hi just want to ask what support for the RX 470 is like now, there relay cheep on ebay uk compared to the RX 480/5xx cards. (tho id gess 90% have been mining 24/7 
so 50/50 they are going be half melted)
is the card well supported? and any brand work better or not well? (sapphire/MSI?)
im mostly interested in davinci resolve use (then games), been getting some crashes in osx when my GTX770 runs out of vram (4gb) and hoping for a speed up too

Nope. Ran it again with similar results. Not sure why I'm seeing such a low score.
Admittedly this is by no means a clean install. I upgraded HS and each DP along the way so perhaps that's it.
Or maybe having all four DIMM slots populated could also be impacting performance. Not sure.

AMD unveiled the new Vega 56 based Radeon Pro WX 8200 with 8GB of "Gen 2" HBM2. The memory clock runs at 2.0 Gbps rather than 1.89 Gbps on all other Vega cards (total memory bandwidth is 512 GB/s vs. 483.84 GB/s), so according to anandtech.com there will be cases where it's faster than the WX 9100. With a retail price of $999 it will be quite the bargain compared to the WX 9100 ($2199 msrp). We could see the price go lower than that too since the WX 9100 often sells for $1500. It's likely the device ID is 6868 so it should be compatible in macOS. Available for preorder tomorrow.

Did you monitor the GPU parameter in terminal during test?
Code:
ioreg -l |grep \"PerformanceStatistics\" | cut -d '{' -f 2 | tr '|' ',' | tr -d '}' | tr ',' '\n'|grep 'Temp\|Fan'I wonder if your RX580 was thermal limiting.
No it’s not. It’s the same price. I would definitely pick the WX 8200 over the FE. Higher memory bandwidth + ECC, higher binned chip, up to 10 year warranty vs 1, lower power, lower temperatures. It may have the fan issue like the FE though unless Apple fixes that.

Maximum it went to while running Luxmark. Presumably if the fan speed isn't going higher it's not throttling? Seems like there is plenty of headroom.
"Fan Speed(%)"=38
"Fan Speed(RPM)"=1634
"Temperature(C)"=73
That's about the same as my Pulse 56. Max temp running LuxMark was 70 °C, with fans at 1647 rpm. But then the fans continued to go higher just after the benchmark to 1842 rpm max (42 °C) and then leveled off to 1650 rpm as the temp dropped to 30 °C. It started out at 0 rpm at 40 °C. I had to open an HEVC video to make the fans stop spinning. Running latest beta 18A365a so Apple hasn't fixed it.
No point in arguing but the VEGA FEs are dirt cheap on eBAY right now (and discontinued). They are highly binned parts which can easily run at only 950mV as opposed to the default 1200mV. You can also clock the HBM2 at 1050Mhz. And you get an extra 8GB of memory. Of course without ECC (which is a show-stopper for some). The warranty is depending on which part of Earth you inhabit.
I am quite sure no way to downvolt the Vega in MacOS.
AFAIK, the only way to downvolt a GPU in MacOS is via VBIOS mod. But the Vega’s ROM is signed (locked).
The entire string (soft table) from regedit in Windows can be pasted into the appropriate kext.
Thanks for the info. That sounds about right to me.
May I know when you run keep Unigine Heaven running (Extreme preset, so, default to window mode for easier GPU monitoring in MacOS), will the GPU temperature rise above the pretermined target temperature? (75C for Sapphire PULSE RX580 8GB). And the fan still locked at 60% (around 2200RPM)
Any details how to do it? I never see any software way to mod the GPU clock / voltage in MacOS.
Extract the string in Windows should be the easy part, but inject that into the appropriate kext correctly seems can be quite challenging.
Also, is there any confirmation about the kext mod actually works? When I mod my Sapphire PULSE RX580. The VBIOS can actaully ignore any “invalid” value in the 1st loop (what we modded) and using the 2nd loop value (default voltage).
I know it’s more like a Sapphire thing than AMD thing. But I wonder if the kext mod does really have effect.

At the end you should see <key>aty_properties</key>, inside the <dict></dict> brackets insert your custom soft power table.
Add your soft power table there, like this (this is for VEGA RX 64 and FE):
That should give you Core: 1442MHz/1075mV, Memory: 1045MHz/1075mV, SOC: 1199MHz, Temp target: 70C, Idle fan: 700 RPM.
Have in mind your Windows soft power table is separated by commas and slashes, whereas MacOS doesn't use it, so strip that from the key. Can't remember if they are in Base64 or hex but it should be apparent.
This is at your own risk!
You can verify core and memory clock speed with IORegistryExplorer, look in AMDRadeonX5000_AMDVega10GraphicsAccelerator -> PerformanceStatistics

You could also use this app to generate a Kext for you.

I don’t think modifying the kext is a good idea. That’s hackintosh stuff. SIP would have to be disabled for it to load and it still might not load so the Mac either wouldn’t boot or you’d be met with a black screen.
It's not like this is a new thing. People are already hacking away at the firmware and whatnot. The old Mac Pro is on life support.
The failure risk is too high in my opinion. Yep, and some people who modified their firmware bricked their Mac even when they thought they knew what they were doing. It’s great Apple is still supporting the classic Mac Pro. It’s better than ever.
Surprising thing just happened for the Vega FE. It is QUIET for the first time.
"Fan Speed(%)"=19 (usually at 40%)
"Fan Speed(RPM)"=976 (Usually around 2000)
"Temperature(C)"=80 (it's hotter than usual, makes me worried)
What's going? I haven't installed or updated anything.

You posted in the new firmware thread that you updated the firmware and using the latest beta. Perhaps the new firmware fixed it?
No. i don’t know. I updated the firmware 3 days ago. The quiet fan happened today.
In any case, the Vega got really hot, and I rebooted. The fan went back to full blast again at 2000 rpm. Can’t replicate the low rpm.
Have you tried playing an HEVC video? This one works for me when my fans spin up: http://4ksamples.com/elysium-2013-2160p-1-minute-sample-footage/
Thanks, that works. Playing HEVC with IINA the fan spins down to 760 rpm. The temp steady in the 40s.
I tested 3 different data rate HEVC clips on IINA and they all worked. The fan speed stayed low as long as the IINA player was open, even when switching on the fly to a H264 clip, play or pause it.
I tested two HEVC clips on QT Player. Only one clip worked, play or pause, and only if QT is restarted. It didn't work switching clips when QT is open.
This is curious, but not practical. Probably a bug. As soon as I quit IINA, the fan spins up again.
Booted up the Mac this morning and the Vega FE didn't spin up. The fan stays quiet at 880 rpm without IINA playing. The temp climbs up to 70s.
Looping 4K video clip in QT Player, and the fan ramps up to a constant 1400 rpm. Quit QT and the fan spins down back down to 850. The temp at 77.
Playing 4K Youtube on Chrome. The fan goes up to 1400.
Rendering a 30 sec 4K clip to ProRes in FCPX, the fan spins up to 1600, the temp at 80. After rending, the fan down to 844, temp stays at 80.
Cinebench 4D, fan 2002, temp 84.
Unigine Heaven, fan tops 2000, temp 84.
For the apps above, after quitting the fan spins down to 700-800 every time. But temp doesn't go down, it stays hot 75-80.
Now HEVC on IINA...fan 1200-1600, temp 70s. However, the fan does NOT spin down after quitting. It spins up to and stays at 1900, temp up & constant at 84.
UPDATE:
Shut off and rebooted 30 minutes later, Vega FE back to "normal"...
"Fan Speed(%)"=40
"Fan Speed(RPM)"=2002
"Temperature(C)"=37
Anyone else experience this with your Polaris or Vega GPU? Have you sent in a feedback to Apple? I'm tempted to submit a feedback but does Apple care about the Vega FE/64?

Wouldn’t hurt to submit a bug report from the developer website. Apple lists the FE on their eGPU page and they’ve been directing people to that page for a metal capable GPU for the Mac Pro. So if they don’t want us to use Vega they haven’t made that abundantly clear.
