Explaining Mobile Processor Jargon - nm, GHz, CPU, GPU and More

Picking a new phone can mean getting lost in specs like nm, GHz and MPs. Let’s demystify what these key mobile processor terms mean.

Nanometers (nm)  

The size of the transistors that make up a chip. Lower nm like 5nm means smaller, more densely packed transistors for better efficiency and performance.

Gigahertz (GHz)  

Processor clock speed indicating how many operations can be executed per second. Higher GHz typically means faster processing.


Central processing unit handles main device tasks like operating system, apps, phone functions. More cores means handling more tasks simultaneously.


Graphics processing unit handles visuals and high resolution displays. Important for gaming, video and AR.


Digital signal processor processes sensor data like camera feeds and voice commands quickly. Critical for photos and voice assistants.


Neural processing unit runs AI/ML models efficiently right on device for features like live translations.


An individual processing unit inside a CPU. More cores allow parallel processing for speed and smoother multitasking.


Processor architecture (32-bit or 64-bit). 64-bit allows accessing more memory so is better. 

Understanding these key terms helps you decipher phone specs to determine the right chipset for your needs - whether that’s gaming, photography or just seamless multitasking.
