Apple’s first 3 nanometer chips, the A17 Professional and M3, usually are not even three months outdated, however know-how is all the time shifting ahead, and Apple is already wanting in the direction of the following fabrication course of. The Monetary Occasions studies (subscription required) that the Taiwan Semiconductor Manufacturing Firm (TSMC) is creating a 2nm chip course of that has been demonstrated to Apple and different shoppers.
TSMC, which manufactures Apple’s chips, tasks that mass manufacturing of 2nm chips may very well be prepared by 2025, and the corporate instructed the Monetary Occasions that the method “would be the most superior semiconductor know-how within the trade in each density and vitality effectivity when it’s launched.”
The evolution of the fabrication course of will increase the transistor density within the chip and permits for extra chip cores, extra cache, and different options. For instance, Apple’s M1 Mac chip and A14 Bionic iPhone chip have been manufactured with the 5nm course of. When Apple switched to the 3nm course of for the M3 and A17, Apple was capable of match extra transistors onto the silicon, which elevated the chips’ efficiency, boosted core counts, and allowed for different options. The newer course of additionally improves energy effectivity.
If TSMC and Apple can meet the 2025 aim, that would imply that the iPhone 17 Professional may sport an A19 Professional chip (if Apple sticks to the present naming conference) made with a brand new 2nm course of. Apple usually debuts new chip designs in its iPhone first, so 2nm M-series Mac chips may comply with in late 2025 or early 2026.
However know-how is all the time shifting ahead, and so is TSMC. Analyst Dylan Patel posted on X that TSMC already has a 1.4nm course of in improvement. A TSMC consultant didn’t present a timeline as to when 1.4nm can be prepared for mass manufacturing, however it’s presumably a few years away.
Apparently, TSMC refers back to the 1.4nm course of as “A14,” which will be complicated when contemplating how Apple names its iPhone chips. TSMC has beforehand referred to its 5nm, 3nm, and upcoming 2nm processes as N5, N3, and N2–the “N” stands for nanometer. As Jose Fandos on X factors out, an angstrom is a unit of measurement that is the same as 0.1 nanometers. So as a substitute of calling it N1.4, TSMC has determined to make use of the identify “A14,” the place the “A” stands for angstrom. However because it’s very early, it’s doubtless for the nomenclature to vary between now and launch.
