Yeah, this is all beyond my pay grade. Hence why I ended talking about Real World performance. It’s rare in comparison articles that they look at a system holistically and I’m sure that MacOS has a lot of optimisations under the hood to deal with their own hardware as it is so limited in terms of hardware variation. Linux and Windows on the other hand have to account for a plethora of hardware combinations to deal with. Performance can even vary greatly depending on cooling systems, equipment environment and optimal operating temperatures. The liquid immersive cooling data centres are insane and allow the hardware to run way faster than traditional cooling. You are certainly right when you say it is a complex topic.
In the end, if it works for your use case then it works for your use case. There are still pros and cons for Linux vs Mac for a Flame system but gone are the days when a Linux system could render the same setup in half the time of a similar spec Mac.
