In recent years, Apple has vigorously advanced its strategy of self-developing chips, evolving from the A-series and M-series processors to the Apple 16e, released earlier this year, which debuted the company’s first proprietary 5G modem, the C1. This effort has now expanded with the introduction of the N1 wireless networking chip and the upgraded C1X 5G modem in the iPhone Air. These innovations not only allow Apple to exert greater control over hardware performance and energy efficiency but also establish the technological foundation for future “Apple Intelligence” services and on-device AI integration.
In a recent interview, Tim Millet, Vice President of Platform Architecture, and Arun Mathias, Vice President of Wireless Technologies, emphasized that with the integration of the N1 wireless chip and the enhanced C1X 5G modem in the iPhone Air, Apple has achieved deeper mastery over the operational behavior of its devices.
“That’s where the magic is. When we have control, we are able to do things beyond what we can do by buying a merchant silicon part,” Millet remarked, linking this philosophy to Apple’s acquisition of Intel’s wireless business in 2019—a decisive move to gradually free itself from dependence on Qualcomm.
Nevertheless, the iPhone 17 and iPhone 17 Pro series continue to rely on Qualcomm’s Snapdragon X80 5G modem, the same chip found in the Snapdragon 8 Elite, suggesting that Apple has not, as speculated, introduced its in-house modems into mainstream models—likely to avoid compromising the user experience on its flagship devices.
According to Mathias, the new C1X modem not only delivers twice the speed of the C1 used in the iPhone 16e but also reduces power consumption by 30% compared to Qualcomm’s previous generation. By designing its own wireless chips, Apple can integrate Wi-Fi-based location services more efficiently, allowing devices to perform positioning tasks without frequently waking the main processor, thereby conserving energy and extending battery life.
While the iPhone 17 lineup remains tied to Qualcomm’s technology, the adoption of Apple’s C1X and N1 chips in the iPhone Air highlights the company’s deliberate strategy of gradually testing the waters with core components, tightening its grip over critical hardware.
Beyond connectivity, the evolution of the A19 Pro processor stands as the central highlight of Apple’s latest devices. Millet revealed that Apple has not only strengthened the Neural Engine but also integrated the neural accelerators directly into the GPU cores. This architectural shift accelerates machine learning and AI inference tasks, enabling performance levels comparable to those of a MacBook Pro.
Apple, Millet stressed, is building “the industry’s best on-device AI capabilities,” with equal focus on privacy, security, responsiveness, and efficiency. The new GPU architecture enables seamless switching between traditional 3D rendering commands and neural network computations, effectively transforming the iPhone into a new category of “programmable computer.” This means future iPhones will be capable of handling gaming graphics and AI workloads side by side, even running advanced generative AI functions entirely on-device.
Although “Apple Intelligence” has yet to deliver the fully conversational experience of platforms like ChatGPT, Apple’s broad advancements in custom chips—spanning communications, graphics, and neural computing—make it clear that the company has already laid the hardware foundation for the next chapter of AI competition.
