What Is the Core of A Processor?

A processor is an electronic device that includes several blocks between them are very interesting which are called nuclei which are responsible for implementing the instructions and can be seen as a miniature mics.

Multicore processors have gained popularity over the years so that now almost impossible to find one that not more than one of them inside.

This has been made possible by improvements in manufacturing technology that has allowed greatly reduce the size of the micros giving more free space engineers can therefore double or even triple their internal blocks. In this way we can run a single task to work with several at once.

The idea is not new. Before they could integrate two or more cores inside the chip multiprocessor computers existed. In these there were more than a micro on the same motherboard. As you can imagine they were expensive and needed special plates to make them work. The idea is essentially the same but much more efficient to be all inclusive within the same chip.

A processor with two cores is twice as fast as one with a nucleus?

Not all applications are able to use more than one core simultaneously. To better understand this imagine a program that will add a very large series of numbers. If you use a single core, it must perform all operations one to one to continue.

If the initial series of numbers is divided into multiple sets when doing this you can accelerate using more than one core. Now you can add the total at the end of each operation.

Note that sucrase party to this advantage alone and only if the program with which the intervention of programmers is necessary adapted.

In other situations have two or more nuclei leads to very large performance gains. Especially to avoid blockages as occur almost so continues with programs that are in memory such as antivirus. A utility like this is able to consume 100% of a core, stopping the execution of other applications until they finish their work. In such cases provide more cores improves the response of the whole system radically.

Dual-core processors are therefore more agile in responding to your commands. The operating system is more filed. But you must not think that generally finish their work in half the time.

Is it for something more than two cores?

You must be thinking, if two cores we are able to remove some blockages, what we can not do with three or more? In principle, if you have more cores, the processor can work with more applications and perform more tasks simultaneously.

Manufacturers and designers that gain micros have clear benefits and the trend goes in the future have more cores in each processor. Unfortunately, most utilities and applications can not benefit either directly or indirectly since their operations can not be performed in parallel.

However if it is true that there are tasks that benefit more clearly the increase of cores:

Photo retouching. Especially in the application of filters. A multi-core processor can simultaneously calculate different regions of the same image. In these cases the speed increases linearly with the number of these elements.

Video works. Is similar to what happens in the previous case, the utility can work with more than one frame at a time accelerating the process.

Strategy games. There are many games in which the next move is based on calculations on future positions, the clearest case is chess. If these positions can be evaluated independently, a processor with a larger number of cores will always be an advantage. Unfortunately not accelerate in the same way other games.

Rendering. Creating 3D images also takes advantage of this increase. The reason is similar to the photo retouching since programs can calculate different regions independently. Do not confuse these images with those used in PC games that are created by the graphics card and that in principle the type of processor gives almost the same.

What would be the ideal number of cores?

For applications other than the above four cores is more than enough as the programs and the operating system itself, they are unable to get juice of a micro with a greater number of them.
