Update: Apple's leadership has confirmed the importance of RAM on Apple Intelligence compatibility, among other factors.
While the unveiling of Apple Intelligence has been met with positive feedback from the majority of users, some have been disappointed at the lack of support for most iPhones. Currently, the only models that will support Apple Intelligence are the iPhone 15 Pro and the iPhone 15 Pro Max.
For reference, the computing power of the M1 chip is around 11 TOPS, while the A16 chip runs around 17 TOPS. Meanwhile, the iPhone 15’s A16 chip has 6GB of DRAM, compared to the 8GB in the M1 chip and the A17 Pro chip found in the iPhone 15 Pro and iPhone 15 Pro Max.
As such, we can speculate that Apple Intelligence must require around 2GB of spare memory to function, which is an issue considering Apple’s general lack of on-device DRAM for its phones.
While it is common to see Android phones with DRAM options as high as 16GB, and even as high as 24GB (that'd be the recent Asus ROG Phone 8 Pro), Apple has offered fewer DRAM options in their devices, with most not exceeding 6GB. However, we will likely start to see this change and there are rumors that the iPhone 16 will have higher DRAM across the board, which is more likely considering this 2GB requirement to use Apple Intelligence.
There is the obvious argument that Apple has deliberately levied this 2GB requirement to push consumers into upgrading their phones. However, another mindset is that Apple has focused on offering the best product it can, and with that comes certain limitations. We'll know for sure over the next few months as we start to dig further into Apple Intelligence.
