Apple Intelligence compatibility — here’s why older iPhones won’t work

technology June 13, 2024No Comments

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.

Since Apple revealed its AI strategy at the WWDC 2024 keynote this week, there’s been fair speculation on why this is. Now, Apple analyst Ming-Chi Kuo has outlined his thoughts.

In a report posted to Medium, Kuo goes into an explanation between the A16 Bionic chip inside the iPhone 15 and the M1 chip present in iPads dating back to 2021. While the iPhone 15 from late-2023 can’t run Apple Intelligence, the three-year old iPad Pro can, and it’s less to do with overall computing power, known as TOPS, as it is about memory.

Kuo states the obvious distinction between the two is the on-device DRAM (dynamic random access memory) — that’s the key part.

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.
