What are the processors of a computer? Is there a significant difference in functionality?

Computer processor, also known as CPU (English: Central Processing Unit Processor), is one of the main equipment of electronic computers and the core accessories in computers. So what does a computer processor do?

1. Processing instructions: This refers to the order of execution of instructions in the control program. There is a strict order between the instructions in the program, and it must be executed in strict accordance with the order specified in the program in order to ensure the correctness of the computer system.

2. Perform operations: The function of an instruction is often realized by a series of operations performed by the components in the computer. According to the function of the instruction, the CPU should generate the corresponding operation control signal and send it to the corresponding components, and then control these components to act according to the requirements of the instruction.

3. Control time: the implementation of time timing for various operations. In the process of executing an instruction, what to do at what time should be strictly controlled, so that the computer can work in an orderly manner.

4. Data processing: that is, arithmetic and logical operations on data, or other information processing. Its function is mainly to interpret computer instructions and process data in computer software, and to execute instructions.

All operations of the computer are controlled by the CPU, and the performance indicators of the CPU directly determine the performance indicators of the microcomputer system.

**The high or low of the processor directly affects the speed of the computer itself, the higher the speed, the faster it runs.

First, the concept of CPU.

CPU (Central Processing Unit) is also known as ** processor, its main function is to perform operations and logical operations, and the internal structure can be roughly divided into several parts, such as control units, arithmetic logic units and storage units. According to the word length of the information it processes, it can be divided into: eight-bit microprocessor, sixteen-bit microprocessor, thirty-two-bit microprocessor and sixty-four-bit microprocessor and so on.

Second, the main performance indicators of the CPU.

Main frequency: The clock frequency at which the core of the CPU works internally, generally in megahertz (MHz). This is one of the parameters that we usually care about the most, whether we are using it or buying a computer, and it is what we usually refer to when we say "Sho".

For the same type of CPU, the higher the frequency, the faster the CPU speed and the higher the performance of the whole machine. External frequency and multiplier: The external clock frequency of the CPU is the external clock frequency of the CPU.

The external frequency is provided by the computer motherboard, and the relationship between the main frequency of the CPU and the external frequency is: the main frequency of the CPU, the external frequency, and the number of octapers. Internal Cache:

It is made with extremely fast SRAM, which is used to temporarily store the latest part of the instructions and data during CPU operation, and the access speed is the same as the CPU frequency, and the capacity of the internal cache is generally in KB. When it is working at full speed, the larger its capacity, the easier it is for the most frequently used data and results to enter the CPU as soon as possible for computing, and the less data can be exchanged between the CPU and the slower access external cache and memory, and the faster the computing speed can be increased relative to the computer.

In a narrow sense, the processor generally refers to the computing core of the computer, that is, the CPU, also known as the processor.

Nowadays, computer CPUs are divided into two major brands, Intel and AMD, and their functions are similar, and their differences lie in the following aspects:

1. Core architecture. The core architecture of the two CPUs is developed separately, and their core architectures are completely different.

2. Performance. On high, medium and low CPUs of the same level, Intel's CPU performance is better than AMD's.

3. Power consumption and calorific value. AMD's CPU consumes significantly more power than Intel's, and it also generates more heat than Intel's CPU.

4. Process technology. Intel's CPU has a better process than AMD's.

5. Integrated core display. AMD's CPUs outperform Intel's CPUs.

6、**。Intel's CPU** is higher and has low price/performance ratio, whereas AMD's CPU** is lower and cost-effective.

It mainly affects speed.

To put it simply, the application of broadband is mainly related to the processor, such as 2M broadband, and the application of Core is much greater than that of Bensi.

Copying files, such as very large files such as 10g processors, the better the core architecture, the faster the speed, and the frequency is secondary.

For example, when running a game, the better the core architecture of the processor, the better the craftsmanship, the faster the reading speed, and the smoother the game.

It mainly depends on the quality of the core architecture, and the main frequency is secondary.

The processor has made great progress from the early Pentium 1 to 4 generations of 32-bit processors Not to mention the earlier to the current Core i357 32nm process 64-bit processor has made great progress From the Pentium D, I gradually heard that the nanometer once The early dual-core is 65nm The main frequency is very high, but the core architecture and manufacturing process are relatively backward Gradually to 45nm Until the current processor with 32nm process.

The smaller the number of nanometers, the greater the amount of integration, the stronger the performance of the processor, and the simple 65nm main frequency processor is not as good as 60% of the current 32nm processor

The current CPUs are so awesome, and the above frequencies are basically enough. Any amount of more will only lead to a surplus of resources.

So now the key to the computer is the use, according to the use of more memory, 4G is the guaranteed price, 8G is the right way. More awesome graphics card,I think the independent display is either not worthy or with more than 600 basic。 It's best to go directly to more than a thousand, and you don't have to think about upgrading later.

If it's just that ordinary people don't play any games, the motherboard with 880G is absolutely enough. A dual-core high-frequency CPU is sufficient.

Processor.. The better. The faster the computer, the faster.

What is CPU? We can't see the CPU when we play on the computer, but we can see the parameters when we buy the computer, so some friends who don't know about the computer will wonder what the CPU is like and what kind of role does it do? Next, the author will do his best to popularize science to different friends in familiar and easy-to-understand language.

1. What does a CPU look like.

CPU is mainly composed of combinator, controller, register three parts, literally is the operation is to play the role of operation, the controller is responsible for issuing the information required for each instruction of the CPU, the register is to save some temporary files of operations or instructions, so as to ensure higher speed.

Second, what kind of functions does the CPU have?

The CPU has four major functions: processing instructions, performing operations, controlling time, and processing data. So if you don't have a CPU, then the computer is a pile of waste and can't work.

3. What are the parameters of the CPU?

When we look at the CPU, it is mainly from the performance point of view, and the performance parameters include the main frequency, external frequency, bus frequency, frequency doubling coefficient, and cache. The main frequency is the speed of the CPU's operation and processing of data, so the higher the frequency, the faster the CPU responds, which is reflected in the length of time between giving an instruction when we operate the computer and waiting for the computer to respond; The external frequency refers to the running speed of the entire motherboard, which represents the overall performance of the motherboard, and the speed at which the CPU and the motherboard run together. The bus frequency describes the transfer speed between the CPU and the memory, the faster, the faster the computer can exchange data and run multiple programs; The frequency doubling coefficient refers to a proportional coefficient between the CPU main frequency and the external frequency, which can be understood by combining the main frequency and the external frequency; The cache is to store the data that is temporarily needed, so that the CPU does not need to read it from the hard disk and memory, which greatly speeds up the running speed, so the larger the cache, the faster the CPU runs. Therefore, you can choose from this parameter when buying a computer or choosing a CPU for DIY installation.

Fourth, what do we mean by how many cores of the CPU we usually say?

How many cores refers to how many processors the CPU contains, so that multiple processors can share the cache within the CPU, which can greatly speed up, but it is not that the more cores, the better, this is because there are too many cores, it will be troublesome to distribute, but the speed will decrease, just like people, sometimes the same life, too many people and bad allocation will affect the speed.

That's all for what CPU is, I hope everyone can understand what they said above!

is important.

Here are a few options that are important for your computer:

1. Graphics card, before looking at all the configurations, the first thing must be the graphics card. Nowadays, whether it is basic operation or other large-scale programs, the quality of the picture is getting higher and higher, and if you don't have a high-quality graphics card, it is impossible to play those large-scale games, so the graphics card configuration is very important. The capacity of the graphics card is not a problem, about 1G is enough.

But we're going to look at the quality, 128bit DDR5, low-to-mid-range graphics cards. 256bit DDR5, mid-to-high-end graphics card.

2. CPU, with the configuration of the display, then it is necessary to consider the configuration of the processor, the running speed of the CPU also plays an important role, the general large-scale games, designer professions are relatively high on the configuration of the CPU, but ordinary users currently seem to have the CPU in the quad core, more than 3GHz is enough.

3. Memory, if the memory is not enough, when playing games, I like to get stuck and crash. There will even be a reboot, at this time, what we have to do is to replace the memory in time.

The second is the mouse and keyboard, for a computer master, the mouse and keyboard are carried, and the focus is on the feel, so it is up to everyone to feel it themselves.

What you said is more one-sided, first of all, the performance of a computer is determined by the parts with the worst performance, just like the barrel effect, so what you said is not necessarily true, if the processor of a computer is relatively high-end, but the memory is too small, the computer runs very slowly, if the hard disk read and write speed is too slow, it will also slow down the operation of the computer, so the overall performance of the computer is determined by each component, I hope to help the landlord.

The processor is not the most important but it is also the core of a computer, the most important thing should be the graphics card, the graphics card can be said to be a computer point heart, and the processor can be said to be a brain that controls the operation of the entire computer, and the graphics card is to provide power and performance to the body, so relatively speaking, the graphics card is more important than the processor.

The computer is a whole, not only the processor is important, but also the memory, hard disk, motherboard, graphics card, power supply, monitor, and sound card are also important. Because the computer is a collaborative process of various hardware, as long as one hardware is stuck, it is basically very stuck. For example, if the memory is not good, then the read and write speed is so slow, and no matter how good the processor is, it is useless.

The computer processor (centralprocessingunit), abbreviated as CPU, also known as the ** processor, is a functional unit that interprets and executes instructions, is the computing core and control core of a computer, and its function is mainly to interpret computer instructions and process data in computer software. In computer architecture, the CPU is the core hardware unit that controls the allocation of all hardware resources (such as memory, input and output units) of the computer and performs general-purpose operations.

However, with the rapid development of mainstream games, quad-core CPU processing has gradually become a popular choice for consumers, and the importance of CPU has far exceeded that of the graphics card, especially in the process of 3D graphics rendering, although the graphics card plays a key role in the rendering stage, but without the multi-core processing of the CPU, the performance of the graphics card is empty talk.

Many people demand perfection, and if there is a good one, they will replace the good one, and the bad one will be replaced. The processor is definitely important, but if it's not a very complicated, very big game or software, it's generally not too bad, and you don't necessarily need the best. But it is undeniable that the more advanced the better.

The computer processor is equivalent to a person's brain, occupying the most important position, i5 and then add a GTX1060 or more graphics card, usual use, audio-visual entertainment, most of the games are no problem.

It is the most important, because the CPU is the first processor, the final execution unit of information processing and program running, you can't do anything without the CPU, you can not have a discrete graphics card, or you can only insert a memory module, but the CPU is essential.

It's the most important.,But it's important to see which computer you're doing.,Like those games that eat picture quality or do graphic graphic design, the workload of the CPU is not very large.,The graphics card is very important.,But which one is very important in the computer.,Indispensable.。

Equivalent to the heart of the computer ** processor CPU, as the computing and control core of the computer system, is the final execution unit of information processing and program operation. Since its inception, CPUs have made tremendous progress in terms of logical structure, operational efficiency, and functional extension.
