Obviously ARM haven't done so in all these years and have no public plans which is an answer in and of itself, however currently they have:
I get why they wouldn't want to, another set of cores on top of already strained resources plus you can have 2-4 lower clocked A7_ cores instead which makes all of that pointless anyway. But the tech enthusiast in me wants it just because
Spec scores, power & efficiency calcs:
Int scores & total power, A715/A510 ((3.64 points/1.03)/(5062 Joules/4698))=3.28x efficiency
FP scores & total power, A715/A510 ((5.7 points/1.14)/(4093 Joules/3994))=4.88x efficiency
- X_ series - highest performance "big" cores which split from the A7x a few years ago, laptop potential. X1, X2, X3
- A7_ series - now the PPA efficiency "medium" cores, A78, A710, A715
- A5_ series - very small & low cost, area efficient, low absolute power, In-order "small" cores, A53, A55, A510 (that's 3 gens from ~2014-2023)
