Difference Between Intel Atom vs. Celeron vs. Pentium CPUs

Written By Farhan Max

Intel has been reigning supreme in the CPU market for almost half a century with thousands of marvelous processors.

Yet naming the CPUs was a challenge for Intel, and undoubtedly they failed as the names tell nothing about a processor.difference-between-intel-atom-vs-celeron-vs-pentium-cpus Intel has three lineups for the low-end processor segment: Atom, Celeron, and Pentium. It is confusing to choose a CPU from these vast alternatives.

However, this article will eliminate all the confusion and assist you in selecting a suitable processor.

What’s the Difference Between Atom, Celeron, and Pentium CPUs?

Intel Atom is a tiny processor that uses ultra-low voltage and is compatible with portable devices, such as mobile, ultrabooks, and tablets. Celeron is a low-budget series that mainly focuses on laptops and mobiles. Pentium is close to the Core i3 series and provides a smoother experience.

If you want to compare the Atom, Celeron, and Pentium processors based on performance, the sequence will be Pentium > Celeron > Atom.

Note: Intel 7th gen Pentium processors have achieved about 95% performance of Intel Core i3 processors.

Intel builds Pentium or Celeron processors on two different technologies: Atom-based and Core-based.

To find out whether the processor is Atom-based or Core-based, look at the model of your chip. If your Pentium or Celeron processor has N and J in front of the model number, it’s Atom-based. On the other hand, if the model number has G in the front of the name, it’s Core-based.

Consider the following discussion to understand the differences between the Atom vs. Celeron vs. Pentium CPUs.

1. Intel Atom Processor

Though Intel is the top processor manufacturer for almost all devices, it was far beyond the enormous mobile processor industry.

In 2008, Intel introduced its new processor, Atom, to beat the mobile processors manufacturers, such as Qualcomm Snapdragon, Apple Bionic, and Samsung Exynos.

Unfortunately, Intel could not cope with other mobile processor manufacturers and discontinued the Atom processor lineup in 2016. The most valuable product that came with the Atom processor was a netbook.

But with time, the netbooks were replaced by other tablets and Chromebooks because of the affordable and compact designs.

However, Intel is still making Atom processors for Servers, Cellular Infrastructure Applications, and IoT devices.

2. Intel Celeron Processor

If you are looking for an efficient and ultra-budget computer processor, the best available option is the Intel Celeron Processor.

It is the low-end processor you may find available in the Intel processor lineup. Celeron processors are mainly dual-core CPUs without any enabled hyperthreading. A Celeron processor consists of two cores and two threads.

Intel Celeron CPUs have two different lineups for desktops and laptops. G series processors are for Desktops, and the N series processors are for laptops.

The desktop-based Celeron processors are comparatively more powerful than the laptop-based Celeron processors. Additionally, the desktop-based Celeron processors offer much higher TDP (Thermal Design Power) in watts.

Consider the following table for the most affordable and powerful Celeron CPUs:

Processor NameBenchmark ScoreNoteTypeTDPConfiguration

Intel Celeron G59052846Desktop-based flagship CPUDesktop58W2 Core, 2 Thread (3.50 GHz)

The table above represents the performance data of most recent and popular Celeron processors.

Even the weakest Intel Celeron N4020 is much more powerful than the Intel Atom processors in terms of performance.

Caution: Remember, just because a Celeron CPU is powerful and the series’s flagship doesn’t mean it is popular.

So, when comparing any Celeron CPUs with other models, you should pick a model that is available for comparison. For example, the Intel Celeron N5100 CPU is the most powerful in the Celeron series but is infrequent and unsuitable for comparison.

Instead, you can pick the  Intel Celeron N4020 CPU for a better comparison result.

Let’s quickly look at the Celeron CPUs’ usage:

  • Basic web browsing
  • Watching Movies and TV Shows
  • Basic Word, Excel, and PowerPoint use
  • Emailing
  • Social media use

If the above usage meets your requirements, you can choose the most suitable one without hesitation. Otherwise, keep scrolling to find the best Pentium processor for you.

3. Intel Pentium Processor

For basic productivity tasks, the perfect choice is the intel Pentium processor series.

The Pentium processor series is far behind the next Intel Core i3 lineup. But if you want a CPU that can effortlessly handle most basic tasks with light gaming, the Pentium series is way better than the Celeron processor.

While the Celeron processors are laggy and lack performance, the Pentium processors offer a smoother performance. The latest Pentium CPUs are also good for gaming.

Before the Intel Core series, the Pentium processors were Intel’s top-tier. Intel divided the Pentium series into two lineups: Pentium Silver and Pentium Gold. It makes the Pentium lineup more complex.

Pentium Silver Processor

Intel Pentium Silver CPU is the modified version of the Celeron processors. Some of them even belong to the same Intel Gemini Lake generation.

The Pentium Silver and Gold series was created for a different product category. The Silver series comes with pre-built devices. So, you cannot find a Silver series processor on a shelf to buy separately.

Check the following table for the latest Pentium Silver CPUs:

Processor NameBenchmark ScoreProcessor TypeTDPNotesConfiguration
Intel Pentium Silver N60053224Laptop/ Mobile10WFlagship CPU4 Core, 4 Thread (2.0-3.30 GHz)
Intel Pentium Silver N50302637Laptop/ Mobile6WPopular CPU4 Core, 4 Thread (1.1-3.10 GHz)

Pentium Gold Processor

The Pentium Gold series processors are very close to the Core i3 processor. They even share the same design architecture.

But the Gold series offers fewer cores, clock speed, and TDP compared to the Core i3 processors. It makes the Gold series more power efficient and suitable for mobile and tablets.

Quick Note: The Pentium Gold series is not superior to the Intel Silver CPUs. Sometimes, the Gold series is even worse than the Silver series, particularly in the mobile segment.

However, the Gold series is superior compared to the Atom, Celeron, and Pentium Silver for the desktop CPUs. It is still the best-performing CPU than the others.

Consider the following table for the latest Pentium Gold CPUs:

Processor NameBenchmark ScoreProcessor TypeTDPNotesConfiguration
Intel Pentium G64004155Desktop58WPopular2 Core, 4 Thread (4.0 GHz)
Intel Pentium G66004396Desktop58WFlagship2 Core, 4 Thread (4.2 GHz)

Pentium Gold series uses hyperthreading technology that makes the processor more efficient and helps to save power.

Pentium Gold 6405U CPU (designed for laptops) is inferior to most Pentium CPUs and even some mobile-grade Celeron CPUs.

Let’s have a look at the Pentium CPUs’ usage:

  • Multitasking (You can open different applications or multiple browser windows at a time)
  • Basic gaming (League of Legends, Minecraft, Need for Speed, etc.)
  • Productivity tools use (Basic editing)

Recommendation: For an entry-level desktop build, desktop-based Intel Pentium Gold processors are highly recommended.

Intel Atom Vs. Celeron Vs. Pentium Processors Performance Benchmarks

Benchmark is a computational process that runs a set of computer programs for measuring the comparative performance of a processor. The benchmark clearly shows the processor’s performance to understand the capability compared to other processors.

Consider the following image that shows the Passmark score of various Intel processors. I have also added a Core i3 CPU for better understanding.


The image above clearly shows the Passmark scores for Intel Atom, Celeron, and Pentium processors. Besides, you should also check the processor’s specifications to understand the differences better.

There is not very much difference between the Celeron and Pentium N series processors. However, the Pentium processors have an advantage with the clock speed.

On the other hand, the Atom processors are far behind compared to the Celeron and Pentium N series processors. Since these are all dual-core CPUs, you should know how good dual-core processors are in terms of gaming.

Which Intel CPU is Right for You?

The best Intel CPU is highly dependent on your use cases. If you are looking for a CPU that offers the best battery life, lower heat dissipation, and less performance, then the Pentium Silver (Pentium/Celeron N and J series) is the right choice.

In case you need a CPU for multitasking with high performance, then the most suitable CPU for you is the Pentium G series.

However, not every Pentium G series processor is powerful enough compared to Celeron CPUs. For instance, Intel Pentium Gold 6405U is a laptop-based CPU. It is inferior to the Pentium Silver CPUs and some mobile-grade Celeron processors.

So, while choosing the best CPU for your laptop or desktop computer, you must find the use cases first, and then you can efficiently pick the right one from the vast CPU models.
