What is CPU and what are the values? What is a graphics card and what are the values? Ask for explan

CPU,** processor, mainly Intel and AMD, AMD has a great disadvantage in performance than Intel in the same positioning of products in the same year, but it is more cost-effective, notebook AMD's CPU because of poor performance, although it is cheaper, but it is not recommended to buy, the architecture of the two is different, so there is no way to compare simply with the number of cores or the main frequency, the following is the CPU ladder diagram, representing CPU performance.

Graphics card manufacturers have nvidia and amd,You can look at the core codename,Main frequency,Number of stream processors,Video memory bit width, etc.,Now the size of the graphics card's video memory is no longer a bottleneck,Therefore, it is not used as a criterion for judging the performance of the graphics card。。。 Ordinary look at the performance of the graphics card,Look at the model of the graphics card,The first is the product age,The new generation of products will generally have higher performance than the previous generation of products with the same positioning,The second place is the positioning of the product,The third place is the subdivision of the product under this positioning,That is to say,The graphics card of the same manufacturer in the same era,The performance size is better than the second and third two places,The bigger the performance, the better,The fourth nvidia does not,AMD is 0。。。 Products of different ages and products of different manufacturers are not absolutely comparable.

If the desktop graphics card is not included, you will be given a ladder diagram of the notebook graphics card, and the model encoding method is the same as that of the desktop, and the desktop machine does not have the suffix m

CPU is the ** processor, there are too many values, I used to look at the main screen, now just look at the price, the price can basically represent everything. There is also AMD at the same price, and the performance is stronger than Intel's.

The memory mainly depends on the algebra and the screen, and there is also a memory timing, which is similar to the memory timing of the generation.

Just the model. <>

1.There is a specific meaning, which can be understood as the grade of the CPU, the larger the number, the better (it is meaningful to compare between processors with the same suffix M or U, such as i5 3317U, i73667U The code name of the frequency, the larger the number, the higher the frequency (main frequency turbo frequency).

2.The numerical code name of the low-power processor, 0 represents the ordinary version of the CPUU: the alphabetical code of the low-power processor, TDP17W, M represents the ordinary version of the processor, dual-core TDP35W, quad-core TDP45W Core series CPU model The meaning of the first letter of the CPU model is currently in the Core 2 dual-core, and the CPU type is also divided into E series, Q series, T series, and X series.

The system is the dual-core CPU of the ordinary desktop machine, the power is about 65W, the Q series is the quad-core CPU, the power will be in the 100W-150WT series is an ordinary note CPU, the power is 5W or 31WX series is the Core 2 dual-core Extreme Edition, the power of the X series CPU of the notebook is 45W, and the CPU power of the X series of the desktop is about 100W.

The series is Centrino's low-voltage CPU, the power 25WL series is the low-voltage CPU of Centrino 4, the power 17W series is Centrino's ultra-low voltage CPU, the power system is a small package series, the power of SL is 12W, and the notebook of SP is not currently on the market, and the power is unknown.

The biggest difference between them is that they don't work the same. The CPU is an indispensable part of the computer, and the graphics card is not required, and the computer can run normally.

CPU Features:

**The CPU (Central Processing Unit) is a very large-scale integrated circuit, which is the computing core and control unit of a computer. Its function is mainly to interpret computer instructions as well as process data in computer software.

**The processor mainly consists of combinators (ALUs, arithmetic logic units) and caches, as well as buses that enable the data, control and state between them. Together with internal memory and input and output (IO) devices, it is known as the three core components of electronic computers.

Graphics card features: <>

Video card, graphics card, also known as graphics card, is one of the most basic configuration and most important accessories of a computer. As an important part of the computer host, the graphics card is a device for the computer to convert digital-to-analog signals, and undertakes the task of outputting and displaying graphics.

The graphics card is connected to the motherboard of the computer, which converts the digital signal of the computer into an analog signal for the display of the display, and the graphics card still has image processing capabilities, which can assist the CPU to work and improve the overall running speed.

For people who are engaged in professional graphic design, graphics cards are very important. The leading manufacturers of graphics chips for civil and military graphics cards include AMD (Supermicro Semiconductor) and NVIDIA (Nvidia). Today's TOP500 computers all contain graphics card computing cores.

In scientific computing, graphics cards are referred to as display accelerator cards.

1. Capacitor: Capacitor is a very important component of the graphics card, because the quality of the display mainly depends on the quality of the capacitor, and the quality of the capacitor directly affects the quality of the graphics card circuit.

2. Video memory: Video memory is responsible for storing all kinds of data that the display chip needs to process, and the size of its capacity and performance directly affect the display effect of the computer. The new graphics cards all use DDR3 DDR5 video memory, and the mainstream video memory capacity is generally 1GB and 2GB.

3. GPU and fan: GPU is the graphics card chip, which is responsible for most of the computing work of the graphics card, which is quite dry about the role of the CPU in the computer. The role of the GPU fan is to dissipate heat from the GPU.
