Wasn't the basis of AMD naming the the Vega's 56/64 due to the compute units? Maybe they'll follow that path again.
Got a tip for us?

Just trying to sell my FE then I'll pick up a VII and test it for you all 
I really just want the Mac Pro to have the same swing door design that the Quicksilver/Power Mac G4 had. The handles should be cylindrical though. The handles on Power Mac G3/G4 and Mac Pro were very uncomfortable to grab.
I think that handle is a part of the security function, make sure it will cut someone's hand if they try to steal my cMP

Haha...you might be right. When I bought my first Power Mac G4 I unboxed it at work and then tried to carry it home. Was very painful and will never be forgotten
Any news upon correct identification of PowerColor RX 590 Red Devil in 10.14.5 beta? Got mine today, identifies as Radeon Polaris 8GB and in System Monitor as RX Ellesmere Prototype.
Works fine so far, 5-10% more output than RX 580, but fans spinning loud!

Just wanted to thanks everyone here for the work done and sharing the knowledge, it helps me to get ride of my Nvidia!
After one failure, with a Nitro+ Limited edition (don't ask me why? I was certainly drunk when I order this card) I found a nice second hand MSI Air Boost 56.
Plug & Play nothing else to do except few work around to fix the speed fan using VGtab and Kext utility.
The card is silence and I manage to leverage the same power installation I had with my previous GXT 980ti.
No more driver issue!

Yeah Apple hasn't added identification of the RX 590 to the driver. You might be able to edit the bios to make it think it's a RX 580 Pulse with one of the Mac version numbers.
I take it as a no then.
is that I would like to take a used pulse rx580 but that has the Orinoco frame buffer and not the AMD frame but I don't know how to know it before.
In case it has the AMD buffer can you change it via software right?
I think you misunderstood something.
The framebuffer is not stored on the card, but assigned by the OS.
The card itself won't has Orinoco framebuffer or RadeonFramebuffer.
In Windows, the driver will always able to detect the card's hardware correctly and assign the correct framebuffer (assume the users haven't mess around the ROM, system, etc).
In macOS, only two specific ROM image part number will be detected correctly, and assign Orinoco framebuffer correctly by the OS. For all other part number, macOS will assign RadeonFrameBuffer for it.
You can't check if that card "contain" Orinoco framebuffer in Windows (or any other OS).
I wrote down the whole procedure here about how to change the ROM's part number, and make macOS able to assign Orinoco framebuffer for the PULSE RX580 8GB card (do NOT do this on ANY other card).

Why not? If @MacManu77 dump the GPU rom with GPU-Z/etc then open it with any hex editor, he will see the product ID and then will know if the card has one of the two Orinoco IDs.
Thank you, will you give me more info please? What do I get if Gpu's got the buffer Orinoco?
Thank you for your contribution, I did not actually understand the operation.

Thanks, I'll have them checked and we ll see if we can read.
I am using reference Vega 56 card with Nitro+ second BIOS to remove the fan issue. Is it possible to declock Nitro+ BIOS GPU frequency?
There is no need in additional 2-5% speed, but looking for less noise and heating.

But I don't understand why.... If Sapphire Radeon Pulse RX580 is an Apple's reference card, why isn't assigned correctly Orinoco's buffer?
Make sure you directly send Apple feedback if you want Orinoco for all Sapphire Pulse RX580 8GB's:
https://www.apple.com/feedback/mac-pro.html
This should be something that could be achieved relatively easily by adding additional GPU ID's to the "list".

hi guys.
As i know asus rx590 has only one 8pin connector, did anyone try this gpu with mac pro 5.1? Will it work?

Is there any difference in functionality ? With Orinoco framebuffer in macos and without? Or it is only the lable in "about this mac" difference?
