Question

what is dual core processor? how it works?

Answer 1

In April of 2005, Intel announced the Intel® Pentium® processor Extreme Edition, featuring an Intel dual-core processor, which can provide immediate advantages for people looking to buy systems that boost multitasking computing power and improve the throughput of multithreaded applications. An Intel dual-core processor consists of two complete execution cores in one physical processor (right), both running at the same frequency. Both cores share the same packaging and the same interface with the chipset/memory. Overall, an Intel dual-core processor offers a way of delivering more capabilities while balancing power requirements, and is the first step in the multi-core processor future.



An Intel dual-core processor-based PC will enable new computing experiences as it delivers value by providing additional computing resources that expand the PC's capabilities in the form of higher throughput and simultaneous computing. Imagine that a dual-core processor is like a four-lane highway — it can handle up to twice as many cars as its two-lane predecessor without making each car drive twice as fast. Similarly, with an Intel dual-core processor-based PC, people can perform multiple tasks such as downloading music and gaming simultaneously.



And when combined with Hyper-Threading Technology† (HT Technology) the Intel dual-core processor is the next step in the evolution of high-performance computing. Intel dual-core products supporting Hyper-Threading Technology can process four software threads simultaneously by more efficiently using resources that otherwise may sit idle.



By introducing its first dual-core processor for desktop PCs, Intel continues its commitment and investment in PC innovation as enthusiasts are running ever-more demanding applications. A new Intel dual-core processor-based PC gives people the flexibility and performance to handle robust content creation or intense gaming, plus simultaneously managing background tasks such as virus scanning and downloading. Cutting-edge gamers can play the latest titles and experience ultra-realistic effects and gameplay. Entertainment enthusiasts will be able to create and improve digital content while encoding other content in the background.



The new Intel Pentium processor Extreme Edition ushers in a new era in processor architecture design in which multi-core processors become the standard for delivering greater performance, improved performance per watt, and new capabilities across Intel's desktop, mobile, and server platforms. This new Intel dual-core product also represents a vital first step on the road to realizing Platform 2015, Intel's vision for the future of computing and the evolving processor and platform architectures that support it.

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 a dual core processor each core handles incoming data strings simultaneously to improve efficiency. Just as two heads are better than one, so are two hands. Now when one is executing the other can be accessing the system bus or executing its own code. Adding to this favorable scenario, both AMD and Intel's dual-core flagships are 64-bit.



To utilize a dual core processor, the operating system must be able to recognize multi-threading and the software must have simultaneous multi-threading technology (SMT) written into its code. SMT enables parallel multi-threading wherein the cores are served multi-threaded instructions in parallel. Without SMT the software will only recognize one core. Adobe Photoshop is an example of SMT-aware software. SMT is also used with multi-processor systems common to servers.



A dual core processor is different from a multi-processor system. In the latter there are two separate CPUs with their own resources. In the former, resources are shared and the cores reside on the same chip. A multi-processor system is faster than a system with a dual core processor, while a dual core system is faster than a single-core system, all else being equal.



An attractive value of dual core processors is that they do not require a new motherboard, but can be used in existing boards that feature the correct socket. For the average user the difference in performance will be most noticeable in multi-tasking until more software is SMT aware. Servers running multiple dual core processors will see an appreciable increase in performance.

Answer 4

In simple, processors which came before dual had only one way for input and output. u cannot add another input during a process. so it wil take time whatever the processor speed maybe. But dual has two ways . one for input and the other for output. so even a 1ghz dual core would perform equivalent to a 2ghz single core processor. I hope it doesnt get simpler

Answer 5

It is like having two processors side by side sharing the work load.



Each one processing data at the same time.Hence the net speed of processing is improved. As clock speeds and the related heat issues have increased AMD and Intel are looking for ways to speed up the computer without increasing the generation of heat.



The air cooling has neared it's practical limit and liquid cooling is expensive so the dual core provides higher processing speed without a big increase in heat generation.

Answer 7

This type of processor will permits to run two programs or more with the same quality in the same time , so the programs will run faster, it is like to have two different processors working side to side in the same time.these processor wll be a big happen in the manfacture of hardwares.

Answer 8

Basically its two processor packed to one. In your operating system, say Windows, if go to hardware device manager, you will find two processors.



Before you can only archieve this on a dual socket motherboard.

Answer 9

HEI USUALLY A PROCESSOR WILL HAVE ONLY ONE SIDE OF CAPACITORS IN IT BUT A DUAL CORE PROCESSOR WILL HAVE BOTH THE SIDES THE CAPACITORS IN IT. SO IT WILL BE FASTER THAN OTHERS.
