Thank you for your comment!
I am interested in this topic, could you elaborate?
It should. I've tried the Gigabyte AORUS Radeon™ RX580 8G XTR and that card works great.
In my experience, the RX460 (which works OOTB with Sierra in cMP) does NOT work with High Sierra beta 1 thru 3. The Windowserver crashes at the last stage loading the gfx divers, leaving the boot progress bar with an endless spinner about 10 mm from completion. A Safe boot gets past this but then no accelerated graphics. Has anyone found a way past this?
[doublepost=1500075842][/doublepost]Sorry to say this but I think you are wrong. In my actual experience, with High Sierra beta 1 thru 3 the presence of the RX460 as a secondary card stops the boot with a Windowserver crash even when a stock Apple GPU card (5770 or 5870) is present.
So proceed with caution if you are relying on this. I think it is a Metal 2 bug that will get fixed but right now it is a show stopper for non-Apple GPUs.

The RX 580 below is the best, without a shadow of a doubt.
This specific card is the one included in Apple's eGPU dev kit and for which they have made the edits for already. This model correctly displays in About this Mac. It also uses native macOS drivers from 10.12.6 onwards. No need to download any drivers or hack .kext files. It just works out of the box.
SAPPHIRE Pulse Radeon RX 580 8G GDDR5 Dual HDMI/DVI-D/Dual DP Graphics Card - Black
See here for details: #470
They do, and usually I would get a reference/FE model. However, in this case you don't want to do that, you want to get the EXACT model specified above.
Why does it matter which 580 I get? I am just about ready to call it quits with my cMP if I now need to get a specific model from a specific manufacturer.
He was just saying that because:
Other Rx 580 should work because they share the same device id. Just won't get the same information displayed in About this Mac. It will be more generic info.

If someone uploads the firmware from the Sapphire we can adapt the info section to other firmwares. Hypothetically it should work because we aren't touching anything except one line.
But if Apple is serious about supporting graphic cards again then macOS should read graphics card info just like Linux and Windows does. We should report it as a bug until they do.

I'm still waiting for response if Devil Box will be 100% plug and play with High Sierra or if Mantiz Venus has an international warranty.
Doubt it. There hasn't been significant jump since last year and generally macOS drivers remain flatlined forever without further optimisations.
The important thing you should protest and make feedback reports about is the lack of HEVC 4K decoding on the GPU. It's available in Windows, it's available even in the Radeon Boot Camp drivers, but the Mac drivers for Polaris don't include it.
This means in High Sierra you will have zero chance of playing HEVC content on a cMP and even a Skylake will struggle. In Windows all good.
The blame for this should be placed directly on that useless Craig Federighi who turned macOS into the most technologically backward mainstream OS on the market with its crap drivers and old APIs. Even the most boring Linux has better graphics support.
Playing HEVC content is not a problem at all, of course, not for super high bit rate HEVC video. But IINA can play reasonable bitrate 4k HEVC content nicely on a cMP. It's been discussed in another thread just few weeks ago.
No hardware HEVC decode is a matter, cannot play HEVC content is another matter.
But I totally agree that Apple should provide support about HEVC hardware decode in MacOS.
Yeah. We have been testing these videos on the other boards. They are 4K 60FPS 10bit. If a Mac can't play these back then a video editor or content creator is handicapped. They can't play their render output.

The Polaris GPUs can decode them easily in Windows. Even a crappy dual core Skylake Pentium can do software decode in Windows with 25% CPU usage.
In High Sierra, still no GPU decode, Kabylake hardware decode isn't perfect, Skylake software decode is terrible.
