Dual core vs Quad core vs Hexa core vs Octa core vs Deca core processorIs there a difference? Now, a year later everyone is moving to octa-core processors. Octa-core chips have double the number of processor cores of quad-core chips, right? The terms octa-core and quad-core denote the number of processor cores in a CPU. Octa is eight, quad is four.
Is there a difference? Now, a year later everyone is moving to octa-core processors. Octa-core chips have double the number of processor cores of quad-core chips, right? 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 — 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. So, octa-core it is.

ARM has iterated on this setup every year since, providing more capable chips on both halves of the octa-core divide. A number of major mobile chip manufacturers have based their efforts on this big. More recently, Qualcomm switched to the big. Very little, as it turns out. 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?
Apple manages to get decent energy efficiency and performance out of a dual-core setup, after all. Having gone octa-core for its top end Snapdragon and the mid-range processors this year, both have had their issues. LITTLE blueprint can be seen as one possible solution among several to a long-standing smartphone problem — awful battery life.
