I mean honestly the only reason I would stay with Mac would be the 4 TB3 ports, the heat and performance of MacOS pales in comparison to their Windows software production counterparts.
I will say I consistently get better benchmark scores on CPU in macOS than Windows, but anything that involves the GPU is hilariously poor on macOS compared to Windows.
What do you do that solely depends on the CPU and would improve so much by moving to AMD, at the cost of a completely different OS and software?
It would still be beleaguered by Windows, the main reason most of us moved to Macs. :)
