Intel Reportedly Begins Trial Production of Apple Chips: What This Means for iPhone, iPad, and Mac

For nearly a decade, TSMC has been the sole manufacturer of Apple's custom chips, powering everything from iPhones to MacBooks. However, a fresh report from analyst Ming-Chi Kuo suggests that Intel may soon join the supplier lineup, potentially reshaping Apple's chip strategy. Here's a breakdown of the key details and implications in a Q&A format.

What exactly is Intel testing for Apple?

According to Apple supply chain analyst Ming-Chi Kuo, Intel has begun small-scale manufacturing trials for lower-end Apple chips intended for iPhones, iPads, and Macs. These tests use Intel's advanced 18A fabrication process. Production volumes are expected to increase gradually throughout 2027 and 2028. Kuo did not specify which A-series or M-series chips are involved, but the focus is on less powerful, lower-cost models. Intel's role is limited strictly to fabrication—Apple remains the chip designer, unlike the Intel Mac era when Intel supplied both design and manufacturing for x86 processors.

Why would Apple want a second chip supplier?

Diversifying suppliers offers Apple two major advantages: cost reduction and supply chain resilience. By sourcing chips from both TSMC and Intel, Apple can negotiate better pricing and ensure consistent availability, especially during global disruptions. Additionally, reshoring some production to the U.S. could align with political incentives. Kuo notes that Intel's U.S.-based manufacturing may help Apple gain favor with the Trump administration, which advocates for increased domestic manufacturing. However, despite this shift, TSMC is expected to retain responsibility for over 90% of Apple's chip supply for the foreseeable future.

How does this differ from Apple's previous Intel partnership?

In the past, Apple used Intel-designed processors with x86 architecture for Macs, meaning Intel controlled both the design and fabrication. Starting in 2020, Apple transitioned to its own M-series chips, which are designed in-house and manufactured by TSMC. If Intel now fabricates some Apple chips, it will only handle production—not design. Apple's chip team will continue to create custom ARM-based architectures for iPhone, iPad, and Mac. This represents a fundamental shift: Intel becomes a pure contract manufacturer, similar to TSMC, rather than a design partner.

What is Intel's 18A process, and why does it matter?

Intel's 18A is one of its most advanced semiconductor fabrication nodes, expected to deliver significant performance and efficiency improvements over previous generations. By testing Apple chips on this process, Intel aims to prove its manufacturing competitiveness against TSMC. Kuo reports that Apple is also evaluating other Intel advanced-node technologies. Success with 18A could open the door for Intel to secure more Apple business in the future, though the immediate scale remains small. For Apple, using Intel's cutting-edge process provides a backup option and potential cost leverage without compromising chip quality.

Will Intel eventually manufacture all Apple chips?

No, at least not in the near term. Kuo explicitly states that despite Intel's new role, TSMC will continue to supply more than 90% of Apple's chips. Intel's involvement is limited to lower-end models—likely the entry-level A-series chips for iPhones and perhaps base-tier M-series for Macs. High-end chips like the A18 Pro or M4 Pro/Max will almost certainly remain with TSMC due to its proven yield and advanced nodes. The shift is incremental and strategic, not a wholesale change. An official announcement from Apple or Intel has yet to be made, but multiple sources corroborate these tests.

How does this affect consumers of iPhone, iPad, and Mac?

For everyday users, the immediate impact should be minimal. If Intel successfully manufactures chips for lower-end devices, those products may see slight price reductions or improved availability due to increased competition between suppliers. Performance and battery life are unlikely to change drastically, as Apple's chip design remains the same regardless of fab. However, in the long term, diversifying fabrication could help Apple avoid supply shortages that have plagued the industry. Consumers may also feel indirect effects from geopolitical influences, as U.S.-based production aligns with trade policies. Overall, this is a behind-the-scenes business move that strengthens Apple's supply chain without altering the user experience.
