Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

Hi there @macnb

On my Z390 i9 9900KS iMP build, would it be better to spoof the CPU and/or the mobo?

FWIW, I had the paid version of VideoProc. It doesn't actually use the GPU, it just pretends to. I had a back and forth with the company and they admitted that AMD and MacOS isn't supported. They gave me a refund after a month of email flurry.

He does NOT prove that the changes he make to SMBIOS to MacPro7,1 ACTUALLY made any difference.
He does NOT show that his system can encode AND decode BOTH h.264 AND HEVC.
He does NOT show that any CPU loads NOR GPU loads for various Apps that he has (videoproc, FCPX, Adobe Premier, etc).
He does NOT show BEFORE and AFTER "benchmarks".

All these Apps use the CPU and GPU differently - especially FCPX (which works differently between different versions of ITSELF even on real Mac's).

You have to try it yourself and prove to yourself it works using repeatable/verifiable tests.

I tried the recommendations in the video and ran some tests. So far, the older version of Final Cut 10.4.6 still renders considerably faster than the new one.

The changes made in 10.4.8 seem to break hardware acceleration causing H265 to render painful slow and also double the render time for H264.

Here's a basic test:

A 1:30 1080p video was rendered using the 'Apple Devices 1080p' and the 'Apple Device 4K 8bit HEVC' standard presets. Here's the results:

FCPX 10.4.6
1080p render time = 30 seconds
4K 8bit HEVC render time = 28 seconds

FCPX 10.4.8
1080p render time = 1:10
4K 8bit HEVC render time = 4:15

Hi guys,

I tried to go through the thread but still confused.
I successfully installed Catalina 10.15.4 with Clover on my Dell XPS 8500 with i7-3770, MSI Radeon RX570 8GB.
As I understand i7-3770 has Intel graphics HD 4000. In the BIOS I set Enable Multi-Display support to Enabled. That's the only graphics related option it has. No memory for iGPU, nothing else.

System does not recognize iGPU. And when I run Davinci Resolve 16 rendering it does not utilize Radeon GPU (On Windows it does).
Is there a way to enable hardware acceleration?

Thanks in advance.

Not sure about spoofing CPU or the need to do that.
There are plenty of folks here with a 9900KS cpu.
You have set your model id to iMacPro1,1.
That system does NOT have an IGPU.

My aging 3770K does have an IGPU BUT I turn it off in the BIOS and use iMacPro1,1.
That's is the only way I can get FCPX (10.4.6) to use the RX580 for encode and decode oh H.264 & HEVC.

VideoProc is a strange one. I get it to work even though it says "Graphics N/A":

It actually works pretty well in using the RX580 in transcoding H.264 to HEVC and HEVC to H.264.

See these :

Regarding your config, it's looks like you are NOT using Whatevergreen.kext.
I now use it. It takes care of a lot of issues - Black Screen patch, correct number of video ports, ACPI renaming (GFX0,IGPU,etc), GPU power management just to name a few. If you had an IGPU, it takes of connector-less framebuffers, etc.
Can't tell from your config if you have turned off your IGPU but you may want to try that with iMacPro1,1 model-id you are using.

You have a great CPU so may wish to consider using iMac19,1 that closely matches your system and the IGPU of that CPU is pretty decent for H.264 & HEVC encode/decode too.

Great tests.
I too did similar tests and agree with your findings.

FCPX 10.4.8 and Compressor 4.4.6 are a REGRESSION as far as AMD GPU GPU's are concerned (I think VII fares better).
I have gone back to 10.4.6

Looks like your first post.

Don't know much about XPS 8500 but you should be able to Enable/Disable the IGPU.
Ideally you should be able to make the PCIe / External graphics card (i.e. your AMD GPU) Primary.

I disable IGPU.
I use SMBIOS model ID of iMacPro1,1
I use Whatevergreen.kext

I have not tried Davinci but I know it works well with AMD GPU on macOS. If your GPU is not setup properly, then it may not be able to use it.

Thank you. I used your method and everything is fine.
What are these widgets you have on desktop?

You're welcome.
They are Apps.
One is Intel power Gadget (free from Intel).
The other is iStat Pro (paid for). I had to use FakeSMC v6 kext and it's sensors kexts for this as VirtualSMC does not quite work.

VideoProc is a strange one. I get it to work even though it says "Graphics N/A":
View attachment 465466

I also do get "Graphics N/A" when using WEG + Lilu(AMDFrameBufferVIB is used) only. But when injecting Orinoco FrameBuffer + WEG, VideoProc does display correct GPU Name. I don't see much of difference in GeekBench 4 score between these two method which is around 14.5k~14.6. But it does show difference in GPU power consumption reading in HWMonitorSMC2 which decreased from 90w to 30 when Orinoco FB is used.

Thx for the info.
I do not see any real difference between the WEG-only & WEG+Inject Orinoco method. The inject method has a couple of negative side effects: not all the ports work in the order I expect (DP vs HDMI) and you get an extra port that's not functional and I want DP as the first port.
