Likelihood: Plausible (41-60%) — early details from a single tipster, but consistent with Apple’s recent chip strategy
Apple is reportedly preparing a major silicon leap for the iPhone 18 lineup in 2026, with the first 2nm A-series chipsets on deck. Alongside the standard and Pro models, a long-rumored foldable iPhone is also said to be in the mix, setting the stage for multiple variations of the A20 family.
According to a Weibo tipster who goes by “Mobile phone chip expert,” Apple has internally codenamed its next-gen 2nm chips “Borneo” and “Borneo Ultra.” The standard iPhone 18 is expected to use the A20 (Borneo), while the iPhone 18 Pro, iPhone 18 Pro Max, and the foldable iPhone are tipped to run on the A20 Pro (Borneo Ultra). That mirrors Apple’s recent playbook: two official chips, but multiple bins and configurations across the lineup.
This approach follows what Apple did with the A19 generation. While two chips were announced publicly, three variations ultimately shipped. The iPhone Air is said to use a lower-binned A19 Pro, whereas the iPhone 17 Pro and iPhone 17 Pro Max feature the highest-binned versions with six CPU cores and six GPU cores. Expect a similar spread with the A20 series, even if Apple only markets two names.
What to expect from Apple’s 2nm A20 and A20 Pro
– Manufacturing: TSMC’s first-generation 2nm N2 process, promising better power efficiency and higher performance versus 3nm.
– Core layout: Likely a 6-core CPU split between performance and efficiency clusters, continuing Apple’s proven architecture.
– Pro-tier advantages: Higher GPU and CPU bins for Pro models and the foldable, enabling better graphics, AI performance, and sustained speeds.
The 2nm rollout won’t stop with iPhone. The same N2 process is reportedly being used for Apple’s M6 chip, expected to power an updated 14-inch MacBook Pro and future OLED touchscreen MacBook models. Looking beyond 2026, Apple may transition to TSMC’s enhanced 2nm N2P process around 2027 for further gains.
If these details hold, the iPhone 18 family could mark one of Apple’s biggest annual silicon upgrades, pairing an all-new node with a broader device strategy that includes a foldable flagship. As always, plans can shift before launch, but the trajectory is clear: Apple is gearing up to make 2nm the heart of its next wave of iPhone and Mac performance.
