You can use the Radeon Enterprise drivers with gaming cards, but they lack the workstation certifications and features.

They are also not intended for BootCamp.

FWIW... Navi was funded by Sony and Microsoft. If it's silicon is geared towards gaming, there is a good $$$ reason for it.

Remember, Apple funded Vega... Go figure it performs well for what Apple wanted. Now, Navi Drivers OS support is immature. Until Microsoft smooths out their approach to working with Navi architecture, or someone unlocks the driverd potentially hidden in MacOs, will the true compute and gaming performance of Navi come to fruition.

If Radeon VII gets discontinued because of poor sales, I hope AMD will make a Frontier version.

It seems Frontier users kept their cards because VII is not prosumer.

One user guide is now available from AMD for both RX 5700 and RX 5700 XT:
https://www.amd.com/system/files/documents/radeon-rx-5700-series-quick-start-guide-en.pdf

The system requirements state:

"Minimum 600W (recommended 700W) PSU with up to an 8-pin + 6-pin PCI Express Auxiliary connectors. This PSU recommendation is only for one Radeon RX 5700 series GPU installed per system. Additional GPUs will require more capable power supplies."

"Windows® 10 or Linux® operating system (64-bit operating system is highly recommended)."

View attachment 847717

Looks like waiting for modified lower power requirement versions from individual vendors would be the best plan, or else supplement with external PSU or internal "hack" or modification of some kind. Still likely best to use an Apple recommended RX 580 for the vast majority of MP5,1 users.

Just FYI, cMP has ~1000W PSU.

I found these FP64 specs:

Vega II: 1:4
Navi: 1:16
Vega: 1:16
Polaris: 1:16
RTX: 1:32
GTX 10: 1:32

I have found errors in that database before, so I would not be surprised if Navi is actually 1:32.
It looks like Navi is indeed 1:16, but the cards have less compute power than Vega 56 stock (Edition just a little bit more).

Maybe that explains why they are called 5700 and not 5800.

They would still be better than TITAN RTX and RTX 8000 at FP64.

Compute benchmarks on the RX5700 are mixed. Falling slightly behind the RX580 in some benchmarks, and having great gains in others. While the RX 5700XT has better performance than the RX580 across the board, as to be expected, it uses a bit more power than the RX 5700.

At it's core, NAVI is power friendly consumer oriented chipset that will most likely find it's way into multiple Apple devices in the future. Whether there is support hidden in Mojave that requires KEXT modifications to unlock is still TBD.

Thanks for sharing. :cool: If XFX is calling out mac compatibility and they are including a 8-pin to 6-pin power converter, they may have inside info on MacOS compatibility.
[doublepost=1563142691][/doublepost]I bought the card blindly, running in a Razer core x, the card is not recognized by either Mojave or Catalina, although in system report it does show up as an AMD card but not able to run anything off this card, so disappointed in AMD

Why are you disappointed with AMD if it is Apple who makes the drivers?

you may need to modify the amd6000 kext with the pcie identifier from the card.. this step was necessary to enable the rx480 and radeon vii early before apple enabled it by default.

If Radeon VII gets discontinued because of poor sales, I hope AMD will make a Frontier version.

Limited dies availability is more likely than poor sales. Apple's upcoming Vega II models use exactly the same die as the Radeon VII. If Apple put in a large order for Vega II then there may not be ay 7nm die starts left for the Vega II. Remember also that AMD is trying to pump out as many Ryzen 3000 and RX 7000 all on the same relatively fixed number of 7nm wafer starts they have access to. AMD is probably also probably trying to build up inventor on x86 chiplets for the growing EYPC order they have too. Threadripper is also substantively delayed from entering the market.

Throw on top that Apple is also probably also bought out a humongous block of 7nm wafer starts over the next several months for their huge demand bubble in Fall. AMD's ability to show up and say "I'd like to buy more wafer starts" is probably at zero for a while ( or just about anyone else).

So it probably isn't not because of "poor sales" as much as poor profits for AMD to allocate any 7nm wafer to Radeon VII at this point. It likely never was a profitable product to begin with, but they probably had a large block of 7nm wafer starts queued with no volume products to absorb them. AMD has exactly the opposite problem now.

It makes about zero sense for AMD to allocating 7nm wafer starts to a product that could be making close to zero net profit for them when they have others that do. "Starved out" may be more accurate than ''discontinued'. ( the latter is a bit dependent upon just how late the "big"/HBM Navi is going to be . )

If Apple has completely blown their forecast then some starts could open up again (after slams on the brakes on its orders, Again AMD may find gaps of starts needing product to match. ), but if Apple is close to be right about demand then AMD will be ecstatic to sell those dies into Vega II instances at a profit rather than just "fill the demand gap" with the Radeon VII.

There is a secondary side effect if Apple is "buying up" all the excess "Vega 20" dies that folks won't be able to as easily by-pass the Vega II with a third party Radeon VII.
[doublepost=1563213738][/doublepost]
It seems your timing is right on target... Looks like the VII is discontinued.

Some other article mentioned "end of production" which I think is a probably a better description.

"... AMD Radeon VII is no longer in production. ..."
https://videocardz.com/newz/amd-radeon-vii-reaches-end-of-life

"end of life" and "discontinued" sound more so like they are abandoning the cards which they probably are not. Right now they aren't making any more. There are inventories out there. And depending upon how the follow on products go then there are other contexts where that basic die will still be deployed for next year or so.


P.S. this seems somewhat indicative that while substantially higher than the Radeon VII price point ($700), Apple won't be trying to put the Vega II well over the $2K price point. That Apple intends to sell a decent number of these.

Sure, it is also very expensive and not gaming.
Not that expensive....

And it games just fine....

Navi supports 8K VP9 decode up to 24fps. There are 60fps videos on youtube.

this one looks fun

so in resolve the card is fast.
looks like it can encode 6 4K60fps streams at once on the GPU

but looks like on windows the drivers are bugy as hell at the mo

To those like myself - 70 years old soon with diminishing eyesight .. . 8k 60fps won't make much difference to my current 1080 24" .. I was born too early. I can't imaging what will be standard, cheap & available in 2030 but I possibly will be drooling my dotage away or worse. . . :) . . maybe I can pry my pumped up Amiga 4000T out of the arms of a friend I gave it to.

im just happy to see GPU's actualy doing things, how long have we used video apps and seen almost no GPU utlisation!


it was cube talking about 8K not me, just saw that video and it's intresting to see it's punching past it's price point in video work but still looks like drivers are relay bugy.

It looks like for more people it would be better to choose CAS over 8K@60Hz VP9 decode.

CAS?

I think the only people looking at 8K video at the moment are TV makers seeking new markets and video camera manufacturers.

for me the cmp CPU is maxed out, so the only real gains in video editing can be gained from GPU and software that can actually use that GPU to accelerate work.

We are finally seeing some real steps forward with the https://forums.macrumors.com/threads/activate-amd-hardware-acceleration.2180095/

So maybe in a year when the GPU drivers are in osx and editing 1080p/4K video may see real gains in speed.

and as nice as CUDA/nvidia is unless apple changes there not an option.
