Does ARM Cortex-A55 being on ARMv8.2-A hold back big cores in any way?
 

So after Apple announced the x86->ARM transition I compared 64-bit ARM cores and one thing stood out. Most cores are on ARMv8.2-A, but Apple has updated their revision every year since 2016 and are now on 8.4 (so A14/A14X will probably be on 8.5). My question would be if there are any big advances with revisions after 8.2 and if it's possible to match a 8.2 A55 to, say, 8.5 A79?
