Apple is diversifying its semiconductor supply chain in a significant shift, as reports indicate that Intel is now making iPhone chips for Apple. This move marks a strategic pivot for the Cupertino giant, which has relied almost exclusively on Taiwan Semiconductor Manufacturing Company (TSMC) for its high-performance silicon over the last decade.
The development comes following a report from the Wall Street Journal that the two companies had reached an agreement, and more recent data from industry analyst Ming-Chi Kuo suggesting that initial production has already commenced. While Apple has long sought to mitigate the risks associated with a single-source supplier, this partnership represents the first tangible step toward a multi-foundry strategy for its core mobile processors.
For Intel, the deal is a critical validation of its Intel Foundry strategy. By securing a client as prestigious as Apple, Intel demonstrates that its advanced manufacturing nodes can meet the rigorous efficiency and performance standards required for the world’s most popular smartphone.
The specifics of the Intel-Apple production deal
According to analysis shared by Ming-Chi Kuo on X, the current production is not focused on Apple’s flagship, cutting-edge silicon. Instead, Intel is producing “low-end/legacy” processors for the iPhone, iPad, and Mac. This likely includes chips for older models that Apple continues to sell to budget-conscious consumers or specific regional markets.
The production is utilizing Intel’s 18A-P series, which leverages Foveros packaging—Intel’s proprietary 3D stacking technology. From a technical perspective, Foveros allows for the vertical integration of components, which can improve power efficiency and reduce the overall footprint of the chip, a necessity for the tight internal constraints of an iPhone or iPad.
The current order mix is heavily weighted toward mobile devices, with iPhone processors accounting for roughly 80% of the volume, mirroring Apple’s broader device sales distribution.
A phased roadmap for adoption
The transition to Intel’s foundries is not happening overnight. The rollout is designed as a gradual ramp-up to ensure yield stability and quality control, which are paramount for Apple’s hardware reputation. The production lifecycle for the 18A-P series follows a specific trajectory over the next several years.
| Year | Production Phase | Expected Activity |
|---|---|---|
| 2026 | Testing | Small-scale validation and initial testing |
| 2027 | Ramp-up | Increase in production volume |
| 2028 | Growth | Continued expansion of wafer orders |
| 2029 | Decline | Phase-out as newer nodes are adopted |
This timeline suggests that while initial production has “kicked off,” the majority of these Intel-made chips won’t reach consumers in significant numbers until 2027. This cautious approach allows Apple to stress-test Intel’s 18A process node before committing its most advanced A-series or M-series designs to the facility.
Reducing the TSMC dependency
The move is widely viewed as a risk-mitigation strategy. Currently, Apple’s reliance on TSMC creates a geographical and operational bottleneck. With the vast majority of advanced chips produced in Taiwan, any geopolitical instability or natural disaster in the region could potentially paralyze Apple’s entire product lineup.
However, industry experts caution that Intel is not replacing TSMC, but rather supplementing it. Kuo notes that TSMC is still expected to retain over 90% of the supply share once Intel’s operations are fully scaled. The most cutting-edge silicon—the chips powering the “Pro” and “Max” models—will likely remain with TSMC for the foreseeable future due to their current lead in the most advanced nanometer nodes.
During my time as a software engineer, I saw how critical the underlying hardware architecture is to the software’s performance. For Apple, the challenge isn’t just finding another factory; it’s ensuring that a chip made by Intel behaves exactly like one made by TSMC so that iOS and macOS can run seamlessly across different hardware sources without performance regressions.
What In other words for the future of Apple Silicon
The partnership extends beyond the current 18A-P series. Reports indicate that Apple is actively evaluating other advanced-node technologies within Intel’s portfolio. This suggests that the “legacy” chips are merely a proof-of-concept. If Intel can maintain high yields and strict adherence to Apple’s specifications, the scope of the partnership could expand to more powerful processors.
This shift also puts pressure on other foundries, such as Samsung, which has previously struggled to maintain a consistent relationship with Apple. By pivoting toward Intel, Apple is betting on a Western-based manufacturing alternative that aligns with broader trends of “onshoring” critical technology production.
The next major milestone for this partnership will be the 2026 testing phase, where the first batch of production-ready wafers will undergo final validation. Until then, the industry will be watching closely to see if Intel can deliver the precision Apple demands.
