Current overview (not historical)

AI overview

The base model of Apple's M4 iPad Pro (256GB and 512GB) ships with 12GB of physical memory hardware, but only 8GB is made available to the system, with the remaining 4GB reportedly left idle. This discrepancy was confirmed by teardown analysis identifying two 48Gbit Micron memory chips. The practice contradicts Apple's official marketing, which states the base model has 8GB of memory, and has been interpreted as an apparent barrier to AI feature availability.

    Apple M4 iPad Pro base model ships with 12GB memory but limits usable RAM to 8GB for tiered pricing

    Report first recorded Nov 2, 12:55

    The base 8GB model of the M4 iPad Pro uses memory chips with a combined capacity of 12GB, but Apple restricts the usable RAM to 8GB. This restriction maintains the price gap between the 8GB and 16GB configurations, as upgrading to 16GB requires purchasing a 1TB or 2TB storage model. The limitation affects access to advanced Apple Intelligence features in iPadOS 27, which require at least 12GB of unified memory, leaving 8GB iPad Pro users excluded despite the hardware capacity.
