The Celeron is none other than a range of processors (CPU) for laptops and desktops. Invented by the American company Intel, Celeron chips are deployed at the time of the advent of the consumer computing market.

Since their beginnings, they have continued to evolve and are now integrated into many PCs.

The choice of the CPU during a new acquisition is essential, you are probably wondering if it is suitable for your use.

We therefore suggest that you present the detailscharacteristics and uses.

We also take this opportunity to explain the difference between the Intel Celeron and the Intel Pentium.

Zoom on the Celeron processor, a product stamped by Intel, the world leader in the microprocessor market.

The definition of the Intel Celeron

The term “Celeron” refers to a range of processors found in inexpensive computers , developed by the company Intel.

As a processor, it is the essential component of a computer, since it is it that executes the instructions given by the operating system . He is the brain of the machine.

The first manufacturer of microprocessors in the world, Intel holds nearly 80% of the CPU market and equips the majority of laptops and desktops, as well as all Apple Macs with processors, thanks to a complete and diversified offer. Among its best-known ranges are the Intel Atom, the Intel Pentium, the Intel Core i3, the Intel Core i5, the Intel Core i7, the Intel Core i9, the Intel Xeon… and the Intel Celeron.

What is a Celeron?

The Intel Celeron was created in 1998 to face competition from other manufacturers then positioned on entry-level microprocessors, such as AMD and Curix at the time.

A low-power processor, the Celeron has therefore been designed more for the economy than performance, to meet the growing demand for affordable computers.

It is integrated as well in portable PCs as in desktop PCs.

The Celeron processor: Economy vs power

Based on the same x86 architecture as the most popular Intel processors, the Intel Core, the Celeron remains the least efficient Intel solution, behind the Intel Pentium, and even further behind the Intel Core i3, the entry of range of the Intel Core. Indeed, it is about the same processor, but with less functionalities.

What about performance?

In its early days, the Intel Celeron processor had only one core, but since the Conroe generation, it has a second.

Currently, the most widely used version is the Intel Celeron Dual Core, although a quad-core version exists (Intel Celeron Quad Core). Knowing that the number of cores determines the capacity of the processor to perform several tasks at the same time, and consequently the speed of the passage from one task to another. The more cores a Celeron processor has, the better it performs.

Its frequency, in gigahertz (GHz), significant to the speed of the processor is generally lower than that of other processors, more efficient. It varies from 0.266 GHz to 3.6 GHz.

In addition, the Intel Celeron does not benefit from hyper-threading, a technology designed by Intel to double the number of physical cores, thus increasing the performance of the processor, especially for multitasking.

The Celeron also does not benefit from the Turbo Boost technology found in the processors of the Intel Core range, which increases the frequency of the processor to boost its power when the system is stressed.

Finally, compared to other processors such as the Intel Pentium and the Intel Core, the Celeron has a lower cache memory , making the processor less efficient.

An affordable and economical processor

But as a low power processor, the Intel Celeron processor has the advantage of being energy efficient. It allows desktops to consume less power and provides better battery life for laptops.

It is also the cheapest of the Intel processors, and allows users with a limited budget to access the computer tool. This is what it was invented for by the leader in microprocessors.

And although it is an entry-level processor, the Intel Celeron is suitable for many purposes.

What are the uses of the Intel Celeron?

Due to its characteristics and functions, the Intel Celeron processor is intended for basic computing use. He is very comfortable in internet browsing, word processing, video broadcasting, or even editing photos. On the other hand, it will be much less so for all more advanced multimedia applications, such as 3D creation software, video editing, or more resource-intensive games.

It will also allow you to make considerable savings. There is, in fact, no point in spending money on a more powerful machine that you have no use for.

On the other hand, if you aspire to evolve and to diversify your use of the computer, in particular towards multimedia or multitasking, more resource intensive, it is better to anticipate by opting for a more efficient processor , like the Intel Pentium, for example, to stay in reasonable prices.

How to determine the power of a Celeron?

To know the power of a Celeron processor, you can decipher its reference, which is made up of a series of 3 or 4 digits, preceded by a letter.

The letter or the number of thousands corresponds to a series of Celeron processors, while the last three are significant of the positioning of the processor in this series, in terms of power and functionality. The higher the number, the better the processor is.

Thus, the Intel Celeron G550 offers better performance than the Celeron G540.

What is the difference between Intel Celeron and Intel Pentium?

When presenting the various Intel processors, the Celeron and the Pentium often go hand in hand because they have many similarities. However, it is useful to remember their differences in order to know the CPU that best meets your expectations.

what is a celeron processor good for

The Intel Celeron invented in 1998 and the Intel Pentium invented in 2000 are two entry-level processors created by Intel to meet the expectations of low-budget users.

Although based on the same architectural core, the Celeron processor is distinguished by lower functionality and performance compared to the Pentium.

Cache memory

Generally speaking, the Pentium has a larger cache memory capacity than the Celeron . The cache memory is what stores the data most often used by the hard drive, thus reducing access to RAM. So the larger this cache memory, the more efficient the processor.


The faster Pentium processor achieves a clock speed that can be twice that of the Celeron which does not exceed 3.6 GHz.

Embedded technology

In addition, some versions of the Intel Pentium take advantage of Hyper-Threading technology, like the Pentium G4560 which therefore has two cores but four threads allowing it to manage several tasks at the same time and to gain in reactivity. This is not the case with Intel Celeron processors.

The price

Less efficient but quite satisfactory for a basic use of the computer tool, PCs equipped with the Intel Celeron are less expensive than those equipped with a Pentium processor.

To conclude, the Intel Celeron is a good option if you have a limited budget and your computer use is reduced to office automation, surfing the Internet, managing your emails, or watching videos. . Otherwise, opt for a more efficient processor such as the Intel Pentium or the Intel Core i3!
