TSMC introduced the 2nm manufacturing technology during the 2022 Technology Symposium. At that time, it was reported that the fabrication process would use gate-all-around field-effect transistors instead of FinFET and it would offer either up to 15 percent higher performance or 30 percent lower power consumption than N3E - the process that would be used for the
Since the next iPhones will probably be launched in September, it's safe to assume that the first 2nm A-series chip will debut on the iPhone 17. Apple is usually TSMC's first client to benefit from its new processes, so the iPhone 17 will probably be the only phone with TSMC's 2nm chip next year.
