Given how much better AMD CPUs are these days, I was wondering what the downsides to using them for hackintoshing are (beyond needing to patch the kernel of course) and how likely the situation is to change going forward.
As far as I'm aware there are three main downsides:
- No CPU power management. Does this mean that the CPU is always running at 100% frequency, even at idle, and putting out as much heat as if it were fully loaded? Or does the firmware take over regulating frequency based on load (in Intel terms, like speed shift vs the old OS-controlled P-states?)
- Is hypervisor framework still not working? AMD CPUs also have hardware support for virtualization (AMD-V), what I'm not clear about is whether AMD-V is the same x86 instructions as VT-X with a different name for marketing or if they are actually different. On the Windows side of things, Hyper-V works with either.
- No QuickSync hardware: can macOS use the video encoder block in AMD discrete GPUs instead? (guessing it can, otherwise trashcan Mac Pro and iMac pro would be cut off from stuff like SideCar). Does AMD encoder block behave better under macOS than it does on Windows (encoding quality being noticeably worse than QuickSync and NVENC - check conclusions section at end of page)?
