I can't imagine wanting to play a AAA game on a phone, but that sounds really impressive. Qualcomm has been dormant for a while. They also had a great opportunity to break into the laptop space with Windows' ARM support getting very good, but they're still doing nothing...
It's easy to not notice the march of time, but it's good to remember that these are all games built for ps4, which is decade old hardware at this point. So this is about expected for the latest mobile hardware.
To be honest, technology isn't the main factor to be amazed with but the fact that we are going to get such AAA games even when iOS nor Android are the market for it, you know, they are no Candy Crush or any regular gatcha game...
I don't even have an iPhone anymore, but even if I did I wouldn't get those titles there, I will never forget Apple (or Epic or whoever fault is) to turn their back to Infinity Blade games, the third one even was a tech demo with an iPhone presentation FFS! (Does that ring a bell BTW?), and so many other good AAA like games have been lost in the time, especially with iOS.
It would be amazing if it went well and smartphones were finally taken seriously because they have so much unused potential for videogames. I know the A17 Pro should be perfectly capable of running these games in theory, but with the crap cooling of the iPhone we'll have to see
