@OliverB :Is there anybody in the eGPU community doing numeric calculations/simulations? I don't think so. 80% is gaming, the other 20% doing some Movie/Imaging stuff. Double precision being superfluous."

Do you think this will change as they enhance the drivers? Are you saying this is not a great card for gaming and video processing (my interest being the latter)?  Thanks.

@screendor not too sure for FCP X and PPro/AE (my testing with FCP X yields very little benefits), but Davinci Resolve seems to have tremendous gains with the Radeon VII, as seen in a review by Puget Systems. This is for Windows though.

Basically in Resolve, for any editing that is more than basic level, the Radeon VII is faster than the 2080Ti, and significantly faster than the 2080.

edit: turns out they did testing for Adobe software too with the Radeon VII - Nvidia is still king for Adobe.

If you are an Adobe user in Windows, an Nvidia gpu still makes more sense. I suspect this is why Blackmagic touts their egpu solutions as made for their software - adobe uses Nvidia, fcp x barely saturates an rx580, and only resolve starts taxing the Radeon VII.

Thanks for the update @kelvin_tan.   So it seems as if I may have purchased a doorstep--unless something changes with the drivers and/or FCPX is tweaked to take full advantage of it.  Time will tell.  Hopefully at the June WWDC and OS 10.15—and a new update of FCPX, thing improve...

@Kelvin_tan I tested Resolve vs Adobe AME: XAVC, ProRes and H.264 are all faster using AME to render ProRes Proxies. Resolve only pulled ahead with XAVC-I from FS7.

Each used the GPU to almost 100% except for H.264 which only hit about 60%.

You could make the argument that Resolve has better GPU utilization (I'm not sure it does) but for my tests, actual speed trumps technical utilization and I'm gonna stick to Adobe AME unless I'm specifically in need of a bunch of proxies from an FS7 and in a super hurry. Otherwise I prefer AME's front-facing workflow rather than the import/export nature of Resolve.

@arden_shibley I'm not making any arguments haha. Just passing around found benchmarks while waiting for the Radeon VII to solve it's whirring fan issue.

As a professional video editor(?), I'm sure you are in a better position to advise compared to me a mere hobbyist in this. Good to see AME utilising the GPU to it's max in ingesting and convert!

@defoler thanks for the reply! Yes, thats what I was trying to do. I watched a video on 9t05 where he set it up that way and it was working. its weird, if I use displayport from the LG to my Caldigit TS2, the monitor and mac seem to work and I don't get the displayport message. its just when I go from the razer core x to the LG. Do i need to be downloading any drivers for the core, lg or V11 before connect?

I've done a fair bit of testing in FCPX and it's interesting to see how NLEs use the hardware in different ways.

In Final Cut, decoding long GOP or IPB footage (XAVC, H.264, etc.) or R3D footage is more CPU intensive but barely touches the GPU. ProRes or All-I codecs require drive performance. It's only when adding GPU-accelerated plugins (stylized looks, distortions, etc.) and transcoding/exporting that the GPU gets stressed beyond whatever is needed to drive displays and general UI responsiveness.

I haven't been able to play with any 360º footage yet, but I'd image that hits the GPU somewhat as well.

@robin_Martin .  Yes, that mirrors my experience.  When the new modular Mac Pro launches (at WWDC methinks), I imagine FCPX will be tweaked to take better advantage of eGPUs--since that's likely to be how the GPU is configured.  Will they?  Dunno.  Will they optimize for Radeon VII (in addition to other currently "approved" eGPUs like the 580 and Vega 64)?  Dunno.  Hope so.  Big time.

100% I’m really hoping WWDC gives us a clearer idea of where Apple is headed.

@defoler would it be worth a try to purchase a usb c - displayport 1.2 adapter or just send the monitor back and get something else???

Do you have a link to where they have used the LG UL display?
From what I have seen, they used the 5K2K, which is a different display, that does support displayport.

I'm not sure usbc-DP adapter will work. Maybe you can find someone on this forums that have been able to make it work, I don't know. But as far as I know, the LG monitors that are sold on the apple site, are not DP compatible for display directly. You can daisy chain from it, and the Caldigit TS2 also output TB (not just DP), but directly from GPU to the LG, I'm not sure it will work.
