Intel Finally Lands Apple—But Only for Legacy and Mid-Range Chips
Intel has begun manufacturing chips destined for Apple’s iPhones, iPads, and Mac computers, marking the first time in six years that Apple has returned any silicon production to Intel. The collaboration centers on Intel’s 18A-P process, which is being used to produce legacy and mid-range processors rather than Apple’s cutting-edge A-series and M-series chips. Roughly 80% of the orders are reportedly for iPhone components, mirroring Apple’s real-world device sales mix and turning this into a high-volume but lower-prestige engagement. These are not the processors powering flagship iPhone Pro models or top-tier MacBook Pro systems; instead, they serve as workhorses in older-generation and non-Pro devices. For Apple, this arrangement creates room to experiment with Intel’s foundry capabilities without jeopardizing its most advanced products, while Intel gains a critical, demanding customer to stress-test its nascent foundry ambitions.
Why Apple Is Diversifying Its Chip Suppliers Away from TSMC
At first glance, Apple’s move might look like a win for Intel, but it is primarily a strategic play aimed at TSMC competition. For years, TSMC has been the dominant Apple chip supplier, handling virtually all of the company’s advanced-node silicon. That pipeline is now crowded as AI and high-performance computing drive intense demand for cutting-edge capacity from companies like Nvidia and AMD, as well as cloud providers designing their own accelerators. Apple fears a future in which TSMC prioritizes AI chips over consumer processors, constraining capacity for iPhone and Mac silicon. By shifting legacy and mid-range iPhone chip manufacturing to Intel, Apple reduces its vulnerability to any single foundry. It also gains leverage in future negotiations with TSMC, signaling that it has a credible alternative for at least part of its production if capacity or pricing ever becomes unfavorable.
Intel’s 18A-P Process: A High-Stakes Trial Run, Not a Breakthrough
The chips Intel is producing for Apple rely on its 18A-P node and Foveros packaging, but this technology is still playing catch-up to TSMC’s most advanced processes. According to reports, Intel’s current production yields lag behind TSMC, prompting an internal goal to boost yields by around 50–60% by 2027. The initial phase is essentially a multi-year trial: small-scale legacy chip production through 2026, ramping in 2027, expanding into 2028, and tapering off as the 18A-P generation ages. Importantly, even if everything goes smoothly, TSMC is expected to maintain more than 90% of Apple’s chip supply over the near term. That means Intel’s work is significant but still peripheral in Apple’s broader silicon roadmap. Apple is using this period to rigorously test Intel’s ability to handle real-world volume, complex design feedback, and rapid production adjustments without risking its flagship products.
What This Means for the Future of Apple, Intel, and TSMC
For Intel, winning Apple’s legacy and mid-range chip work is both an opportunity and a source of pressure. Apple is known for exacting standards and huge volumes, making this engagement a critical test of Intel’s foundry strategy. Success would give Intel a marquee customer reference and a compelling case when pitching other major brands. Failure would reinforce skepticism about its ability to rival TSMC. For Apple, running parallel iPhone chip manufacturing across TSMC and Intel creates a real-world rehearsal for a potential dual-sourcing future, reducing risk if supply shocks or AI-driven capacity shifts occur. TSMC, meanwhile, remains firmly in control of the most advanced Apple silicon and the majority of its orders. Yet the message is clear: the era of a single dominant Apple chip supplier is being slowly, deliberately challenged, as all three companies reposition themselves for a more fragmented and competitive foundry landscape.
