A dual-core CPU combines two independent processors and their respective caches and cache controllers onto a single silicon chip, or integrated circuit.

-DJ Craig

:

A dual core processor is a CPU with two separate cores on the same die, each with its own cache. It's the equivalent of getting two microprocessors in one.

In a single-core or traditional processor the CPU is fed strings of instructions it must order, execute, then selectively store in its cache for quick retrieval. When data outside the cache is required, it is retrieved through the system bus from random access memory (RAM) or from storage devices. Accessing these slows down performance to the maximum speed the bus, RAM or storage device will allow, which is far slower than the speed of the CPU. The situation is compounded when multi-tasking. In this case the processor must switch back and forth between two or more sets of data streams and programs. CPU resources are depleted and performance suffers.

What is the advantages or dis advantages of dual core processors?

Dual Core Processors give you the advantages of twice the speed of a normal processor, however both processors still need to communicate between one another.


What is the difference between dual core and dual processors?

Dual core is a technology through which dual processors can be realized on a single chip of Motherboard with a single socket by fusing together two processors,so that the cost of mounting two processors on two different Moterboards is reduced,so the high efficiency is realized with low cost .


What is meant by dual-core and quad core device?

They're essentially devices that have multiple processors on a single chip. Dual-cores have two processors, quad-cores have four.


When did the multiple-core or dual core processors become available?

Dual-core processors were released to the general public in 2005 by both AMD and Intel. Quad-core processors were released two years later in 2007. Hexi-core (6) came out in 2010. There are currently 8 and 16 core processors available for servers, although home PC Octa-cores are not available.

Is an Intel Celeron processor a dual core processor?

There are Celeron dual core processors today. However, just because you have Celeron processor, it does not mean your Celeron processor is a dual core processor. The easiest way to tell is to look at the Intel sticker on your computer. If it says "Dual Core," then it is dual core. If it does NOT say "Dual Core," then it is not dual core.


What are the advantages of dual core?

Dual Core Processors give you the advantages of twice the speed of a normal processor, however both processors still need to communicate between one another.

How many core processors are contained in a modern processor?

Processors were originally created with a dual-core processor, which remained the norm for a long period of time. However, multi-core processors are now using up to ten processors.


What is the difference between Dual Core and Core 2 Duo?

'Dual Core' is a generic term for processors with two cores. Core 2 Duo is a dual core processor brand designed by Intel.


What are the specifications of the Intel Core 2 processors?

The specifications of the Intel Core 2 Duo processors are Intel dual-core technology, Enhanced Intel SpeedStep, Execute Disable Bit, and Intel 64 architecture. Intel Core 2 Extreme processors are similar but have Intel Virtualization Technology in place of dual-core technology.


Will a dual-core processor work with an Intel 865G motherboard?

No. The Intel 865 chipset doesn't support dual-core processors.


Compare multi-core and dual core?

"Dual core" implies that there are two separate instruction execution units placed on a single "die." Some use shared components, such as cache, while others have two full processors, including all sub-components. All dual core processors could be considered multi-core (which simply means multiple "cores" or "processors"). However, a tri-core or quad-core is also a multi-core. Therefore, all dual cores are multi-cores, but not all multi-cores are dual cores.
