Over a year ago, industry watchdogs posited that Apple was patiently waiting in line at the front of TSMC's 2 Nanometer GAA "VVIP queue." The securing of cutting-edge manufacturing processes seems to be a consistent priority for the Cupertino, California-headquartered fabless chip designer. Current generation Apple chipsets—at best—utilize TSMC 3 nm (N3E) wafers. Up until very recently, many insiders believed that the projected late 2026 launch of A20 SoC-powered iPhone 18 smartphones would signal a transition to the Taiwanese foundry's advanced 2 nm (N2) node process. Officially, TSMC has roadmapped the start of 2 nm mass production around the second half of 2025.

According to Jeff Pu—a Hong Kong-based analyst at GF Securities—the speculated A20 (2026) chipset could stick with N3P. Leaks suggest that aspects of Apple's next in line "A19" and "A19 Pro" mobile SoCs could be produced via a 3 nm TSMC process. MacRumors has picked up on additional inside track whispers; about Apple M5 processors (for next-gen iPad Pro models) being based on N3P—"likely due to increased wafer costs." Pu reckons that Apple's engineering team has provisioned a major generational improvement with A20's AI capabilities, courtesy of TSMC's Chip on Wafer on Substrate (CoWoS) packaging technology. This significant upgrade is touted to tighten integration between the chip's processor, unified memory, and Neural Engine segments. Revised insider forecasts have positioned A21 chip designs as natural candidates for a shift into 2 nm GAA territories.

Apple is reportedly considering diversifying its chip manufacturing strategy with a new silicon manufacturer: Intel. While the upcoming iPhone 17 series, expected next year, will likely feature A19 chips produced by TSMC, a recent rumor from Chinese leaker Fixed Focus Digital hints at a potential switch to Intel for the A20 chipsets powering the 2026 iPhone 18 series. The A18 and A18 Pro chipsets debuted alongside the iPhone 16 series in September 2024, manufactured using TSMC's N3E node. Apple's A19 chips are expected to upgrade to TSMC's N3P node. According to the source, Apple is seeking an Intel 20A node. However, since the A20 node is canceled in favor of 18A, Apple could be an Intel Foundry customer for either 18A or 14A nodes.

Despite the buzz, skepticism persists. Intel has historically struggled with process node transitions and even outsourced production of its Arrow Lake CPUs to TSMC, raising questions about its readiness to deliver on Apple's demands. On the other hand, alternative reports suggest Apple might stick with TSMC's yet-unnamed 2 nm node for the A20, maintaining continuity in its supply chain. As the iPhone 18 series remains two years away, much can change. For now, we are left speculating whether this rumored collaboration with Intel represents a new chapter in Apple's chipset innovation or just a rumor with little substance. If the US government mandates more domestic production, chip designers could be looking at some of the more local manufacturing options, like Intel does on US soil. That could force Apple, NVIDIA, AMD, and Qualcomm to look into Intel's offerings.
