What is the Processor in Mobile Phones? Quad-core vs Octa-core, All About Phone Processor.

Today, smartphones are not just a device for calling, but a personal gadget that organizes various tasks for you. You do many works like play music and videos, web browsing, taking photos and videos and so many more. To manage and perform all those works, your phone needs a processor. That’s why just like the camera, display, memory size, the phone’s processor is also one of the important factors deciding to purchase a device. In the same way, the phone companies are coming with multicore processors such as Quad-core, Hexa-core, and Octa-core in their flagships to enhance performance.

Choosing a smartphone according to the processor is quite difficult for most people. And, it’s necessary to get a smartphone with the right processor as per your requirement. Many technical terms can make you a bit confused. So to help you, here’s complete detail to make you understand What is a mobile phone processor? So, you can choose an appropriate processor smartphone with the right amount of power and fit in your budget.

 

What is a processor in the mobile phones?

The processor is just like the brain of your Smartphone. Almost everything on your phone depends on it. The phone processor, which is also known as the chipset, controls everything in your phone and check whether all functions are working as they should do. It’s an engine that finds how to work using all the available resources. Every command that you give to your phone initially goes to its processor. And as an output, you see visual changes on your display. This process completes in a fraction of second.

 

Importance of processor in mobile phones

The central hub of your smartphone is the processor, which gets and executes each command. You can’t imagine it performs billions of calculations in just a second. Everything in your phone directly controls by phone processor, which results in the effectiveness of the application you run.

Each application in your phone such as camera, music player, email, browsing, processes through your phone’s processor. A slow or old processor could make you experience slug, delay, and limited performance, regardless of carrier, operating system or brand.

 

What are the factors affect phone processor speed?

The processor speed at which it performs tasks depends on some factors, such as the number of processor cores and the clock speed. A processor with high clock speeds and more cores work faster comparing lesser clock speed and cores.

 

Processor Cores:

A processor or CPU can have multiple cores which are called Dual, Quad, Hexa, and Octa-core. But the question is ‘What these cores do on your phone?

The processor cores distribute and channelize the tasks that come to it while you use your phone. One core in a processor can process certain instructions at a time while having multiple cores; these instructions assign to the next core of the processor to be completed. That result lesser time taken by your phone performing a work. That’s the reason multicore processor phones are comparatively faster and functions smoothly.

 

Clock Speed:

The clock speed meaning the number of instructions the processor can execute in a second. For example, a 1GHz (Gigahertz) processor is capable to process 1 billion instructions per second. In other words, higher clock speed is directly related to phone speed. That simply means that phones with higher clock speeds are faster.

Phones with multi-processor cores and higher clock speed are comparatively more expensive. But on the other hand, it influences the speed and performance of your smartphone.

 

 

Dual-core vs Quad-core Vs Hexa-core Vs Octa-core processor

Dual, Quad, Hexa and octa cores are nothing but the number of cores in the processor. Here, Dual, Quad, Hexa, and Octa means 2,4,6 and 8 respectively. For example, an Octa-core processor has 8 cores.

A Quad-core Processor has two sets of a Dual-core on the chip. In the same way, an Octa-core processor has two sets of Quad-core processors on the chip. Similarly, Hexa-core consists of a Quad-core + Dual-core processor.

The processor speed goes faster in successively added cores because it distributes the work and completes it fast. But that doesn’t mean an Octa-core processor has doubled in power than a Quad-core. Subsequently, not every time your phone required multi-cores. White simply reading email or clicking a picture doesn’t require 8 cores of your chipset to process. But in high-end gaming, it may require all the 8 cores.

An appropriate number of cores and the efficiency can provide a better device that can fulfill your overall requirements. For example, Apple iPhone11 Using A13 Bionic chipset consists of two high-performance cores and four energy-efficient cores, which is faster than some Octa-core processor phones. And wonderfully the iPhone 11 is power efficient too.

Do all company’s phone processors perform the same?

Two smartphones have the same 1GHz processors that don’t necessarily perform the same. The reason behind is different chipset manufacturers use different ways for designing their processors or SoC (System-on-Chip).

Currently, few major companies are there in the mobile processor market as MediaTek, Nvidia, Qualcomm, Samsung, and Texas Instruments. These companies create their CPUs with their different approaches. However, the architecture of all of them is the same, which is ARM. Here, ARM is the company that gives the architecture for mobile processors to the processor makers under certain licenses.

Under this license and guidelines of ARM, some makers offer fewer cores but higher clock speed where another offers more core and less clock speed. They change the proportion and combination of cores and clock speed in different SoC. For example, one company is offering a Dual-core processor with 1.8GHz while another is Quad-core with 1.2GHz. That results in variation in the speed and performance of your phone.

Do you need many cores in the phone processor?

The fact is that you don’t need that much processing power for most of the tasks using a smartphone. For example, Just navigating through home screens, messaging, and browsing doesn’t need a much powerful CPU. However, HD video recording, high-speed gaming, and photo editing require some power.

Multicores in the processor consume more power from your phone battery which results in a faster battery drain. So, a phone with an Octa-core processor chipset needs an advanced technology battery so that the phone can perform much faster without compromising battery life.

 

How to choose a phone based on the processor?

As mentioned above, the processor performance depends on two factors: First, its cores and the other is clock speed. You can choose an Hexa-core or Octa-core processor device if you work heavily on your phone. For example, if you are a gamer then for high-end gaming you need a powerful processor with a higher number of cores with higher clock speed. But if you usually check emails, click photos or play music, your phone doesn’t need so many cores in the processors.

In other words, if you unnecessarily get a high-end processor without your use, it means you are expending more than actual requirements. And, not to forget, a higher number of cores means faster battery drain.

However, some new Octa-core processor phones are coming with a fine balance in efficiency and speed. For example, Qualcomm’s new Snapdragon 845 chipset offers eight cores. Out of the cores, four are clocked at 2.8GHz to provide maximum performance, and the remaining four are clocked at 1.7GHz, to deliver efficiency so that the device consumes less battery.

There are two major companies, Qualcomm and MediaTek, providing chipset to the phone companies. Both companies have various chipsets with different classes. Qualcomm has launched its flagship processor Snapdragon 845 which is the highest performing yet. And most high-end phones are featuring this SoC. On the other hand, MediaTek also supplies entry, mid and premium-range of processors. One of its high-end set is Helio X.

The Outline

As you consider camera quality, display screen, or other few features before buying a phone, the processor is also one of the important factors you should consider. Because all you do on your phone controls by it. Also, the phone performance is equally depending on your phone processor.

Phone Technologies are growing and we have started seeing Octa-core processor phones. But you should also consider the battery capacity while buying them because the higher number of cores means higher consumption of the battery’s power. However, the companies are also working to design multicore processors phones using new battery technology, so that it can easily be compatible with the high-end processor and fit into your budget.
