Octa Core vs Quad Core – Which is Better for You?

Octa Core vs Quad Core – Which is Better for You?


Ans :  Hello everyone! Here today, with yet another much-debated topic and would like to clear the clouds with this article.
Nowadays while searching for a new phone we always tend check out the phone with best specs ,such as, processor,ram,rom,camera etc. and it's this tendency that the smartphone manufacturing companies cash on. They play the number game. One such thing is marketing of octa-core processors over the dual or quad core processors.

The terms octa-core and quad-core denote the number of processor cores in a CPU. Octa is eight, quad is four. So far, so obvious.

But the key difference between the two – at least when talking about mobile chips in 2019 – is how these processor cores are set up.

In the case of quad-core chips, each core can be put to work simultaneously on a given task, enabling fast and fluid multitasking, smooth 3D gameplay, and super-speedy camera performance, among other things.

Modern octa-core chips, meanwhile, simply have two sets of quad-core processors, which split various tasks between them according to type. Most of the time, the lower-powered set of cores will be employed. When advanced tasks are needed, however, the faster set of four cores will kick in.

A more accurate term than octa-core, then, would be “dual quad-core”. But that just sounds confusing, and it’s not nearly so marketable. So, octa-core it is.

Octa-core vs Quad-core: Purpose

What’s the point of having two sets of quad-core processors handing off tasks to one another, then? It’s all about energy efficiency.

The more powerful a CPU is, the more power it has to draw from a device’s battery. This poses a problem, given that smartphone battery technology hasn’t advanced at anywhere near the rate of mobile processor technology.

The result: as smartphones have gotten more advanced, so battery life has plummeted.

The truth, however, is that you don’t really need that much processing power for the vast majority of smartphone tasks. Navigating through your home screens, checking messages, and even browsing the web aren’t particularly power-hungry tasks.

However, HD video, gaming, and photo manipulation most certainly are.

Combined with the fact that CPU manufacturing processes have gotten so precise now that you can squeeze much more onto a single chip, the octa-core concept seems to be a practical, if slightly inelegant, way to lengthen a modern phone’s battery life without compromising performance where it matters.

So, what’s the difference between octa-core and quad-core in the modern smartphone business? Very little, as it turns out.

That octa-core term is more than a little misleading, as it doesn’t mean the doubling of quad-core , multi-core performance that it suggests. Rather, it represents two independently operating quad-core set-ups squeezed together on one chip for the purpose of greater energy efficiency.

Is such an octa core setup superior to a quad-core one? No, not necessarily. Apple manages to get decent energy efficiency and performance out of a dual-core setup, after all.
