The smaller the process node, the smaller the feature set in chips including transistors. Smaller transistors mean that more of them can fit inside a chip and the higher a chip’s transistor count the more powerful and energy efficient it is. As a quick example, the iPhone 11 line used the 7nm A13 Bionic which contained 8.5 billion transistors. The iPhone 14 Pro models are equipped with the A16 Bionic which is manufactured using TSMC’s third 5nm enhancement which is dubbed “4nm.” Those chips each contain 16 billion transistors.
Samsung reiterates its roadmap for Samsung Foundry
While TSMC and Samsung Foundry are shipping 3nm chips, Sammy’s chips use gate-all-around (GAA) transistors which allow the gate to come into contact with all sides of the channel reducing voltage leaks and delivering a greater drive current. TSMC is still using FinFET transistors on its 3nm chips which have the gate come into contact with the channel on three sides. TSMC will switch over to GAA when it debuts its 2nm production in 2025.
Samsung says that the first 2nm chips it produces in 2025 will be designed for use in mobile devices such as smartphones and tablets. In 2026, the 2nm process node will also be manufactured for use in high-performance computing, and in the following year, these advanced chips will be produced for use in automobiles.
The company also announced that it is expanding its chip manufacturing capacity by adding production lines in Pyeongtaek, South Korea, and Taylor, Texas.
