Nice result!

This guide has worked well for my RX570! Back in the Mojave days, I'd get GeekBench 5 Metal score of 43k. However, with Catalina and Big Sur, I was getting 27k. Now with the tweaks, I'm getting 44k. Nice!
Though, I still have a concern... It appears the idle power consumption is still high at ~65Watts. I can confirm the Orinoco framebuffer is in use. I thought that would lower idle power. Any suggestions?

With my Sapphire 5500 XT Nitro+ it went up 10k+ on Metal. OpenCL remained the same.

Thanks for the very interesting work... I just tried out the SSDT for RX580, and got the following results (before and after sleep)...

Before SSDT:

Metal:

After SSDT:

So overall, a very mediocre increase in performance... but GPU die temp has come down anywhere from 5c to 10c, which is a real achievement!

Hope someone finds this info useful. PS. Using iMacPro1,1 SMBIOS without agdpmod=pikera, Sapphire Pulse RX 580 8GB

I have same card. Can you share your picture of tablesignature part? I'm not sure did right that part. Below is mine and is that right?
