Pentium D vs Pentium Dual Core: Difference and Comparison

Pentium microprocessors are the most affordable and user-friendly by Intel. They’re a great range of inventions. With each invention, they focus on an effective evolution. Pentium D and Pentium Dual-core are two such popular discoveries in the market.

Pentium D was not very compatible in the long run. Due to this, within two years, Intel came up with its step-up version and named it Pentium Dual-core. Let us dive into the article to learn about their features.

Key Takeaways

  1. Pentium D is an older, single-core processor with hyper-threading, while Pentium Dual-Core is a more recent, true dual-core processor.
  2. Pentium Dual-Core processors offer better performance and energy efficiency than Pentium D processors.
  3. Pentium D processors are less suitable for multitasking, while Pentium Dual-Core processors handle multiple tasks more efficiently.

Pentium D vs Pentium Dual Core

Pentium D is an x86 – 64 microprocessor built for P4 architecture which has a very high clock speed and its P4 cores are stationed beside each other. Pentium Dual-core is a processor that is used for core architecture which has a low clock speed, shares its L2 cache, and is executed parallelly.

Pentium D was the first dual-core processor from Intel. It was introduced in the year 2005. During that time, AMD was in high demand in the market with its dual-core feature.

So basically, Pentium D was introduced to compete with it. It is based on the P4 architecture.

On the other hand, Pentium Dual-core was the greatest step up in the history of processors. It was introduced in the market two years later and was indeed a huge success.

It overcame all the problems faced during the era of Pentium D. It has a very high speed and is compatible and user-friendly with the system.

What is Pentium D?

The construction is quite simple. It is designed by setting two P4 cores side by side. However, they work separately and are not linked to each other. They do not share any common features are assigned with their specific functions.

It has a TDP between 95W to 130W, which is considered very high. However, each of them has the same cache size of 2MB. Pentium D can reach a clock speed of up to 3.7 GHz.

However, it could not make a huge success in the market. The motherboard that supports Pentium D must be able to cope with the high-power requirement.

For the safety of the system, it is suggested to install a cooling system. This ensures better, safe, and long-term work.

There were a lot of comebacks that needed to be overcome. Certain features were being discovered that were not compatible with the system.

Hence it was not as successful as the makers expected it to be. Due to this failure, it was not able to compete with AMD for a long period.

However, a huge amount of heat is produced even at a low clock speed. This is one of the disadvantages and is harmful to the system. It also consumes a huge amount of power.

Pentium D processors are indeed power-hungry. It does not include hyper-threading.

What is Pentium Dual-Core?

Pentium D is based on core architechture. It is adapted to the best qualities and amazing features. This invention swiftly overcame all the flaws and challenges faced by the Pentium D.

It outperformed Pentium D to a great extent and was a very successful introduction in the market.

As the name suggests, it has two cores. It executes in parallel and shares the same memory. It was introduced in early 2007 and is available in an affordable price range.

It comes with a lot of exciting features. The enhanced power technology is probably the best adaption in Pentium Dual-core.

It comprises an external bus of 533/800 MHz. It has Intelligent Power Capability and comes with an SSE3 instruction set. It has a lot of advanced features to be safe for the system. They include Dynamic Power Coordination and Advanced Thermal Manager.

It produces the minimum amount of heat. It was a great achievement since it was one of the main problems in Pentium D. However, it is not designed to run at a very high speed.

It can reach a maximum speed of 3 GHz. Although this is a disadvantage, the other features make up for it pretty well. It has a TDP of 64W.

Main Differences Between Pentium D and Pentium Dual Core

  1. The main difference between Pentium D and Pentium Dual-core lies in their architecture. Pentium D is based on P4, whereas Pentium Dual-core follows the dual architecture.
  2.  Next comes power consumption. Pentium D consumes a high amount of power. Pentium Dual-core consumes comparatively less power. It is surely one of the best features.
  3. Pentium D has a higher clock speed as compared to Pentium Dual-core. Pentium Dual-core has a lower clock speed as compared to Pentium D.
  4. Coming to cache, Pentium D has a non-shared L2 cache, whereas Pentium Dual-core has a shared L2 cache.
  5. Pentium D produces a great amount of heat which is harmful to the system. Pentium Dual-core is specially designed to produce less amount of heat.
