Difference Between Dual Core and i3

A multi-core processor refers to a computer processor on one unsegregated circuit with two or more discrete processing units, named cores, every one of which reads and executes program instructions. The directions are ordinary CPU directions; however, the sole processor can run instructions on separate cores at an equivalent time.

Dual Core vs i3

The main 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. Both the processors have their individual controlling system, because of which they possess the ability to function independently.

 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. Intel I core 3 is superior to dual-core as a result of increased speed, the capability of handling heavy software with normal speed.

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. And as both the processors are coupled together, they make the operations quicker than a single processor. The dual-core processor is well-liked owing to its potency in juggling different tasks. As there are two execution cores instead of 1, it has a self-employed network.

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. This is because they are basically an expansion of the same technology that provides for more than two processors to work in sync with each other. 

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. As it has two cores in 1 chip, it delivers enhanced performance.

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. It comes with either three MB or four MB of cache. LGA 1150 or LGA 1155 socket is utilized on the motherboard. 

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. They are also called Quad cores. Core i3 is more often used in laptops. While using a Core i3 processor, one can use a laptop for five to six hours once charged. It comparatively generates low heat and has more capacity to handle bulk software. And all of the above with optimal speed.

Main Differences Between Dual Core and i3

  1.  The working of Dual-core is based on two sub-cores built within a processor. Whereas the Intel I3 works on four sub cores, which is why it is also known as a Quad-Core processor.
  2. The dual-core belongs to the second generation of processors, and the i3 belongs to the third generation processors.
  3. The speed of the dual-processor is comparatively less than the i3 processor.
  4. The i3 processor is comparatively way more accurate than the dual-core processor.
  5. The dual-processor socket is 775, whereas i3 has an 1156 socket.
Difference Between Dual Core and i3


Intel Core represents efficient mid-range customer-oriented and work-based computer CPUs- central processing units. The marketing, advertising, and selling are carried out by the Intel Corporation. Prevailing mid to high-end Pentium processors were replaced by intel upon their release.

As a result, the Pentium processors were moved to the entry-level, and the Celeron processors to a lower end. Several other capable versions of server and workstation versions of the Core processors are also made available for the consumers in the markets. The Intel Core processors made their debut in 2006. Through the years and many generations have come and gone. Some of the releases are Intel Core i3, Intel Core i5, and Intel Core i7.

All of Intel’s processing units have many similarities yet are distinctive in their own way. These processors, which are available in a wide range of variations and designs, are admirable and trustworthy. The Intel Core i3, Intel Core i5, Intel Core i7, and Intel Core i9, with the X-series of Intel Core CPUs, were released till August 2017.

There are more processors in the making, a few of them have been announced, and some waiting to be released. After all of these years, the intel processors are still successfully running in the market, withholding their position as one of the top brands. Intel processors are also referred to as budget-friendly and reliable processors by consumers around the world.
