350. Most any newer card(gpu) will be bottlenecked by this cpu. Even the top dog of the socket 939/940 world (the amd 9590) is bottlenecked.. even at 5ghz. The issue isnt one of frequency, but instructions per cycle, also known as IPC. Quote Link to comment

Just talk to the LT guys about Linus' 7-gamer-1-PC project and all the issues they had to work around. 😓 Simplest way is really just to search the forum for your card and see if other people have had success with it. Ability to pass through doesn't mean your quality of life using it passed through is gonna be great. 😂 Quote Link to comment

This is good information though, and yes its best to just search the forums here. That being said, the cpu is still a bottleneck in this case. And you loose give or take 10% due to overhead anyway, so YMMV. Quote Link to comment
