yeah but there isn’t much newer threads to respond


oh really.. I knew the non x chips always used high performance but I always thought the X series chips prior to A10X always used high efficiency and I swear I’ve seen posts around saying similar things
Just to clarify here: The X series chips prior to A10X chips had high performance chips and high efficiency chips. In usage, apps and the OS can choose if they'd use performance or efficiency chips. After A10X chips (I believe A11 marked the start) all chips can be used together, so an app can make use of all performance and efficiency chips together, simultaneously. Adds up for a small boost here and there.

Nope. The A10X was the first to feature high performance and high efficiency cores. These cores were homogeneous (so only cores of the same type can be used at the same time).

Before the A10X, the Apple SoCs only had one type of core. By necessity, pretty much just best performance at the time of release.

now that with version 17 of the two OS’s

1. A11 iPhones aren’t getting it
2 A9X iPads aren’t getting it

SoDespite A10X iPads getting it and the A10X iPads being the oldest to support iOS/iPadOS 17 ( like the A8X from iPadOS 13-15) and with Apple dropping 7 iPhones this and last year

Good chance Apple may extend this iPad till iPadOS 18 alongside the 2 A10 iPads and the A12 iPhones ( with this strategy)

Yep A10X is the new A8X for sure
Since you woke up this old thread, I'll give you my predictions, yes A10x might get iPadOS 18 but not both A10 iPads, only the 3GB RAM one, for the reasons I explain in this thread https://forums.macrumors.com/threads/predictions-for-ipados-updates-over-the-next-8-years.2391411/
Still A10x won't probably be the longest lasting iPad chips, A12X/Z and M1/M2 will probably have an even longer life...

There are plenty of calculators for iPadOS, including one built into Spotlight.

Yup and like every other time that argument gets dragged out, feature parity on my core devices is an essential part of ease of use and the ecosystem proposition.

I’m not gonna evade on one platform to a totally different tool that’s either ad ridden or a complete outlier from a design perspective.
