The M1 chip’s AI computing power can handle 11 trillion operations per second (TOPS) while the A16 AP can perform up to 17 TOPS. This means that AI capabilities between the chips is not the issue. Kuo says that DRAM memory is the differentiator. The amount of DRAM on the iPhone 15 and iPhone 15 Plus is 6GB which is lower than the 8GB of DRAM found on the M1. More importantly, not only is 8GB of RAM used on the latter chip, it is also used on the A17 Pro SoC that powers the iPhone 15 Pro and iPhone 15 Pro Max.
As a result, the iPhone 15 and iPhone 15 Plus does not get Apple Intelligence while the iPhone 15 Pro and iPhone 15 Pro Max do. We hate to keep rubbing this in, but we are only the messenger (and I do own the iPhone 15 Pro Max. Sorry!).
Kuo says that the iPhone 15 non-Pro models won’t support AI because they are equipped with only 6GB of DRAM
With these figures, Kuo says that Apple Intelligence on-device AI LLM (Large Language Model) requires about 2GB or less of DRAM. LLM is used by AI platforms to recognize and generate text. The analyst says that Apple Intelligence uses a 3 billion parameter LLM and he writes “After compression (using a mixed 2-bit and 4-bit configuration), approximately 0.7-1.5GB of DRAM needs to be reserved at any time to run the Apple Intelligence on-device LLM.”
Kuo adds, “Microsoft believes the key specification for an AI PC is 40 TOPS of computing power. However, for Apple, integrated with cloud AI (Private Cloud Compute), 11 TOPS of on-device computing power is sufficient to start providing on-device AI applications.” He also notes that in the future, Apple will move to a 7B LLM for Apple Intelligence which will require iPhone models to have even more DRAM in the future. The question, as Kuo notes, is whether Apple will use the DRAM requirement to continue to differentiate between non-Pro and Pro iPhone models. It would be a way for Apple to generate more revenue from iPhone buyers.
The analyst does state, “Whether the user experience is as good as Apple claims still needs to be observed. Samsung S24’s AI capabilities are limited, and Microsoft’s AI PC still confuses consumers. Apple has successfully defined on-device AI (at least consumers are already aware of the rich AI features and selling points of Apple’s AI devices), which will accelerate competitors’ imitation and catch-up, thereby driving rapid growth in the on-device AI-related industries.”
