A good resource for this information is http://mactracker.ca which is an app that has a huge database of all Apple devices ever made, detailed specs, max official (and unofficial) upgrades, and max supported OS version. 

I realize your catch-22 of needing an Apple device to look up your first Apple device you don’t yet own. So, here are screenshots of the iPhone XR record. It supports the latest iOS, so it should be pretty capable of pretty much anything. https://i.nostr.build/8GMXB.jpg https://i.nostr.build/lLwQB.jpg https://i.nostr.build/WG0Me.jpg https://i.nostr.build/Q76n7.jpg https://i.nostr.build/6GqvR.jpg https://i.nostr.build/BRzde.jpg https://i.nostr.build/oMOPQ.jpg https://i.nostr.build/AaoGM.jpg https://i.nostr.build/nWVlg.jpg
