Dual Core vs i3

The difference between Dual-Core and i3 is that the dual-core is an older processor, and the i3 is the latest processor. The two processors are manufactured and sold by Intel. The two processors have numerous similarities in their development and style. However, they are distinctive in their own way.

Dual Core vs i3

The term “dual-core” merely means that a processor has two processing cores inside the package. It is basically a C P U with two confined into a singular circuit.

 The latest dual-core processor from Intel is the Core i3, succeeding the Core 2 pair and Dual Cores. It presents many style changes that give vital performance gains.

What is Dual Core?

In simple terms, a dual-core processor is a CPU with two processors integrated into a single circuit. Each of the two processors has an independent cache as well as a controller, which is why both the processors can function independently.

The availability of resources is abundant for the operating system, and such resource abundance enables it to handle even the most intensive computing tasks side by side. The dual-core processors are quite similar to multi-core processors.

Many CPUs use dual-core technologies such as Intel Core Duo, AMD X2, and dual-core PowerPC G5. A dual-core processor is useful as it works more efficiently than a single processor, takes up less space and energy.

What is i3?

The Core i3 is a dual-core computer processor that was developed and manufactured by Intel and initially introduced and publicized in 2010, out there to be utilized in desktop as well as laptop computers. 

It is a part of the three forms of processors within the “i” series. The “i” series is also called the Intel Core family of processors. Starting from 1.30 gigahertz up to 3.50 gigahertz, the Core i3 processor has it’s available at multiple speeds.

DDR3 1333 or DDR3 1600 is the most commonly known type of RAM used with a Core i3 processor. Core i3 and dual-core are used interchangeably, too, as both of them have two cores. The major distinction is that specific high-end Core i3 processors include four cores.
