The Number Of Cores In A Laptop What Affects

What is responsible for the number of cores in a laptop

When buying a processor, many people try to choose something cooler, with multiple cores and a high clock speed. But at the same time, few people know what the number of processor cores actually affects. Why, for example, a regular and unpretentious dual-core can be faster than a quad-core or the same “percent” with 4 cores will be faster “protsa” with 8 cores. This is a pretty interesting topic that is definitely worth exploring in more detail.

How to find out how many cores

If someone does not know how to determine the number of processor cores, then this can be done easily and simply even without downloading and installing SEPARATE Special Programs. You just need to go to “device Manager” and click on the little arrow next to the item “Processors”.

Intel

So, today at Intel, 5 types of processors are successful: Celeron, Pentium, Core i3, i5, and i7. Each of THESE “stones” has a different number of cores and is designed for different tasks. For example, Celeron has only 2 cores and is used mainly on office and home computers. Pentium, or, as it is also called, “stump”, also used at home, but already has much better performance, primarily due to Hyper-Threading technology, which “adds” physical two cores have two more virtual cores, which are called threads. So dual-core “percent” works like the most budgetary quad-core, although this is not entirely correct, but the main point is precisely this.

As for the Core line, the situation is roughly the same. The younger model with number 3 has 2 cores and 2 threads. The older line. Core i5. already has a full-fledged 4 or 6 cores, but only for the Hyper-Threading function and has no additional threads, except for 4-6 standard ones. And the last thing. core i7. these are top-end processors, which, as a rule, have from 4 to 6 cores and twice as many threads, i.e., for example, 4 cores and 8 threads or 6 cores and 12 threads.

Now let’s talk about AMD. List “pebbles” from this company is huge, it makes sense to list all the comments, since most of the models are already simply outdated. Perhaps it is worth noting a new generation, which in a sense “copies” “Intel”. Ryzen. This line also contains models with numbers 3, 5 and 7. The main difference from “blue” in Ryzen is that the youngest model already immediately provides a full 4 cores, and in the older one there are not 6, but eight. In addition, the number of threads varies. Ryzen 3. 4 threads, Ryzen 5. 8-12 (depending on the number of cores. 4 or 6) and Ryzen 7. 16 threads.

Another line worth mentioning “red”. FX, which appeared in 2012, and, in fact, this platform is already considered outdated, but thanks to the fact that now more and more programs and games begin to support multithreading, the Vishera line has regained its popularity, which, along with low prices, is only growing.

Well, as for the disputes over the frequency of the processor and the number of cores, then, in fact, it is more correct to look towards the second, since everyone has long been determined with the clock frequencies, and even the top models from “Intel” operate at nominal 2. 7, 2. 8 3 GHz. In addition, the frequency can always be raised using overclocking, but in the case of a dual-core processor, this will not give much effect.

Before starting to understand what the number of processor cores affects, I would like to make a small digression. A few years ago, the developers of the Central Bank were confident that production technologies, which are developing so rapidly, will allow the production of “stones” with clock speeds up to 10 GHz, which will allow users to forget about problems with poor performance. However, no success was achieved.

No matter how the process technology develops, that “Intel”, what “AMD” ran into purely physical limitations, which simply did not allow the release “prots” with a clock frequency of up to 10 GHz. Then it was decided to focus not on frequencies, but on the number of cores. Thus, a new race has begun to produce more powerful and efficient processor “crystals”, which continues to this day, but not actively for centuries, as it was at first.

Intel and AMD processors

Today “Intel” and “AMD” are direct competitors in the processor market. If you look at revenue and sales, then a clear advantage will be on the side “blue”, although lately “red” try NOT to lag behind. Both companies have a good range of ready-made solutions for all occasions. from a simple processor with 1-2 cores to real monsters in which the number of cores exceeds 8 Usually similar “stones” used on Special Workers “computers”, Which have a narrow focus.

6 and 8 cores

Well, the last segment of multi-cores is processors with six and eight cores. Their main purpose, in principle, is exactly the same as in the Central Bank above, only now they are needed where the usual “fours ”fail. In addition, based on “stones” with 6 and 8 cores, they are building full-fledged profile computers, which will “sharpened” for certain activities, for example, video editing, 3D modeling programs, rendering of ready-made heavy scenes with a large number of polygons and objects, etc. D.

In addition, such multi-cores show themselves very well in working with archivers or in applications where good computing power is needed. In games that are optimized for multithreading, equal to such processors comments.

The better 4 cores

How can 4 cores be better than two? Better performance. Quad-core “stones” designed for more serious work, where simple “hemp” or “selerones” they simply cannot cope. Any 3D graphics program like 3Ds Max or Cinema4D is a great example.

During the rendering process, these programs use the maximum computer resources, including RAM and processor. Dual-core CPUs will lag very much in render processing time, and the more complex the scene, the longer it will take. But processors with four cores will cope with this task much faster, since additional threads will also come to their aid.

Of course, you can take some budget “Protsik” from the Core i3 family, for example, model 6100, but 2 cores and 2 additional threads will still be inferior to a full-fledged quad core.

How to see how many cores are in a processor. 7 ways

It is often necessary to find out how many cores are in the processor installed on the user’s computer. This information is useful when upgrading your PC, or to get information about potential CPU performance.

The central processing unit (CPU) is the most important part of a computer that processes machine data: instructions and program code that controls peripheral devices. Here are the capabilities of the CPU (Central Processing Unit) depends on the operation of the entire computer.

The main characteristics of the processor are:

  • Performance (Compute Power). Average number of operations performed per second.
  • Clock frequency is the number of clock cycles per second, measured in GHz (gigahertz).
  • Bit depth. determination of the number of bits of information processed simultaneously.

To improve the performance of the central processor, the developers constantly increased the maximum clock frequency. Over time, the growth of this indicator slowed down, including due to the design features of the Central Bank.

A movement began towards an increase in the number of cores working in parallel in several threads. A larger number of cores per processor allows for multi-threaded operation, increasing the overall processing power.

Taking this information into account, questions arise about how many cores are in an Intel processor, how many cores are in AMD processors. American companies Intel and AMD. The largest manufacturers of central processing units used for industrial purposes and on computers of ordinary users.

Diagnostic tools and information often show, in addition to the number of cores, the number of logical processors (threads), which confuses ordinary users. On some modern processors, two threads are added to one physical core.

There are several ways to get information about the number of CPU cores. In this article, you will find instructions on how to find out how many cores in a processor using the tools of the Windows operating system, or using third-party software.

Many users, for one reason or another, need information on the number of CPU cores. Here are the characteristics of the central bank depends on the overall performance of the computer. You can get information about the processor cores of your computer using the built-in tools of the Windows operating system, or using third-party software: specialized programs.

Multicore and multithreading

When we studied the question of how to find out the number of cores, we drew attention to the peculiarity of Intel processors. a different number of cores is displayed in standard Windows tools. This is due to the operation of Hyper-Threading Technology, which enables multithreading.

So that you are no longer confused in concepts, let’s figure it out once and for all:

  • Multi-core. The chip is equipped with multiple physical architectural cores. You can see them, touch them with your hands.
  • Multithreading. several simultaneously processed information streams.
    The kernel may be physically equal, but software technologies based on it create two threads of task execution; two cores. four threads, etc.

Impact of the number of cores on performance

The increase in performance on a multi-core processor is achieved by splitting the execution of tasks. Any modern system divides the process into several threads even on a single-core processor. this is how the same multitasking is achieved in which you can, for example, listen to music, type a document and work with the browser. The following applications are very fond of and constantly use multithreading:

  • Archivers;
  • Media player;
  • Video encoders;
  • Defragmenters;
  • Antiviruses;
  • Graphic editor.
number, cores, laptop, affects

The principle of separation of streams is important. If the computer runs on a single-core processor without Hyper-Threading Technology, the operating system instantly switches between threads, so that for the user the processes are visually executed simultaneously. All actions are performed within milliseconds, so you DO NOT see serious latency if you are not heavily loading the CPU.

If the processor is multicore (or supports multithreading), then ideally it will not be switched. The system sends a separate thread to each core. The result is increased productivity because there is no need to switch to another task.

But there is another important factor. does the program itself support multitasking? The system can split processes into different threads. However, if you run a very demanding game, but it is NOT optimized for working with four cores, there will be no performance gain in comparison with a dual-core processor.

Developers of games and programs are aware of this feature, so they are constantly optimizing their code to perform tasks on multi-core processors. But this optimization does not always keep pace with the increase in the number of cores, so it is not worth spending huge money on the newest powerful processors with the maximum possible number of supported threads. the potential of the chip will not be revealed in 9 programs out of 10.

What affects the number of processor cores

All right, users would just be mistaken and did NOT lose anything. The problem is that misunderstanding the essence of multicore leads to financial losses. Trying to increase performance, a person spends money on a processor with a large number of cores, but does not notice the difference.

So how many cores to choose?

Before buying a processor with 16 cores, consider whether you need so many threads to perform the tasks that you will put in front of your computer.

  • If a computer is purchased for working with documents, surfing the Internet, listening to music, watching movies, then two cores will be enough. If we take a processor with two cores from the upper price segment with good frequency and multithreading support, it will not be a problem when working with graphic editors.
  • If you buy a machine with a strong gaming performance in mind, then immediately put the filter on 4 cores at least. 8 cores with multithreading support. the top with a margin of several years. 16 cores is promising, but there is a high probability that until you unleash the potential of such a chip, it will become obsolete.

The advantages of multicore can be seen only in very serious computational work in several threads. If, conditionally, a game or program is optimized for only four threads, then even your eight cores will be meaningless power, which will NOT affect performance in any way.

It’s like transporting a chair on a huge truck. the task is not completed faster. But if you use the available opportunities correctly (for example, load the body with completely different furniture), then labor productivity will increase. Keep this in mind and DO NOT get fooled by marketing gimmicks that add the word “gaming” to processors that will NOT reach their full potential even on the latest games.
