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. |
Core 2 Duo Vs. Core Duo: Merom and Yonah square off
Intel has consistently impressed with its mobile CPUs.
The ageing Pentium M processor continues to be a solid foundation for laptops or desktop PCs (like the one in our ultimate quiet PC feature). The successor to the M processor — the Core Duo (codenamed Yonah), is a marvel of engineering that helped push the Centrino brand to new heights.
But what of the recently released Core 2 Duo range of processors, known in tech circles as ‘Merom’? Intel says they are up to 20 per cent faster than the current crop of mobile chips, but are they really as good as it makes out? Bored, disillusioned with the world and with a complete lack of anything better to do, we thought we’d break it down for you Crave readers.
The first thing you need to know about Core 2 Duo is that it’s not hugely different to the Core Duo. The key difference is that the fastest chips in the range, the T7xxx series, use 4MB of level 2 cache instead of the standard 2MB. The entry-level chips use 2MB, but all Core 2 Duo CPUs have the benefit of 64-bit EM64T support — though we won’t see the full benefit of this until Windows Vista rolls around.
For our test, we got hold of three laptops, two of which were from rockdirect. The first rock laptop uses a 2.33GHz Intel T2600 CPU — the fastest in the Core Duo range — while the second uses the new 2.13GHz T7400 from the Core 2 Duo family. The third laptop is a non-retail reference sample boasting a T7600 Core 2 Duo CPU. All three laptops use identical Intel 945PM chipsets, 1GB of DDR2 533MHz memory, and an Nvidia GeForce Go 7900 GTX graphics card.
To put them through their paces we ran the PCMark 2005 synthetic benchmark application to test their core performance ability. We also ran 3DMark 2005 to test graphics capabilities, and MobileMark 2005 to test features such as battery life and general mobile performance. We also tried out Cinebench 9.5, a free 3D rendering benchmarking tool, to put the systems through their paces.
According to PCMark 2005, there isn’t a massive difference between the three processors. The Core 2 Duo was around 5 per cent quicker, which isn’t worth writing home about.
Cinebench 9.5 showed more of a difference — the top-spec Core 2 Duo machine was 11 per cent faster than the Core Duo system in our single CPU test, and 8.5 per cent faster in the multi-CPU test.
Unsurprisingly, we didn’t spot much difference between the three processors during 3D gaming tests. They returned a nearly identical score in 3DMark 2005 and pretty much the same frame rates in F.E.A.R. As expected, the major bottleneck here is the graphics card. The Core 2 Duo processor is likely to be better than the Core Duo at running CPU-intensive games (such as those that display large numbers of non-playable characters on a screen simultaneously), but in most gaming situations the two CPUs are very similar.
The all-important battery life figures make for interesting reading. All three laptops lasted pretty much the same amount of time when playing a DVD movie and they ran out of juice within a couple of minutes of each other when browsing the Web using Wi-Fi. We can only conclude that this is a good thing, as the Core 2 Duo gives better performance without losing any battery life.
