AMD Radeon Performance Enhanced SSDT

@mattystonnie Thanks very much! My RX 5700XTs OpenCL score went hugely up with your SSDT!
Geekbench 5: Before 59150, after 68572! Thats does +16%! :eek::)
 
In MacOS:
Geekbench 4 OpenCL: 145681
Geekbench 4 Metal: 146932
Geekbench 5 OpenCL: 41360
Geekbench 5 Metal: 48521

In Windows:
Geekbench 4 OpenCL: 138155
Geekbench 4 OpenCL: 145185 (OverClocked: cClock 1500 MHz, mClock 2250 MHz)
Geekbench 5 OpenCL: 48332
Geekbench 5 OpenCL: 50729 (OverClocked: cClock 1500 MHz, mClock 2250 MHz)

I ran few trials on each and have posted the best results.

What version of macOS are you running ?
 
Hey, I've been reading this thread for a while and tried all of the versions of SSDT for my Vega 64 (its an MSI Airboost Varient) The SSDTS are definitely being applied, but I can't get my geek bench scores to break 52000ish. Any help would be greatly appreciated.

EDIT - IOREG AND EFI ATTACHED

I have applied the SSDT for my Vega 56, it works fine with VegaTab_56.kext. However, I also noticed the device names that show in Hackintool are not correct.

Please see the screensnap, there are two devices show as '???', which I believe they belong to my Vega56.
Screen Shot 2020-04-29 at 4.57.07 PM.png

The device paths are:
PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)
PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)

And the IOReg IONames are:
IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/PEG0@1/IOPP/PEGP@0
IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/PEG0@1/IOPP/PEGP@0/IOPP/VEGA@0

I didn't apply any name changing patches.

Not I. jus using WEG + Orinoco FB


Running on 10.14.6
That's interesting.

On my system (i7-3770K + RX580 as iMacPro1,1 booting either 10.14.6 or 10.15.4),
I get the following Geekbench 5 scores:

10.14.6: 42891 (OpenCL), 41631 (Metal)

BUT, with

10.15.4: 26539 (OpenCL), 26738 (Metal) => almost 40% LESS on Catalina !!!

Something is wrong with 10.15.4 on my system o_O

Same system, different results on different OS's.
 
nop, no ssdt or anything that can boost performance

Catalina, 10.15.4 + sup upd
What SMBIOS model-ID are you using ?
