What is octa core processor in mobile and how it works?

An octa-core processor in a mobile is a chipset containing eight individual processing cores that work together to handle all the operations and tasks on the device. These processors usually use big.LITTLE architecture developed by ARM, combining high-performance “big” cores with power-efficient “LITTLE” cores. 

What is octa core processor in mobile

An octa-core processor in mobile indicates a chipset design that allows smartphones to balance performance and efficiency. They have revolutionised mobile computing through their multi-core architecture and intelligent task distribution. While symmetric cores are common in PCs, most mobile devices rely on ARM’s asymmetric architecture.

An asymmetric architecture mixes high-performance cores with efficiency cores to allow mobile devices to be both powerful without impacting their battery life. The likes of Qualcomm, MediaTek, and Samsung use this architecture to design octa-core mobile processors, while Apple‘s M-series chips also utilise the big.Little architecture.

What is octa core in mobile

The primary thing to know about an octa-core processor in mobile is that not all cores are active at the same time. Here’s how it works:

Task distribution

The first step is task distribution, where the operating system assigns tasks to appropriate cores with heavy apps using performance cores and background apps using efficiency cores.

Dynamic design

These cores activate and deactivate based on demand, and clock speeds also adjust automatically for real-time optimisation of power consumption.

Parallel processing

The octa-core processor in mobile is also designed for parallel processing, allowing multiple apps to run simultaneously. This allows for faster multitasking and app switching while improving gaming performance.

FAQs

Q1: Is octa-core better than quad-core?

A: Yes, an octa-core processor is better than a quad-core processor for multitasking and can handle more demanding applications while offering energy efficiency.

Q2: Do all eight cores work simultaneously?

A: Not always, since cores activate based on demand with light tasks using fewer or efficiency cores to save battery.
