Would really appreciate if anyone can help me figure out what I'm doing wrong with my Airboost Vega64, IOREG and EFI posted on page 30.

TIA!

@mattystonnie Fantastic work. Can’t wait until if/when you get the time for Radeon VII.

Fingers crossed for good progression on the RX 580 etc.

Early SSDT for the rx 580, works best with Catalina, for Mojave I don't know.

My Sapphire Nitro RX 480 8GB has a clock of 1276 Mhz, so RX 580 should get a higher score.

How to install : use the SSDT into Clover/acpi/patched + WEG.

Also test after a sleep/ wake cycle, for me worked without.

For the second stage boot loading bar use the first display port of your GPU.

More good things are coming, trying to inject properties from the Radeon Pro 580.
Thanks for your efforts. Will try it later.

For GB4, I'm getting 143312 (OpenCL), and 136900 (Metal) using iMac19,1 model ID out-of-the-box.
See my updated numbers here.

Thank you for posting this and thank you for your hard work! I disassembled your RX580 SSDT and see that you call DTGP. For those of us not using DTGP, I assume we need to add the Clover DTGP patch or edit your SSDT to eliminate DTGP.

I ran with and without the new RX580 SSDT and don't see much difference. Could this be because I have Clover graphics options enabled (config.plist) as described below?

My GeekBench 5 test results with and without Radeon SSDT v1.0 are as follows:

Without SSDT
  • Metal: 49930
  • OpenCL: 45057

With SSDT
  • Metal: 51914
  • OpenCL: 45188

My system is as follows:
  • Socket 1156 / H55 / Xeon X3460 / 16GB DDR3-1600
  • SMBIOS MacModel: MacPro5,1
  • Sapphire Pulse RX580 4GB
  • Clover (Legacy) r5115 (boot-arg: -no_compat_check)
  • Catalina 10.15.4
  • Lilu 1.4.3, WEG 1.3.8
My CLOVER r5115 graphics config is as follows:
  • FB Name: Orinoco
  • Vendor ID: 0x1002
  • Product ID: 0x67DF
  • Inject ATI
  • RadeonDeinit

On Mojave 10.4.6 & RX590 get a black screen
