If you’re looking for gaming go with the a12x/z. Better workstation a14.

Nope Workstation=A12x bionic(more cores and better multi-core power) Gaming =A14 bionic (better cpu power , better ram and supports latest updates on GPU) But who uses a chipset for workstation purposes lol

All in all, what you can do and how they perform is very similar and within the tasks you throw at both of them, they will both deal with them with ease. The two biggest difference between these two devices would be that one uses face ID (2018) and the other uses finger print scanning and one is 120hz and the other is only 60hz. If you are thinking of buying an ipad, I would strongly recommend you to go with the ipad 2018. I know some people might not feel very comfortable with buying a device that is already 2 years old over one that just came out in 2020 but the 120hz is too good to give up. Also, if you are someone that wants to buy an ipad to had write alot. The ipad 2018 seems like the best device for you.

Um no That doesn’t mean that the performance will be much better also A14 is more power efficient
