Apple’s A20 Pro, unveiled at the September 9 event, is the first smartphone processor built on TSMC’s 2-nanometer process, and it drops into the iPhone 18 Pro, iPhone 18 Pro Max and the new foldable iPhone Duo. The chip marks Apple’s split from Qualcomm modems in its flagships and resets the annual performance comparison against Snapdragon 8 Elite Gen 5 and Samsung’s Exynos 2600.According to details reported by ixbt.com and Apple’s announcement, the A20 Pro uses a six-core CPU layout with two high-performance Super Core units and four efficiency cores. Apple says extra graphite and copper in the packaging deliver 40 percent better performance during long loads, and twice the thermal-throttling resistance of the iPhone 16 Pro generation. Sustained performance, not peak benchmarks, is where the company is placing its bets this year.
Modem in-house at last
The bigger strategic change sits next to the CPU. Apple moved its flagship modems to its own C2 cellular design, ending its dependence on Qualcomm parts at the top of the line. Apple claims higher data speeds and 15 percent lower modem power draw, with a separate N1 chip handling Wi-Fi 7 and Bluetooth 6.The in-house modem push has taken years and cost Apple a legal settlement with Qualcomm along the way. Getting it into the flagship tier, not just the budget iPhone 16e, signals the company now trusts its own radio silicon for the products that carry the brand. Qualcomm still supplies modems for the non-Pro iPhone 18 models, so the split is partial, but the direction is hard to miss.
The race behind it
Apple is not alone at 2nm. Samsung’s Exynos 2600 was actually the first smartphone chip on TSMC’s 2nm node, per 9to5Google’s reporting, while Google confirmed its Tensor G6 in the Pixel 11 stays on 3nm after earlier rumors of a 2nm jump. Qualcomm’s Snapdragon 8 Elite Gen 5 remains the Android performance benchmark and powers most 2026 flagships.
| Chip | Process | Flagship device |
|---|---|---|
| Apple A20 Pro | TSMC 2nm | iPhone 18 Pro, iPhone Duo |
| Qualcomm Snapdragon 8 Elite Gen 5 | TSMC 3nm | Android flagships |
| Samsung Exynos 2600 | TSMC 2nm | Galaxy flagships |
| Google Tensor G6 | TSMC 3nm | Pixel 11 |
Benchmark claims from launch events are best taken with a grain of salt, and Apple’s own materials focus on sustained performance rather than peak numbers. Independent testing will settle the comparison once review units are out, likely around the September 22 retail launch date.
What it means for buyers
The chip comes inside a wider lineup that got more expensive across the board. The foldable iPhone Duo starts at $2,000 for 256GB and climbs to about $3,000 at 2TB. Apple also extended free satellite messaging for iPhone 14 through 16 owners, buried in the announcement footnotes, and set iOS 27 for release on September 14.Battery figures got the usual headline treatment, with Apple claiming up to 36 hours of video playback on the iPhone 18 Pro and 45 on the Pro Max, credits shared between the more efficient processor, the C2 modem and new battery hardware. The smaller Dynamic Island on the Pro models can now juggle three tasks at once, up from two.The 2nm node itself matters beyond spec sheets. TSMC’s newest process is expensive and capacity is tight, and Apple has historically bought first position at each new node to hold its performance lead. Samsung’s decision to put Exynos 2600 on the same node means Android buyers will get a direct comparison on equal manufacturing footing for the first time in years.
Watching the supply chain
There is a practical question underneath the marketing: whether TSMC can produce enough 2nm silicon for both Apple and Samsung without yield problems in the first year. New nodes usually start with low yields and high per-unit costs, and the iPhone is the highest-volume premium phone on the market. Any supply hiccup would show up first as long shipping estimates on Pro models.Whether the A20 Pro’s real-world gains justify the price increases is the question reviewers will answer in the coming weeks. What is clear already is that the modem transition, not the CPU, is the story with the longest consequences. Every iPhone Apple sells with a Qualcomm radio inside is one that later needs no Qualcomm at all, and that shifts billions of dollars in component spending between two of the biggest names in mobile.
