Difference Between Celeron, Centrino And Pentium

Want to find out the difference between Celeron, Centrino, and Pentium?

Don’t worry, this is the right place. In this article, we will learn about the differences between these three CPUs.

However, before examining their differences, it will be important to briefly examine these CPUs on an individual basis.

A lower extremity of 1A-32 and X86-64 is best referred to as Celeron. This is the correct name that most Intel brands use to address this microprocessor.

The Intel Celeron was launched on the 15th April 1998 with a performance CPU clocks rating about 266 MHz to 3.6 GHz as well as a speed of about 66 MHz to 1333 MT/s.

If you are using A-32 software, you will enjoy working with a Celeron CPU, although they work less by clock speed compared to a flagship Intel CPU line.

Some types of Celeron CPU have less cache or disabled modern functionality that makes its performance variable. But on the other hand, there are Celerons with amazing performances.

Some of the models of Celeron family include Covington core 250 nm launched in August 1998, Mendocino core 250 nm launched in March 2000, Coppermine core 180 nm launched in March 2000, Willamette core 180 nm launched in October 2001, Tualatin core 130 nm launched in October 2001 and so forth.


Intel has built Centrino technology as a marketing platform. It’s a small tech set in a CPU, main card chipsets, plus the wireless interface that’s in a computer system.

Moreover, this technology aimed to provide wireless connectivity as well as for better performance and use of the long battery.

Centrino’s research and development was conducted in Haïfa, Israel. In 2003 the first Centrino platform was launched, known as the Camel.

Some models of Centrino technology in the first generation include Intel Pentium M processor with a Banias code name and have a mega transfer speed of approximately 400 GHz per second.

There is also a bus outlet on the front side.

Additionally, we have the Intel 855 series of chipsets, with a code called Odem sometimes called Montara. Finally, Intel Wireless 2100 or mini-PCI 2200 with Wi-Fi adaptor.


The name Pentium stands for «five», according to the Greek language. This was before the conventional naming by Intel CPU using 80×86 (8086×80486) Numerical digits.

The first Pentium technology was completed and launched on March 22, 1993. Subsequently, Intel rolled out Pentium II and Pentium III. It is a microprocessor that is intended to be suitable for the x86 series.

Around 2007, the Pentium teams were split into two.

We have the Pentium silver that was targeted for low-power computers and we have the Pentium gold that was targeted for the desktop that uses the input level.

Some of the generations of Pentium include Pentium P5, Pentium P54C, Overdrive P54CS, Pentium MMX P5, Pentium overdrive MMX P55C, and the list goes on.

Variation between Celeron and Pentium

We are going to check some differences in terms of speed, memory capacity, efficiency, and affordable rate.

  • Speed

When it comes to clock speed, Celeron is not faster than the Pentium CPU. This is because Celeron microchips depend on Pentium II and III respectively.

Therefore, a Celeron clock speed at the range of 1.4 GHz. The fastest speed of the Celeron clock is between 1.6 and 2.8 GHz.

But as far as Pentium goes, the fastest clock speed is about 3.8 GHz.

  • Memory capacity

In terms of memory capacity, Celeron chips have a smaller cache than Pentium 4 chips.

A 400 MHz bus of a Celeron has a retention of about 128 kB, while a Pentium 4 chip memory capacity is four times that of a Celeron, with about 512 lb.

Though the speeds of both CPU are comparable, that’s because a Celeron has an L2 cache on the microchip which a Pentium II doesn’t have, and this affects the carrying out of a computer system.

In this respect, a Celeron CPU is appropriate for navigating and word processing.

But if you are planning to make use of a computer higher than the above uses, it will be best you opt for Pentium processors.

  • Efficiency

Among all Intel’s CPU, Celeron is the least powerful CPU.

This is because the computer system has the least expensive chips.. Whereas a Pentium CPU has high efficiency of about 32 bits and it is always the most durable CPU.

  • Cheap Cost

It is less expensive to purchase Celeron CPU than Pentium II-4 respectively This is because of the higher velocity of the Pentium and the memory capacity as we mentioned above.

Variations Between a Pentium and Centrino

Pentium CPU are usually the best for use in the marketplace and are suitable for Intel laptops and desktops.

But on the other hand, Centrino CPUs serve as the basis for only laptops produced by various manufacturers such as Lenovo, HP, Asus, Panasonic, and so on.

A Pentium is all about the processor in a computer system, whereas a Centrino is characterized by three components, which consist of a chipset, CPU, and wireless board. Although Intel has made some changes on these three components over the years, that’s why Centrino laptops can carry Pentium CPUs.

It takes time for a Pentium CPU to run; the latest one was the Clarkdale that shares similar features with the i3 kernel. Contrary to Centrino who has always been in the development of new CPU since its introduction in 2003.

Variation Between Celeron and Centrino

As previously stated, a Celeron is a combination of an Intel CPU line.

But a Centrino on the other hand is a combination of the CPU, the network adapter, and some chipsets. When it comes to speed, a Celeron has a slower processing speed compared with the Centrino technology.

If the memory capacity is what you want between the two CPUs, then Centrino has a higher memory capacity than a Celeron.

These are some other variations between all these three CPUs, but the little we have provided can go a long way to widen your knowledge about a Celeron, Centrino, and a Pentium.

Whenever you want to get a computer system, you know which one is best to choose from.
