Intel is widely known as the best company in processor manufacturing. It was the company which introduced multi-core processors by using hyper threading. Check out difference between Intel Atom, Celeron and Pentium Processors.

The concept of multi-core processors has changed the universe of computers totally. Once, Intel Atom, Celeron and Pentium were the most successful products of Intel.

All of them are entry level processors. The price of them is also pocket friendly. Being entry level processors, they are not able to handle high end systems.

These are rarely used in this era. Through the names of the processor it is not possible to predict the quality or speed of the processors and the performing capability of them.

On the other hand, Intel has launched plenty of variants of these processors. It is very difficult to understand and mark out the differences among these three processors for a beginner.

So, in this article, we will briefly discuss all of them and will try to cover all of the important aspects of these processors. Check out difference between laptop and desktop processor.

Intel Atom Processor

Intel Atom Processor

Intel Atom is a very basic level processor. Intel has developed this processor at the very preliminary stage. The performing ability of Intel Atom is not good for this era.

Now, no one uses this processor in his PC. Some mobile manufactures have used it in their basic models. Intel has developed this processor to offer ultra low voltage solutions in some integrated devices like tablets, smart phones, etc.

One can also find this processor in some low configured notebooks. As we know, the notebook was the ancestor of the modern laptop. Notebooks used to be very slim and light weights, but they were not as powerful as modern laptops.

As the smart phone manufacturers started to develop their products, this Intel Atom processor started to be phased out. Intel lost its position in the mobile processor after the failure of this processor and companies like Qualcomm, MediaTek started to rule in the mobile industry.

For desktop and laptop, this is an era of Intel’s ‘i’ series processor. Almost in the similar way of ‘i’ series Intel had launched its Atom processors in the name of ‘x’ series. Intel Atom x3, Intel Atom x5, and Intel Atom x7 were the processors launched under the Atom series of Intel.

This is not made for use in laptops or desktops. It was placed in some smart phones and in some tablets. Asus had used this processor in some models of its Zenpad series. It was found in Asus Zenpad 8 and Asus Zenpad 10.

  • Intel Atom x5 Processor

This Intel Atom x5 again is not compatible in any laptop or in any desktop. It has been used in some tablets. Acer, the widely known tablet manufacturer, has used this Intel Atom x5 processor in its Acer Switch 10.1 device, which is a detachable and convertible laptop.

  • Intel Atom x7 Processor

This Intel Atom x7 has reached its popularity for Microsoft. Microsoft, a very common name in the universe of computers, used this processor in their Microsoft Surface Pro 3 tablet.

The processors which were launched by Intel under Atom series are totally phased out now. They were mainly used in smartphones and tablets, not in desktops.

Intel Celeron Processor

Intel Celeron Processor

Intel Celeron Processors are used in low configured laptops and desktops. There was a time when every budget friendly PC was equipped with an Intel Celeron Processor.

The TDP rating in Intel Celeron Processor is comparatively lower than Core Series or Pentium Series processors. The price of Intel Celeron Processor was also less than the others.

Having lower TDP ratings the Intel Celeron Processors generated very low heat and it was also very useful in laptops, as the battery can serve for a longer time.

This Intel Celeron Processor was very efficient in performing basic level tasks; such as browsing on the internet, using MS Office and other basic level applications.

Intel Celeron Processors also come in three variants; they are Intel Celeron N, Intel Celeron J, Intel Celeron G. All of them are different from one another in terms of clock speed, TDP ratings and in other perspectives.

  • Intel Celeron N Processors

Intel also provides many variants of this Intel Celeron N processor such as Intel Celeron N4000, Intel Celeron N4100.

  • Intel Celeron N4000 Processor

The Intel Celeron N4000 is a Dual Core processor and it is mainly used in mobiles. The TDP rating of this processor is around 6 Watts. Clock speed of this Intel Celeron N4000 is 1.1 GHz.

The processor’s performance is not up to the mark. It is a very entry level processor and it is also very energy efficient.

  • Intel Celeron N4100 Processor

This processor is a sequel of the previous one and it is developed from that one. This Intel Celeron N4100 processor is 41% more efficient than Intel Celeron N4000.

Intel Celeron N4100 processor is a quad core processor and quite a powerful one. It is also suitable for mobile.

The TDP rating of this processor is around 6 Watts and the clock speed of this Intel Celeron N4100 is 1.1 GHz. It is also found in some low configured budget laptops.

  • Intel Celeron J Processors

Intel Celeron J processors are very common in desktops. Intel Celeron J4005 processor is a very popular product of the series.

This processor has a TDP rating of 10 Watts. 2.00 GHz is the clock speed of this processor. A low configured PC usually comes with this Intel Celeron J4005 Processor.

  • Intel Celeron G Processors

The processors which come under Intel Celeron G series are relatively more efficient than the other processors of Celeron series.

Intel Celeron G4900 is almost 50% more powerful than Intel Celeron J4005 processor. It is the first processor of the series which is capable of handling high end tasks like gaming.

It is basically a dual core processor. The clock frequency of the processor is 3.1 GHz. The TDP rating of this Intel Celeron G4900 is around 54 Watts.

This Intel Celeron G4900 is 63% more efficient than Intel Celeron N4000, which was the basic model of the series.

The processors under the Celeron series of Intel are used to serve different fields. These processors are present in mobile, they are also used in basic level, and low configured PCs.

One can easily use Intel Celeron G4900 processor for performing high end tasks. So, through the Celeron series, Intel had introduced a broad range of processors.

Intel Pentium Processor

Intel Pentium Processors

In the Pentium Series Intel comes with a lot of variants. Intel offers Intel Pentium N, Intel Pentium G, Intel Pentium J, Intel Pentium Y, Intel Pentium U, Intel Pentium Silver, and Intel Pentium Gold.

So, it is very difficult to differentiate and choose the perfect processor for a casual user. Let us take a short overview of all of them.

  • Intel Pentium Gold G Processor

Let us take Intel Pentium Gold G5600 processor. This is a dual core processor. It is suitable to be used on a desktop.

  • Intel Pentium Gold Y Processor:

Intel Pentium 4415Y is a processor which is very commonly found in mobiles. This Intel Pentium 4415Y is the weakest processor that Intel has ever made.

Even Intel Celeron N4000, which we considered as the most basic level processor, is 4% more powerful than this product. Although this processor is placed under Pentium Series by the company, its performance is lower than any processor of Celeron Series.

It is found in tablets and in some notebooks which have low configuration. Microsoft is also using this processor in its Microsoft Surface Go.

This processor is just a slice better than the Intel Atom processors. Clock frequency of this processor is around 1.6 GHz.


Intel is widely acknowledged for providing the best desktop processors. All the three series mentioned at the title of the article are entry level processors.

It is very hard to find these processors in updated PCs. The differences among these processors are mainly in processing speed.

We have mentioned clock frequency in almost all the processors mentioned above. In this era of Intel i9 processors, these basic level processors are phased out.
