Difference between Dual Core processors and Core 2 DUO processors

In this digital world when everyone is busy with their business life and mainly when in current scenario Information Technology (IT) plays vital role, there comes device computer without which thinking about current or next digital world is impossible. But we know Central Processing Unit (CPU) is brain of computer which is responsible for processing or execution of any task and generate result. Here comes performance of processor as everyone wants to get the actual output/result with in fraction of time. So there speed and performance of processor matters more.

In general if we will see also when anyone goes to any computer shop to buy any new computer and researches lot about device processor just to be sure about the performance of computer which in turn depends on device processor. So processors have great impact on device so it is considered as one of important element or part of computer. That’s why with respect to time and with advancement of technology new types of processors have also started evolving. So in below two different types of processors have been analyzed based on different factors like performance, memory architecture and overclocking of processor etc.

A dual-core processor is type of Central Processing Unit (CPU) that has 2 complete execution cores. Dual core has become similar with Intel Pentium Dual Core, where the Core 2 DUO are series of dual-core processors invented by Intel.

1. Dual-core Processor :
Computers were originally launched to be able to solve mathematical problems. In earlier times these computers were slow to process data and could only run one at a time, which means another process had to wait for one operation to become over, before another operation could begin. These were known as single core processors. Demand for faster technology now a days required that the processor companies make faster processors which have higher clock speeds. When basic factor of performance i.e., maximum clock speed was achieved, then the manufacturers focused to increase performance of their products by adding more cores to single chip. These became known as multi-core processors and which also include dual core, quad core, hexa-core and octa-core processors.

It has combined power of two processors as it has two complete execution cores. Dual-core processors are well-suited for multitasking as their caches and cache controllers onto single chip.



Cores have an independent interface to the front-side bus. Each core has its own cache memory. This allows OS (operating system) to have sufficient resources to handle intensive tasks in parallel.

2. Core 2 DUO Processors :
Core 2 Duo comes under series of dual-core processors which are invented by Intel. Intel named its series as Pentium Dual Core during starting of dual core processors, which referred to companies dual cores. Number of up-gradation and improvement in Intel first series processors resulted in them calling their processors as Core 2 Duo, with duo hinting two processors that are found on processor. These are known as 1st generation of dual processors. For example AMD refers to its dual core processors as X2.

There were simply 2 Pentium 3 processors on single chip in Core 2 Duo. With advancement of processor technology by making it faster and better, company decided to differentiate it from their first generation processor by naming them as Core 2 Duo where this  2 refers to 2nd generation of processors.



Difference between the Dual Core processors and Core 2 DUO processors :

S.No. COMPARISON DUAL CORE PROCESSORS CORE 2 DUO PROCESSORS
01. History It comes under Multi core processor. It is the extensive version of Dual core processor.
02. Performance In comparison with previous processors, Dual core is better than all. Core 2 duo has better performance than Dual core as it has better overclock ability than Dual core.
03. Cache Memory In Dual core processor we have 3 MB of L2 cache memory. In Core 2 Duo processor we have 6 MB of L2 cache memory.
04. Overclock In this processor we can overclock the CPU up to 3.12GHz (approximate value). In Core 2 Duo processor we can overclock it up to 4.0GHz.
05. Cost It costs up to 4899 (2.8GHz) according to speed and other specification in current market. Core 2 Duo costs up to 1396 (4.0GHz) according to speed and other specification in current market.
06. Execution It has two complete execution cores. Due to high clock speed/overclock ability, it can execute multiple task parallelly.
07 Example Intel G530 Dual Core. Intel Core 2 duo T8100.
