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.

In computer processing, dual core processors are processors that feature two individual processing cores. 'Duo Core' is a brand of dual core processors associated with Intel Core 2 Duo processors. There is no difference, one is just a brand.

The advantage of dual core and quad core processors over single core processors is that a dual or quad core processor can perform more calculations per second than a single core processor.

Dual core processors are often marked as "duo" in Intel processors. Dual core processors have 2 cores and quad has 4 cores. Quad cores perform better.

modern processors range from dual core to quad core processors.

Technology is rapidly changing to anything is possible. Quad-core processors are next it will be sometime before quad-core processors become the market norm and dual core processors become obsolete.

Core 2 duo is dual core. And before that was core duo which was dual core too...

No. However, processors labeled "AMD Athlon 64 X2" aredual-core processors.

Yes. The Intel D945GNT motherboard supports dual-core Pentium D processors.

Dual core represents two processors in a single system.Speed will be more in dual core systems.

the difference is core 2 duo gives more cooler temperature and supports more features than dual core processors

The Intel Atom is available in both single core and dual-core varieties.The following Atom processors are single-core processors:230D410N270N280N450N470Z500Z510Z515Z520Z530Z540Z550The following Atom processors are dual-core processors:330D510

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.

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 .

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

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.

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

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.

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.

Dual cores have two cores, and Quad cores have four. All the cores are on the same chip they share the same memory and data path to the motherboard. A Dual core processor is basically 2 processors in 1, with some loss. A Quad core is 2 Dual core processors in 1 ,so a Quad core would be twice as fast as a Dual core, while a Dual core is twice as fast as a single core.

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.

dual core processor means two processors which works together to do fast work as compared to single core processor.

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.

dual core in laptops is when u have two processors running instead of just one. with dual core u can run more applications at once than single core laptops dual core in laptops is when u have two processors running instead of just one. with dual core u can run more applications at once than single core laptops

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

"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.
