Pentium 4 vs Pentium d: Difference and Comparison

Processors are a crucial aspect of our daily lives in the technologically driven era. However, the differentiation between these processors may not be an easy task.

Pentium 4 and Pentium d are two types of processors from Intel with varying functions and properties. 

Key Takeaways

  1. Pentium D processors are dual-core, providing enhanced multitasking capabilities compared to the single-core Pentium 4.
  2. Pentium D has a higher power consumption and heat output than Pentium 4 due to its dual-core design.
  3. Pentium 4 offers Hyper-Threading technology, allowing it to process two threads simultaneously, while Pentium D lacks this feature.

Pentium 4 vs Pentium d

Pentium 4 was based on the NetBurst architecture and used a 20-stage pipeline design, allowing it to achieve high clock speeds. Pentium D was a dual-core processor family that was introduced in 2005 as a successor to the Pentium 4. Pentium D processors were based on the Smithfield architecture.

What is Pentium 4?

Pentium 4 refers to a series of single-core CPUs. The manufacturer of Pentium 4 is Intel. Pentium 4 has easy operation on desktops, laptops, and entry-level servers.

The Pentium 4 processors were in circulation from 20 November 2000 till 8 August 2008. The architecture of Pentium 4 is NetBurst microarchitecture. 

The predecessor of Pentium 4 is Pentium III, and the successor of Pentium 4 is Pentium D. The introduction of Pentium 4 had mixed responses from the audience.

There was a dislike among developers for Pentium 4 because it posed a new set of code optimization rules. As expected, however, the new Pentium 4 outperformed the Pentium III in various aspects. 

The processors of Pentium 4 consist of an integrated heat spreader. The heat spreader ensures that there are no significant damages when mounting and unmounting cooling solutions. The bus speed of Pentium 4 is 533 MHz.

The processor base frequency is 2.80 GHz. In addition, there is no provision for an FSB parity.  The Pentium d processor allows for the provision of running multi-threaded applications.

The double-core model is ideal for the operation of both the client and server processes.

The VID voltage range of Pentium 4 is 1.340V-1.545V. The TDP is 68.4W. The package size of the processor is 35 mm*35 mm.

However, Pentium 4 doesn’t have turbo boost technology, hyper-threading technology, virtualization technology, idle states, and enhanced intel speed set technology. Thus, there are some advantages and disadvantages to the processor.

What is Pentium d?

Pentium d refers to a series of double-core CPUs. The Pentium d processor came into being on 25 May 2005. However, Pentium d was discontinued on 8 August 2008. The manufacturer of Pentium d is Intel.

The architecture of Pentium d is NetBurst microarchitecture. There are several practical applications of this model of Intel.

The Pentium d processor allows for the provision of running multi-threaded applications. The double-core model is ideal for the operation of both the client and server processes.

In addition, Pentium d provides services like transcoding of video and audio, photo and video editing, ray tracing, and rendering. 

The processor base frequency of Pentium d is 3.40 GHz. The bus speed of Pentium d is 800 MHz. The TDP of Pentium d is 95W. The package size of Pentium d is 37.5mm*37.5mm.

In addition, it offers an idle states provision as well as Enhanced Intel SpeedStep Technology. Thus, there are a multitude of advantages offered. 

Since Pentium D has a double-core processor, it consumes significantly more energy. Consequently, the Pentium d has a high heat generation, adversely impacting its functioning.

The heat generation, therefore, necessitates the installation of a third-party cooling system to prevent any major damage.
