Difference Between Pentium and Celeron (With Table)

Pentium vs Celeron

The difference between Pentium and Celeron is that Celeron is a less powerful and a cheaper alternative version of Pentium. In Spite of this, both these processors give amazing performance and value at pocket-friendly prices.

Originally founded on July 18, 1968, intel is the largest and the most successful manufacturer of semiconductor computer circuits in the world. In the last two decades, it has been one of the most successful companies in the microprocessors business.

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

Pentium is a microprocessor that has four different versions i.e. Pentium to Pentium 4, each more powerful than the last.

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

When compared with 80486DX (3.1 million), Intel processors had the 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 meaning “five”. The name is used because it’s the fifth processor in the 80×86 line.

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

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

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

Bus refers to the communication channel between other devices and the processor. The bus speed states the rate at which data can enter and leave the processor case.

The fastest bus speed for Pentium is 1,066 MHz. This means that the Pentium processor communicates with other devices of the computer, like keyboard, hard drive, etc. much faster.

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

What is Celeron?

The first ever Celeron-based CPU was based on the Pentium II design. The majority 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 of the Intel family.

In comparison to Pentium processors, Celeron is a less powerful version. It is mainly designed for the budget-friendly value Personal Computers.

The majority of Celeron processors run at speeds of 1.4 GHz or less. Celeron is of 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 low bus and smaller cache but with time, Celeron processors have wandered to Pentium III and Pentium 4 design. These chips are cheaper than Pentium processors.

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

The fastest Celeron processor has a clock speed of 2.8GHz and it does not support multiprocessing and hyperthreading.


Main Differences Between Pentium and Celeron

  • Pentium is an extended family of x86 microprocessors whereas Celeron is the Intel Family of low-end 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 supports multiprocessing and hyperthreading and Celeron does not
  • The fastest bus speed for Pentium it is 1,066 MHz with 512KB of L2 cache memory and The fastest bus speed for a Celeron processor is 400 MHz with only 128KB of cache memory
  • Celeron chips are cheaper than Pentium chips.

 

Conclusion

It can be seen how Intel has produced the Celeron and Pentium. But it was made with the intention to replace Pentium. They are meant to occupy the marketplace side by side depending upon the preference and price tag for the same.

Though Celeron is less powerful than Pentium, they both provide great services, performance and are budget friendly.

Both chips are produced by Intel in a hope to make semiconductor memory practical and affordable for everyone. Intel is booming day by day with its inventions and are keeping their customers satisfied.

Entry level Personal computers have only been this amazing due to Intel’s two processors- Celeron and Pentium. They are affordable, fast and amazing to use. People can get access to it without lowering the performance of the PC.
