What Is the Difference Between a Pentium and a Celeron Processor?


Do you know how to identify one processor from another? Xia yuan/Getty Images

Two of Intel’s most popular microprocessors are the Pentium and Celeron. Here are the similarities and the differences:

  • Core: Both processors share the same basic dual-core architecture, with Celeron being the entry-level chip, and Pentium slotted above it. Both also have built-in graphics and support up to 128 GBs of RAM (computer memory).
  • Cache: The 2021 lines of both the Celeron and Pentium commonly have between two and four megabytes of cache memory (cache memory is where frequently used data is stored).
  • Clock speed: The 2021 Celeron line has options up to 3.6 GHz of clock speed, while Pentiums rank marginally faster, up to 4.3 GHz. Clock speed measures how fast a CPU can process data.
  • Bus speed: Both now also have very similar bus speeds with up to eight gigatransfers per second. (A bus is a circuit that connects one part of the motherboard to another. The more data a bus can handle at once, the faster it allows information to travel). Each processor can handle file transfers from things like USB drives quickly and effectively.

The main advantage Pentiums have over Celerons in 2021 is a feature called «hyper-threading.» This function allows the operating system to virtually «split» each processor core in two. So, a dual-core Pentium can effectively perform similarly to a quad-core. The manufacturer states that hyper-threading can boost computing speeds up to 30 percent higher during CPU-intensive tasks.


The Pentium used to be Intel’s high-grade processor, but it has since been replaced by the Core series, knocking it down to a mid-tier product. The Core line is intended for businesses and entrepreneurs and comes with all-around better stats. They have similar clock speeds to the Pentium chips but aren’t capped at two CPU cores. In fact, the top of the line comes with a whopping 18 cores, making it several times faster than the cheaper lines.

Core processors also have many more megabytes of cache memory, but the same bus speed as Intel’s other options. Additionally, they gain a «turbo boost» function, which allows the CPU to overclock itself automatically for short periods. Hyper-threading is also enabled, making the multi-core performance even more impressive. This speed does come at a price, with the most expensive Core units retailing at over $500, while a Celeron processor might cost under $100 and Pentium roughly between $100 and $200.

Celerons often come pre-installed in budget-conscience laptops, tablets and other compact smart devices. They’re just fine for that purpose, but for multitasking on a PC, the hyper-threading feature available on Pentiums will probably come in handy. If you regularly use resource-heavy programs like Photoshop, media production suites or modern 3-D games, you should opt for a multi-core CPU such as Intel’s Core processor or AMD Ryzen.


Intel Celeron Processor FAQ

Is an Intel Celeron processor good?

Celeron processors offer good value for their money as they are based on four Pentium cores, but with less cache memory. They can be particularly useful if you use Windows 8. 1 or 7. If you’re looking for a budget-friendly deal, Celeron processors are the right choice for small business and personal use.

Which is better: Intel Core or Pentium?

Intel is known to equip their Core brand with more powerful processors compared to the equivalent Celeron or Pentium models, even though they often use the same basic processor technology.

Which Intel Core is the best?

The AMD Ryzen 9 5950X with DirectX 12.00 takes the lead over Intel Core i9-10900K Processors with a 3DMark Physics score of 14133.

Is Core i3 better than Celeron?

Celeron and Core i3 both have the same number of cores. However, Core i3 has a 18GHz clock speed while Celeron has 1.1GHz making Core i3 the better choice.

Can I replace Celeron with i5?

You cannot replace your Celeron with i5 because Celerons belong to the LGA775 socket family while i5 technology is based on 1156 socket. Therefore, upgradation isn’t possible.

    Multi Core version of Cinebench R15 will load your system to the fullest, demonstrating everything it can. All CPU cores and threads are involved when rendering highly detailed 3D objects. Cinebench R15 is ideal for the new multi-threaded CPUs from Intel and AMD, as it is capable of using 256 computation threads. The Pentium 4 2.4A with a score of 20.99 does not win much in the multi-threaded Cinebench r15 benchmark. Slightly behind it is the Celeron D 331 gaining 18.99 points.

    Cinebench 15 (64-bit) Single-threaded test

    Cinebench Release 15 is the most up-to-date benchmark from Finns from Maxon. A complex 3D scene is rendered with a large number of light sources, objects and reflections. It tests the entire system: both CPU and video cards. For the CPU, the result of the analysis will be the number of PTS points, and for video controllers, the number of frames per second FPS. In this version of Single Core, 1 thread is used for rendering. The single-threaded test of the Pentium 4 2.4A processor in the Cinebench R15 program showed a result of 20.88 points, slightly ahead of the competitor. Having received 19With .04 points in this test, the Celeron D 331 is not far behind.

    Geekbench 4.0 (64-bit) Multi-threaded benchmark

    Geekbench 4 64-bit multi-threaded benchmark. Its broad OS and device support makes Geekbench benchmarks the most valuable to date. It’s Already In Geekbench 4 64-bit multi-core Pentium 4 2.4A received 491.63 points, which is slightly higher than the Celeron D 331. In this test, the Celeron D 331 scores its 456.95 points.

    Geekbench 4.0 (64-bit) Single-threaded test

    The current single-threaded version of Geekbench 4 for testing laptops and desktop PCs. The program, like its earlier versions, runs on systems: Mac OS, Windows, Linux. The Single-Core check uses one thread. For the first time in this version of the tester, both smartphones and tablets running Android and iOS operating systems are supported. The Pentium 4 2.4A scores the highest in Geekbench 4’s single-thread test with a score of 495.55 points, but not much ahead of the opponent. But the Celeron D 331 itself also showed a good score of 454.98 points, slightly giving way to the Pentium 4 2.4A model.

    Geekbench 3 (32 bit) Multi-threaded test

    Multi-Thread version of Geekbench 3 — allows you to make a big test on the «reliability» of your assembly and demonstrate how productive your OS is.

    Geekbench 3 (32 bit) Single-threaded test

    The 32-bit version of the benchmark loads only one processor core and one thread. The Geekbench multi-platform benchmark is usually used to evaluate the system under Mac, but it works on both Windows and Linux. The basic purpose is to check the efficiency of the CPU.

    Geekbench 2

    Geekbench 2 is currently out of date. There are almost 200 CPU models in our archive that have test results in this program. At the moment, there are newer options, the current 5v and 4v.

    X264 HD 4.0 Pass 1

    In fact, this is a practical test of system performance by transcoding HD files to the new H. 264 format or the so-called MPEG 4 x264 codec. The number of frames processed per second. is the result of the test. An ideal benchmark for multi-core and multi-threaded CPUs. This test is faster than Pass 2 because it renders at a constant rate. The MPEG 4 video processing speed of the Pentium 4 2.4A model is slightly higher than that of the Celeron D 331, and amounted to 5.92 fps. Celeron D 331 managed to score 5.43 FPS, slightly behind the first processor.

    X264 HD 4.0 Pass 2

    This is a slightly different, slower test based on video file compression. The final value is also defined in frames per second. As a result, we get a higher quality video file. It is important to understand that a very real task is being performed, and the x264 codec is used in many video programs. The same MPEG4 x264 codec is used, but the processing is at an inconsistent rate. Therefore, the results of the checks realistically reflect the performance of the system. During the encoding of the video file by the Pentium 4 2. 4A processor into the mpeg4 format, a processing speed of 1.26 Frames / s was obtained. While the Celeron D 331 is slightly behind with a score of 1.21 fps.

    3DMark06 CPU

    Written using the DirectX 9.0 library by the Finnish team Futuremark. CPUs are tested in two ways: the game AI does pathfinding, and the second test simulates the system using PhysX. Benchmark to evaluate the performance of the video system, and CPU. This benchmark is often used by gamers and fans to overclock the system and overclockers. Celeron D 331 showed itself a little faster in tests for game physics, pathfinding, gaining up to 285.87 points. The Pentium 4 2.4A also coped with these tasks, showing a good result of 278.34 points.

    3DMark Fire Strike Physics

    Approximately 200 processors on our website have 3DMark FSP data. It includes an arithmetic test that performs calculations in game physics.

    WinRAR 4.0

    The well-known data archiver. The speed of compression by the RAR algorithm was tested, for these purposes huge amounts of random data were used.
