Max Memory ArcGis Pro can use?

Question

I have 32gb of ram on my current system and AGP only seems to use about 11gb of it.  I am wondering how much ram AGP could potentially use.  People say to get 64gb of ram for AGP but if it can only us 11-15gb why do you need so much surplus?  I realize the surplus allows you to run other programs while geooprocessing but still 64 would seem like excess.

Thanks,

Well, as definitive proof of Pro's capability to use a lot of RAM, here is the result of some custom Python scripting in ArcPy that accesses a gigantic 172 M record database table and extracts data for each record.

More than 80 GB work memory usage, 24 GB residing in actual physical RAM (laptop with 32 GB RAM).

Do you also say that knowing the result of those 500+ layers is this?... 😉

Anytime I see someone with > 500 layers in a Pro TOC, I generally think they don't know how to properly use the application.
