Hi everyone , would this work on Vega VII?
I ran it after wake upThat's pretty normal for an RX580.
There's no more that can be squeezed out from that card.
Did you run the benchmark straight after booting or after waking from ?
On my Z77X-UP5 + RX580 Nitro+ running Mojave (10.14.6) I get similar scores to you.
But, on Catalina (10.15.4), if I run the benchmark after booting, I get ~ 40% LESS and only get those "normal" scores AFTER waking from sleep.
Reporting no change in GB scores after implementing your EFI and disabling iGPU in BIOS. Attaching the new ioreg as requested. Hope we can find the culprit...
Edit: Btw., lost Sidecar. I can "connect", but there is a black screen shown on the iPad...
Yes it is safe. Why is on compute?
I have a 5700XT and my max GeekBench 5 is 40K Metal after this mod, Can you share your efi folder to compare?With Geekbench 5 my 5700XT went from 38k to 65k in Metal and 38k to 60k in OpenCL.
This is not affecting the Luxmark results and I think because its an old benchmark tool anyway, nor Engine Heaven but all good.
Thanks for sharing
Thanks for sharing,just to share my benchmark:

Enable again IGPU in bios for sidecar.
Hi mattystonnie, thank you for your support and your hard work!Introduction
A couple of weeks ago I got my hands on a new Navi GPU, The Sapphire RX 5500 XT 4 GB, everything was working but the performance was not there, everyone said it is on pair with the good old RX 580.
So I got my hands on the new macbook pro 16.1,mac pro 7.1, and looking into the ssdt, dsdt and ioreg I saw what was missing from my hackintosh machine.
With a few tweaks and frambuffer injection, the performance went up especially with metal apps, low power consumption too.
The RX 5700 XT SSDT.aml works with RX 5600/5700/5700XT.
The RX 5500 XT SSDT.aml works with RX 5500/5500XT.
This method tries to mimic a real working mac.
How to install
Right now I am using Open Core Bootloader, but it works with clover too.
There are 2 methods for this to work, same methods are used by Apple : SSDT.aml for headless installation or Property Injection method for advanced users ( just copy the things from the SSDT.aml and add into the Property Injection section).
For VEGA 56/64 and RX 580 do not use rename PEGP to EGP0.
Clover method
- First thing to do is to download the SSDT.aml file corresponding to your GPU and drag&drop into /Volumes/EFI/EFI/CLOVER/ACPI/patched
- Second thing to do is to download WhateverGreen and place it into /Volumes/EFI/EFI/CLOVER/kexts/Other -- this will fix the video ports
- Download the dummy kext dAGPM (made by @toleda) that will help with power management for the GPU and place it into /Volumes/EFI/EFI/CLOVER/kexts/Other
- Edit the Clover Config file from /Volumes/EFI/EFI/CLOVER and add this DSDT renaming : rename PEGP to EGP0 find : 50454750 replace : 45475030 also add boot args : agdpmod=pikera (fix black screen on some gpus, mine works without).View attachment 464763
Open Core method
- Download the SSDT.aml file corresponding to your GPU and drag&drop into /Volumes/EFI /EFI/OC/ACPI
- Second thing to do is to download WhateverGreen and place it into /Volumes/EFI /EFI/OC/Kexts
- Download the dummy kext dAGPM (made by @toleda) that will help with power management for the GPU and place it into /Volumes/EFI /EFI/OC/Kexts
- Edit the OC config file from /Volumes/EFI /EFI/OC and add this patch renaming TableSignature SSDT find: 50454750 replace : 45475030 comment: replace : 45475030 ---- also add boot args : agdpmod=pikera (fix black screen on some gpus, mine works without)

5. Add the SSDT.aml file and whatevegreen kext and dAGPM kext into the config file and enable it .

Conclusion
As you can see in the pictures the performance improve very much, in open gl test there is no improvement, only in open cl and metal, sometimes after opening many apps the score went very high. The open cl score did match the one from Windows 10.
The best performance was achieved using SMBios iMac Pro 1.1, DRM works on all video output ports.
