Are you going to buy a smartphone or you have a phone but you don’t know what’s Inside your Smartphone ? dual-core, quad-core, octa-core, Snapdragon, Mediatek what exactly are these? So let’s figure out.

What’s a CPU?

A CPU is a single computing component with two or more independent actual processing unit called “cores”, which are the units that read and execute program instruction. The instructions are ordinary CPU instructions but the multiple cores can run multiple instructions at the same time. Manufacturers typically integrate the cores onto a single integrated circuit which we know as processor.

Basically, a processor executes what you want your smartphone to do. behind that amazing touchscreen display is a full-fledged computer, responsible for telling your apps how to function, your GPS how to get you home and many more things. The processor is the brains of the operation.

Understanding Multiple Cores

As we know a core is a single processing unit, which executes the task or a process. Now it’s true the more core you have the more task or process your phone will do. Aftermath, apps load quickly, a better multitasking, you can capture high-quality photos or HD video and then browse through your collection without pause. Games don’t get bogged down.

All chips being used in smartphones like Android, Windows Phone and Apple devices-are designed by ARM. So ARM processors form the basis of every phone. The entire system is placed on a single chip, popularly known as SoC (System on Chip). ARM has come out with different designs like the Cortex A5, A7, A8, A9 and A15. According to experts, each chip is better than its predecessor. For instance, the single-core A9 chip will dominate the A8.

Are these factor enough?

Probably not, having a multiple core processor is not enough, and then the clock speed comes in. A clock speed which is basically measured in MHz (megahertz) or GHz (gigahertz). The higher the number of cores and the higher the clock speed can result a more powerful and much faster smartphone. But there might be an exception, a 2 ghz quad-core cpu will deliver a far better performance than the 1 ghz octa-core cpu will. Even if it has eight core it will not match in front of the quad-core processor, just because of the clock speed. The google nexus 5 is a best example for this.

Conclusion

Now you know what makes a processor a good processor. A high-end processor means a high-end processing which basically stands for heavy gaming and multitasking. Some of you might not need that kind of high-end feature, maybe the work you’ll do in your smartphone can be easily taken care off by the smaller processor. Maybe the apps you use will never fully utilize the processor. It is more like buying a Gaming PC and using it for web browsing, I’m sure you’ll have a super fast app working but the overall use of the PC is redundant because you can do that same work in less high end computer. So, please don’t go out there and buy that high end phone just because its new.
