What is a GPU? Whether you watch your favorite movies through the computer, play multiplayer online games massively or simply scan or upload photos via the web; The quality and intensity of the graphics you experience is just as good as the video card you installed.

A graphics card GPU computer definition refers to any computer device or program that enables the computer to view and manipulate images. It is a computer component designed to convert the logical representation of visual information into a signal that can be used as input to a display medium. 

Simply put, a graphics card is an integrated or expansion card whose main function is to create output images for a display medium. Display means include monitors, LCD (Liquid Crystalline Display) TVs, High Definition (HD) TVs, and projectors. define GPU

Most often these graphics cards have added functions that include the following GPU meaning: accelerated processing of 3D scenes and two-dimensional graphics; Video shooting; As a TV tuner adapter; Decoding of MPEG-2 / MPEG-4; Ability to connect multiple monitors; And as a TV output. 

Modern high-performance cards are used for computer game purposes, some of which are graphically demanding. graphics card meaning

You can use a replaceable graphics card with the terms video card, video adapter, graphics accelerator, and display adapter.

Components of a Graphics Card

In addition to the motherboard interface and printed circuit board as a base, a modern graphics card contains the following components:

1. What Is a GPU? Graphics Processing Unit

A graphics processing unit (GPU definition) is a dedicated processor that is specially adapted for accelerating graphics. It is designed to perform the basic floating-point calculations for processing 3D graphics and drawing two-dimensional images. 

One of the main features of the GPU is its central clock frequency which translates a three-dimensional image characterized by vertices and lines into a two-dimensional image created by pixels. Dedicated graphics card meaning.

2. Video BIOS

The video BIOS, also known as the firmware, contains the basic program that controls the operations of the graphics card and instructs the computer and software to communicate with the card. 

The video BIOS may contain relevant information such as random access memory (RAM), memory scheduling, operating speeds, and graphics processor voltages.

3. Video Memory

Video memory is used to store a lot of data as well as a screenshot, such as the Z repository. The Z repository manages the depth coordinates in 3D graphics, textures, vertex repositories, and complex shading programs.


The RAMDAC, or an analog-digital converter of random access memory, is responsible for converting digital signals to analog signals that will be used by the computer monitor that uses analog inputs such as Cathode Ray Tube (CRT) monitors. RAMDAC functions as a RAM chip that regulates video card performance.

5. Outputs

Video cards and display modules must be connected by some means. The most common connection systems between the two are: the analog-based Video Graphics Array (VGA) array; DVI (Digital Digital) based digital visual interface such as flatbed LCD and video projectors; Video In Video Out (VIVO) for connecting TVs, DVD players, video recorders and video game consoles; And a High Definition (HDMI) multimedia interface commonly used for game consoles.

6. Power Demand

Today, a high-performance graphics card tends to consume a large amount of electrical energy. As the processing power of the video card increases, so does its power demand. 

Despite efforts to optimize the latest processors and power supply, the power requirements of GPUs still continue to rise thus making the video card the largest power consumer in the computer.

7. Cooling Devices

Because the video card uses a lot of energy, some of it is expected to be converted to heat. If the heat generated does not dissipate into the atmosphere then the video card will rise excessively and in the process be damaged.

To address this problem, developers have incorporated refrigeration appliances that allow heat transfer to another location. There are three types of refrigerators used in the card. These are using a passive cooling device of cooling, a computer fan, and the installation of a block of water.

Card Types

What is a GPU? There are currently two types of cards available in the market. These are combined type cards and expansion cards.

Integrated graphics meaning or Integrated video cards are components that are already built into the system motherboard. It uses the system processor (CPU) and memory to create the actual graphics. Dedicated GPU meaning.

While integrated cards can process complex graphics such as 3D images, they must share the CPU and memory with other programs. 

If in some cases both the CPU and the memory are overloaded, the video card is affected very quickly. Thus, this type of card is useful for applications such as word processing and web browsing, but not much in games or other graphics-intensive programs. Definition of graphics card.

The expansion card, on the other hand, works autonomously and does not depend much on the computer processor and memory. Because of this, an expansion graphics card is considered to be the most powerful graphics hardware capable of delivering quality 3D graphics. The expansion type card is further divided into two: a discrete video card and a dual video card.

Because 3D cards for modeling art and animation are different from those intended for games, a specific type of expansion card is used. 

Although they have similar hardware, their drivers and firmware are tailored to specific tasks. What is a GPU? A discrete graphics card is designed to achieve high-quality 3D graphics and is therefore suitable for gaming, while the dual graphics card is used to display huge files at the highest speed typically used for high-precision processing.
