What spec states 8GB is best?

Are you running Pro Tools First and forgetting to tell us? The current recommended minimum system spec for Pro Tools is 16 GB of memory, with 32 GB or more recommended... the transition to 64 bits and Avid stuffing the old girl with multiple components of Java and whatever else bloatware has not been kind to her figure.

16 GB of memory in current Arm based Macs is a severe restriction, but it ain't the only one.

Why do you think current Pro Tools will run at all on Big Sur even on an Intel powered Mac? (it might in 2020.11). Even if it runs on Big Sur on Intel why do you think it will run at all on an Arm powered Mac on Big Sur? And if it runs at all why do you think it will be stable enough running on top of a translation layer? In only 16 GB memory (minus memory used by the GPU).

We might know a lot more in days to weeks, months?? It might be more than a year until Pro Tools and major plugins are running reliably on Arm based macs... nobody really knows today. And not many people will care until Macs with more than 16 GB are released.

And now repeat all those questions for your Audio interface vendor about their driver and other software.

And now repeat all those questions for Superior Drummer... which you really ought to be asking Toontracks about.
