Sources: Apple plans to use TSMC's N3E 3nm chipmaking process, expected in H2 2023, for its A17 chips in some 2023 iPhones and its M3 chips for Macs

Context & Ripple Effects
Apple’s reported N3E plan advances an earlier expectation that it would be among TSMC’s first 3nm customers. It also puts a more specific process and product pairing behind prior reports of 3nm Mac chips arriving in 2023.
The intervening roadmap reporting had pointed to 5nm for the A16 and late-2022 Macs, making the reported A17 and M3 shift the next manufacturing-node transition across Apple’s phone and computer silicon.
First-order effects
- Apple would assign TSMC’s N3E process to both A17 chips in some 2023 iPhones and M3 chips for Macs, tying two major product lines to the same updated manufacturing technology.
- TSMC would gain Apple as the reported first adopter of its updated 3nm production process, with demand spanning iPhone and Mac chips.
Second-order effects
- Apple’s reported use of N3E after 5nm A16 and Mac chips concentrates its next product-cycle execution on TSMC’s ability to bring the updated process into production in the second half of 2023.
- The earlier expectation that Apple and Intel would be first 3nm adopters means Apple’s N3E timing becomes a benchmark for other customers seeking TSMC’s leading-node production.
Third-order effects
- If Apple continues moving iPhone and Mac processors onto successive TSMC nodes together, its product cadence becomes more tightly coupled to a single foundry’s process roadmap.
- The report reinforces a leading-edge chip market in which access to updated manufacturing processes is a strategic differentiator for large device makers, rather than a component choice made independently by each product line.
The trend: Apple is increasingly synchronizing its iPhone and Mac silicon roadmaps around TSMC’s successive leading-edge process transitions.
