Technically, you can run an AMD CPU using Hackintosh (though the spelling is a bit off), but for a native experience, stick with Intel.
TofuHaroto, agree; I'm focusing on optimizing all components for better performance. Almost everything is set, just need to finalize RAM quantity and rate. The 2019 iMac supports up to 128GB with 32GB DDR4 per stick, but it runs at 2666 MHz. I'll keep researching to confirm concrete options. If not, I'll consider: i) 32GB 2933MHz DDR4 CL14 targeting 128GB; ii) 16GB 3600MHz DDR with a maximum of 64GB.
It varies, but you're not likely to see a big boost—maybe around 10% at most.
TofuHaroto, the 10th gen uses DDR4-2933 MHz as its base speed; I didn’t notice that before.
