Modern devices use a graphics processor, which is also referred to as a GPU. What is it and what is its working principle? GPU (Graphics Processing Unit) - a processor whose main task is the processing of graphics and floating-point calculations. GPU facilitates the work of the main processor, when it comes to heavy games and applications with 3D-graphics.
What is it?
The GPU creates graphics, textures, colors. A processor that has multiple cores can run at high speeds. The graphic has many cores that operate primarily at low speeds. They do pixel and vertex calculations. Processing of the latter mainly occurs in the coordinate system. The graphic processor processes various tasks, creating a three-dimensional space on the screen, that is, objects in it move.
Principle of operation
What does the GPU do? He is engaged in processing graphics in 2D and 3D. Thanks to the GPU, your computer can perform important tasks faster and easier. The peculiarity of the graphic processor is that it increases the speed of calculating graphic information at the maximum level. Its architecture is designed so that it can process visual information more efficiently than the central computer CPU.
He is responsible for the location of three-dimensional models in the frame. In addition, each type of GPU filters the triangles included in it. It determines which ones are in sight, deletes those that are hidden behind other objects. Draws light sources, determines how these sources affect color. The graphics processor (what it is - described in the article) creates an image, displays it to the user on the screen.
Efficiency
What determines the efficient operation of the GPU? Temperature. One of the problems with PCs and laptops is overheating. That is what becomes the main reason why the device and its elements quickly fail. Problems with the GPU begin when the temperature of the processor exceeds 65 ° C. In this case, users notice that the processor starts to run weaker, skips clock cycles in order to independently lower the increased temperature.
The temperature regime of 65-80 ° C is critical. In this case, the system reboots (emergency), the computer shuts down on its own. It is important for the user to ensure that the temperature of the GPU does not exceed 50 ° C. Normal is considered t 30-35 ° C in idle time, 40-45 ° C at many hours of load. The lower the temperature, the higher the performance of the computer. For the motherboard, video card, case and hard drives - its own temperature conditions.
But many users are also worried about the question of how to reduce the temperature of the processor in order to increase its efficiency. First you need to find out the cause of overheating. This may be a clogging of the cooling system, dried thermal grease, malware, overclocking of the processor, raw BIOS firmware. The simplest thing a user can do is replace the thermal grease that is on the processor itself. In addition, you need to clean the cooling system. Experts also advise installing a powerful cooler, improving air circulation in the system unit, and increasing the rotation speed on the cooler's graphics adapter. For all computers and GPUs, the same temperature reduction scheme. It is important to monitor the device and clean it on time.
Specificity
The graphics processor is located on the video card, its main task is the processing of 2D and 3D graphics. If a GPU is installed on the computer, then the device’s processor does not do unnecessary work, therefore it functions faster. The main feature of the graphic is that its main goal is to increase the speed of calculating objects and textures, that is, graphic information. The processor architecture allows them to work much more efficiently, process visual information. An ordinary processor cannot do this.
Views
What is a graphics processor? This is a component that is part of the video card. There are several types of chips: built-in and discrete. Experts say that the second copes better with its task. It is installed on separate modules, as it is distinguished by its power, but it needs excellent cooling. Built-in graphics processor is in almost all computers. It is installed in the CPU to make power consumption several times lower. It cannot be compared with discrete ones in power, but it also has good characteristics and demonstrates good results.
Computer graphics
What's this? This is the name of the area of activity in which computer technology is used to create images and process visual information. Modern computer graphics, including scientific, allows you to graphically process the results, build diagrams, graphs, drawings, and also make various kinds of virtual experiments.
Using constructive graphics, technical products are created. There are other types of computer graphics:
- animated;
- multimedia;
- art;
- advertising;
- illustrative.
From a technical point of view, computer graphics are two-dimensional and three-dimensional images.
CPU and GPU: the difference
What is the difference between these two designations? Many users are aware that the graphics processor (which is described above) and the video card perform different tasks. In addition, they differ in their internal structure. Both CPU and GPU are processors that have many similar features, but they are made for different purposes.
The CPU executes a certain chain of instructions in a short period of time. It is made so that it forms several chains at the same time, splits the flow of instructions into many, executes them, then merges them again into a single whole in a specific order. The instruction in the stream depends on those that follow it, so the CPU contains a small number of execution units, here the main priority is given to the speed of execution, reducing downtime. All this is achieved using the pipeline and cache memory.
The GPU has another important function - rendering visual effects and 3D graphics. It works easier: it receives polygons at the input, performs the necessary logical and mathematical operations, and outputs pixel coordinates at the output. The work of the GPU is the operation of a large stream of different tasks. Its peculiarity is that it is endowed with a large amount of memory, but it works slowly compared to the CPU. In addition, modern GPUs have over 2,000 execution units. They differ among themselves by methods of access to memory. For example, a graphic does not need large cached memory. The GPU has more bandwidth. To explain in simple words, the CPU makes decisions in accordance with the tasks of the program, and the GPU performs many identical calculations.
