Apple just achieved total control over every core chip in the iPhone lineup, introducing neural accelerators directly into GPU cores with the A19 Pro while debuting its first wireless chip and second-gen modem. The move signals Apple's most aggressive push yet to make iPhones the dominant AI platform, potentially reshaping the entire mobile chip ecosystem within two years.
Apple just pulled off the most significant chip strategy shift in iPhone history. The company's new A19 Pro doesn't just pack more power - it fundamentally reimagines mobile computing around artificial intelligence, while Apple simultaneously cuts ties with longtime chip suppliers Broadcom and Qualcomm. The iPhone Air, which hit stores Friday, houses three breakthrough chips that collectively give Apple unprecedented control over its mobile destiny. The A19 Pro introduces neural accelerators embedded directly into each GPU core, the N1 marks Apple's first custom wireless chip for iPhone, and the second-generation C1X modem pushes the company closer to complete silicon independence. "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," Apple VP of platform architecture Tim Millet told CNBC in an exclusive interview at Apple Park. The timing couldn't be more critical. Apple faces mounting pressure from Wall Street over its AI strategy while competitors like Google and OpenAI dominate headlines with their large language models. But instead of chasing the cloud AI race, Apple's betting everything on device-based intelligence. The A19 Pro's neural accelerators work similarly to tensor cores in Nvidia's H100 chips, allowing seamless switching between 3D rendering and neural processing within the same program. "The integration of the neural processing is reaching MacBook Pro class performance inside an iPhone," Millet explained. "It's a big, big step forward in ML compute." This isn't just about faster Siri responses. Apple's building the foundation for what Millet calls "all the important on-device AI workloads that are coming." The new front camera exemplifies this vision - it uses AI to detect faces and automatically switches to horizontal photo mode, leveraging nearly every capability in the A19 Pro simultaneously. The wireless and modem story tells an equally dramatic tale of supply chain revolution. Broadcom had been Apple's primary wireless chip provider for over a decade, while dominated iPhone modems since 2020. Apple's N1 wireless chip now powers the entire iPhone 17 lineup plus the iPhone Air, offering improved Wi-Fi location awareness that reduces GPS dependency and extends battery life. The C1X modem, exclusive to iPhone Air, delivers twice the speed of its predecessor while using 30% less energy than equivalent. Ben Bajarin, CEO of Creative Strategies, expects Apple to "completely phase out" within the next couple of years. "It may not be as good as Qualcomm's yet, in terms of just overall throughput and performance, but they can control it and they can make it run at lower power. So you're going to get better battery life," Bajarin noted. The market implications extend far beyond individual chips. Apple's vertical integration strategy positions the company to control every aspect of the AI experience, from hardware acceleration to power management to privacy protection. While and fight over cloud-based AI dominance, Apple's creating an entirely different battlefield centered on personal, private, responsive AI that never leaves your device. Manufacturing adds another layer of strategic complexity. Apple's A19 Pro chips are made at cutting-edge 3nm process in Taiwan, but the company plans to manufacture some chips at TSMC's new Arizona facilities by 2028. This shift gains urgency following Trump's announcement of 100% tariffs on chips from companies not manufacturing domestically, prompting Apple to increase its U.S. spending commitment to $600 billion over four years. The neural accelerator architecture hints at Apple's broader ambitions. When asked if similar technology will appear in the M5 Mac chip, Millet simply said, "We have a unified approach to architecture." Translation: every Apple device will soon run on AI-optimized silicon designed in Cupertino. Privacy remains Apple's key differentiator in the AI wars. "It is efficient for us. It is responsive. We know that we are much more in control over the experience," Millet emphasized. While competitors rely on cloud processing that raises data security concerns, Apple's betting that consumers will choose local AI that keeps personal information locked on-device. The A19 Pro also addresses practical concerns from the iPhone 15's overheating issues. New vapor chamber cooling technology, laser-welded directly to the chip and integrated with the aluminum unibody design, ensures the neural accelerators can run at full capacity without thermal throttling. For developers, Apple's creating what Bajarin calls "the best place to run their AI." The company isn't building its own large language model to compete with ChatGPT or Gemini. Instead, it's positioning iPhone as the ultimate platform where third-party AI services can deliver their best performance through Apple's optimized hardware and software integration.
