The nanometer (nm) process technology used in manufacturing these CPUs plays a crucial role in determining their performance, efficiency, and overall capabilities. In a smartphone, the heart of it lies in its central processing units (CPUs). In this blog post, we will look into the significance of different nanometer processes by comparing the 4nm and 6nm (as an example) technologies commonly found in modern smartphone processors.

What is a nanometer (nm) Process?
A nanometer refers to the size of the transistors and other components on a semiconductor chip. In the context of smartphone CPUs, a smaller nm process generally indicates a more advanced and efficient manufacturing technology. Smaller transistors mean more can be packed onto a chip, more tasks can be achieved at a time and leading to improved performance and energy efficiency.
The Leap from 6nm to 4nm:
As technology advances, semiconductor manufacturers strive to shrink the size of transistors to enhance the capabilities of the processors. The transition from 6nm to 4nm represents a significant leap in nanometer processes. This size reduction has several implications for smartphone CPUs:
- Increased Transistor Density:
- The primary advantage of moving from 6nm to 4nm is the increased transistor density. Smaller transistors allow for more of them to be packed onto the same-sized chip. This results in a higher transistor count, enabling the processor to handle more tasks simultaneously and potentially boosting overall performance.
- Improved Power Efficiency:
- Smaller transistors typically require less power to operate. The 4nm process, compared to the 6nm process, can potentially lead to improved power efficiency. This is crucial for smartphones, as it contributes to longer battery life and reduced heat generation.
- Performance Gains:
- The increased transistor density and improved power efficiency often translate into better overall performance. Tasks such as multitasking, gaming, and demanding applications may see performance gains on a 4nm processor compared to a 6nm one.
- Thermal Considerations:
- While smaller transistors generally generate less heat, the 4nm process may still pose challenges in terms of thermal management. Manufacturers need to implement effective cooling solutions to ensure optimal performance without overheating.
There are many players in the chip manufacturing industry such as Samsung, TSM (Taiwan), Nvidia, Qualcomm, and Intel to name a few top players.
All Snapdragon 8 Gen 1 and above are 4nm process processors, Snapdragon 888 5G is a 5nm process, and Snapdragon 4 Gen 1 is a 6nm process.
Nothing Phone 2 5G and iQOO Neo 7 Pro are Snapdragon 8+ Gen 1 are 4nm process processors where as iQOO 11 5G is a Snapdragon 8 Gen 2 processor which is also a 4nm process.
The choice between a 4nm and 6nm process for smartphone CPUs involves a trade-off between increased transistor density, improved power efficiency, and potential thermal challenges. As technology continues to advance, we can expect further refinement of nanometer processes, pushing the boundaries of what is possible in terms of performance and energy efficiency in the palm of our hands.
