Sources: Apple's manufacturing partner TSMC has started mass production of 7nm processors for iPhones launching later this year
- More-efficient 7-nanometer processors coming later this year — Samsung is also working on the next-generation chip technology
Context & Ripple Effects
This 2018 report is the moment Apple's silicon strategy locks onto a single foundry: TSMC begins mass-producing 7nm processors for that year's iPhones while Samsung races on the same next-generation node, making process leadership — not just chip design — the differentiator in flagship phones. The arc that follows shows how durable that bet became: Apple later moved its Macs onto its own TSMC-built chips via a plan built around the 5nm A14 generation, and by 2023 the relationship had hardened into a deal where TSMC absorbs the cost of chip defects, giving Apple early access to leading-edge nodes before rivals.
First-order effects
- iPhones launching later in 2018 ship with more efficient 7nm processors, giving Apple a power-efficiency edge over phones still on older nodes for that cycle.
Second-order effects
- Samsung's parallel work on next-generation chip technology turns every node transition into a head-to-head race between the two foundries for Apple-class customers, pressuring yields and pricing at the leading edge.
Third-order effects
- The pattern holds across the decade of related coverage: Apple concentrates ever more silicon with TSMC — from Mac CPUs to 4nm 5G modem chips meant to cut Qualcomm reliance — so each node shrink widens Apple's lead while deepening its single-foundry dependence, a structural risk when TSMC's Taiwan fabs dominate supply.
The trend: Flagship mobile silicon is becoming a foundry-process race, with Apple using exclusive early access to TSMC's newest nodes as a compounding competitive moat over Samsung and other chip buyers.
