What is nm in mobile processor and why does it matter?

The “nm” in mobile processors stands for nanometres and refers to the manufacturing process node size. It refers to the size of the transistors on the processor chip, with smaller values like 3nm or 5nm delivering powerful performance and improved energy efficiency. Smaller nm values also mean more transistors can be packed into the same space.

What is nm in mobile processor

NM means the lithography of the processor, and it shows the manufacturing precision of the mobile processor. Here’s how the mobile processor manufacturing has evolved:

– 14nm: Early smartphones came with 14nm processors and had higher power consumption
– 10nm: Improved efficiency and moderate performance gains
– 7nm: Significant power savings and faster performance
– 5nm: Flagship standard delivering efficiency and performance boost
– 3nm: Latest lithography delivering maximum performance per watt

When it comes to mobile processors, smaller is better since processors built on smaller nm nodes offer more processing units in the same chip area. They also have reduced distance between transistors, which allows for faster switching speeds. Their biggest advantage is lower power consumption and extended battery life.

Apple A18 and A18 Pro chips, which power iPhone 16 and iPhone 16 Pro respectively, are built on a 3nm process. Qualcomm Snapdragon 8 Elite and MediaTek Dimensity 9400 are also built on a 3nm process, while Google’s Tensor G4 is based on a 4nm process.

FAQs

Q1: Does smaller nm value always mean better processor performance?
A: Generally yes, but the performance also depends on processor architecture, core count, and clock speed.

Q2: Can older phones be upgraded to newer nm processors?
A: No, processors are permanently integrated into motherboards of phones and cannot be upgraded.

Nanometre (nm) values in mobile processors indicate transistor size, with smaller nm delivering better performance and longer battery life. A chip fabricated using a smaller node size has become crucial for modern smartphone performance and efficiency.
