Difference between Pentium and Celeron with table

We explain the difference between Pentium and Celeron with table. The difference between Pentium and Celeron is that Celeron is a less powerful and cheaper alternative version of Pentium. Despite this, both processors deliver astonishing performance and value at affordable prices.

Originally founded on July 18, 1968, Intel is the world’s largest and most successful manufacturer of semiconductor computer circuits. In the past two decades, it has been one of the most successful companies in the microprocessor business.

A processor or microprocessor is a small computer chip whose basic job is to receive input and provide output, that is, it performs all the calculations associated with computing.

Pentium is a microprocessor that has four different versions, that is, Pentium to Pentium 4, each one more powerful than the previous one. 

On the other hand, Celeron does not have many versions and is designed specifically for low-cost PCs.

What is Pentium?

Pentium or Intel Pentium is part of a family of x86 microprocessors. It was originally a replacement for the 80486 processor and in 1993 the first processor of the P5 family (586), called the Pentium, was introduced.

Compared to 80486DX (3.1 million), Intel processors had speeds between 60 MHz and 300 MHz, a 64-bit data bus, and 1.9 million more transistors.

The word Pentium comes from the Greek word for “five.” The name is used because it is the fifth processor on line 80×86.

Followed by the first processor in 1993, Intel introduced the Pentium Pro in 1995. It became the first to contain an integrated high-speed level 2 memory cache with its own bus.

After that, Intel has evolved and released various P6 chips. By the end of the 2000s, it had introduced 4 powerful Pentium chips.

Intel Pentium processors are low-cost classic chips for entry-level PCs. The latest processor with Intel 32-bit Architecture (IA-32) is Pentium 4. It is the longest service family produced by Intel, even above the Celeron family.

Bus refers to the communication channel between other devices and the processor. The bus speed indicates the speed at which data can enter and exit the processor box.

The fastest bus speed for Pentium is 1,066 MHz. This means that the Pentium processor communicates with other devices in the computer, such as keyboard, hard disk, and so on. Too much faster.

Pentium III processors come with 512 KB of L2 cache memory and are based on a 133 MHz system bus. It supports multiprocessing and hyperthreading. Also, the fastest processor in the Pentium line has a 3.8GHz clock speed.

What is Celeron?

The first Celeron-based CPU was based on the Pentium II design. Most of its processors are based on Pentium II / Pentium III cores. Although, the latest chips come in Pentium 4. Celeron is the second least dominant processor in the Intel family.

Compared to Pentium processors, Celeron is a less powerful version. It is designed primarily for inexpensive personal computers.

Most Celeron processors run at speeds of 1.4 GHz or less. Celeron is low-end IA-32 and x86-64 chips designed specifically for low-cost PCs.

Comparing it to Pentium again, Celeron chips have somewhat lower performance along with low cache memory.

When it was based on the Pentium II design, it had a lower bus and smaller cache, but over time, Celeron processors have moved towards the Pentium III and Pentium 4 design. These chips are cheaper than Pentium processors.

Celeron processors use a 400MHz bus and come with 128KB of cache memory. It is designed for a motherboard that uses a 66MHz system bus.

The faster Celeron processor is clocked at 2.8 GHz and does not support multiprocessing or hyperthreading.

Main differences between Pentium and Celeron

  • Pentium is an extended family of x86 microprocessors, while Celeron is the lower-end Intel family of IA-32 and x86-64 chips.
  • The fastest processor in the Pentium line has a clock speed of 3.8GHz and the fastest Celeron processor has a clock speed of 2.8GHz.
  • Pentium processors support multiprocessing and hyperthreading and Celeron does not
  • The fastest bus speed for a Pentium is 1,066 MHz with 512 KB of L2 cache memory and the fastest bus speed for a Celeron processor is 400 MHz with only 128 KB of cache memory
  • Celeron chips are cheaper than Pentium chips.

Final Thought

You can see how Intel has produced Celeron and Pentium. But it was made with the intention of replacing Pentium. They are intended to occupy the market side by side, depending on the market preference and price. 

Although Celeron is less powerful than Pentium, both provide excellent services, performance, and are inexpensive.

Both chips are produced by Intel in the hopes of making semiconductor memory practical and affordable for everyone. Intel is booming day by day with its inventions and keeping its customers satisfied.

Entry-level personal computers have only been so amazing because of Intel’s two processors: Celeron and Pentium. They are affordable, fast, and amazing to use. People can access it without reducing PC performance. Pentium and Celeron
