Apple Explains Why Apple Intelligence Exclusivity on iPhone 15 Pro Isn't a 'Cash Grab'
Why won't older iPhones receive the upcoming AI features?

Older iPhones won't receive the upcoming AI features because their computational capabilities are insufficient to handle the demands of AI processing3. Apple's AI chief, John Giannandrea, explained that while the AI models could theoretically run on older devices, they would be too slow to be useful3. The iPhone 15 Pro and Pro Max have the necessary hardware, including more RAM and a larger Neural Engine, to support the AI features.
What makes the A17 Bionic chip superior to the A16 Bionic chip?

The A17 Bionic chip is superior to the A16 Bionic chip due to its 3nm process, increased transistor count (19 billion), faster CPU cores, and an additional GPU core. It offers a 10% improvement in CPU speed, 20% faster graphics performance, and twice the neural engine performance, enabling more advanced machine learning tasks.
What is "Apple Intelligence" as mentioned in the news?
