I already am planning to upgrade my 12.9 Pro to have a Cellular model again, but I'm holding for the M2 lest Apple screws me over twice a la A12Z not getting most of the upcoming iPadOS 16 features on a 2-year old chip.
Side Note:
The A12Z chip is only 2 years old. It came out in 2020. The A12X chip came out in 2018. They are not the exact same chip, not matter how many people claim otherwise.
Yes but the A12Z Is based directly off the 4 generations old A12. The single core and neural engine is the same as the standard A12 chip. It’s still powerful for sure, but based on 4 year old architecture.
