The technology behind the chips in your iPhone determines not only performance but also energy efficiency and the overall user experience. A hotly debated topic in the tech world is when Apple will make the leap to the next generation - the 2nm chip. Here you can find out why Apple is continuing to use the 3nm process for the iPhone 17 and when you can expect 2nm technology in your iPhone.
For years, Apple has taken an innovative approach to chip development in order to leave the competition behind. But progress in the semiconductor industry is slowing down. Where annual jumps between process nodes were once possible, we now see longer development cycles. We will explain in detail why this is the case and what you can expect in the coming years.
Apple's 3nm cycle: A look at the current status
Apple introduced the first 3nm chips in 2023 with the iPhone 15 Pro – based on TSMC's N3B process. This step marked the beginning of a three-year cycle in which Apple uses the 3nm technology in various variants.
A14 to A16: The evolution of the 5nm process
The A14 chip from 2020 was already based on a 5nm process from TSMC. The subsequent A15 and A16 chips used improved versions of the same architecture (N5P and N4). This development shows how Apple refines existing technologies before moving to the next process node.
3nm: The new basis for iPhone chips
The iPhone 15 marked the beginning of the era of 3nm chips. The N3B process offers better energy efficiency and performance, but Apple will continue to optimize the technology. A switch to the N3P process - the third generation of 3nm production - is planned for the iPhone 17.
When will the 2nm chip be released?
The next big innovation in chip manufacturing is the 2nm process. According to recent reports, TSMC will start risk production of the 2nm process in 2025. Mass production is not expected to start until the end of 2025, which means that the 2nm chip will not be used in the iPhone 18 Pro (2026) at the earliest.
Why no 2nm chip in the iPhone 17?
Apple has deliberately decided not to adopt the 2nm process directly. One of the reasons is that the first generation of new process nodes is often less mature. Instead, Apple will rely on the proven N3P process to ensure stability and efficiency.
Which models will receive 2nm?
Not all iPhone 18 models will be equipped with a 2nm chip. The base models could still use 3nm technology, either in the N3P or N3X variant.
Why do new process nodes take longer?
Silicon manufacturing has reached its limits, and advances in miniaturization are becoming increasingly complex. New process nodes require huge investments and longer development times. The slowdown affects the entire industry, not just Apple.
iPhone: Should you wait for 2nm?
If you always want the latest and greatest technology, it's worth waiting for the iPhone 18 Pro. The 2nm technology is expected to offer revolutionary performance and power efficiency. However, the iPhone 17's N3P process is anything but outdated. It offers a significant improvement over current 3nm chips. The decision is yours: Do you want the most advanced technology as early as possible, or can you settle for a tried-and-tested but optimized process? One thing is certain: Apple will continue to lead the way in chip development, along with TSMC. Looking for the best accessories?
