Apple always make their A chips as a one time release using the fabrication of that time. Eg an A15 will always be 5nm, even when there are newer chips with 4nm.

In comparison, in the Android world, Qualcomm, Mediatek, etc have chips with older cores (A78, A76, or even A73) but fabbed with newer fabrication (eg from originally 12nm to newer 6nm). Thus they have chips for lower end phones that are using old cores but not hugely deficient in efficiency.

Should Apple do the same? We already see Apple using an "older" chip on a new phone (ie A15 on iPhone 14). So seems like Apple is open to reusing their previous gen chips. Apple chips are all flagship class, so even if we have A17, the A15/16 cores are still well performing, and wouldn't it be nice if they are made with the new node as well?

Or would this expose Apple's "gain" in performance was simply due to smaller nodes? Eg Apple wouldn't be able to show better jump from A16 to A17 from marketing perspective if both are on 4nm.
 
That is extra layer of complication - using the old node is safe option since you order packages of cpu and store them until you are ready to slap it into new budget iphone and at some point to base ipad (hello A12).
 
It isn´t that easy, you have to adapt the chip design to the manufacturing node, you cannot use a 5nm design and fabricate it in 3nm...

Apple have done this before. The A5 used in the 3rd Gen Apple came in three versions: initial versions for the iPad 2 and iPhone 4s were 45 nm and later versions for the iPad Mini, iPod Touch and Apple TV were 32 nm.
