If you have a complicated enough project, Davinci will happy eat all the hardware you can throw at it (well, up to 3-4 GPUs at least). Puget Systems of course wants to recommend you buy the most expensive thing they can convince you to buy from them.

DaVinci's own hardware requirements listing are considerably tamer. For Mac users, they want 8GB ram minimum and a Metal or OpenCL GPU. Reportedly it works really well on entry level M1 Mac Minis. 2 versions ago worked pretty well on my 2012 Mac Mini with 16GB RAM, and supposedly newer versions run better. I've also run it on Windows with Intel graphics and it worked (not great but it worked), and on a Windows PC with an 2014 mid range GPU works extremely well for HD projects.

It isn't hard to picture them being able to tune it down to use less RAM, especially considering that that removed Fusion from the iPad version which is the most RAM intensive part of the program.

I'm not sure how well I will like using it from touch, but since the basic version for iPadOS will be free, I'll be tempted to try it on my iPad Air.
