What is a Graphics Card

Graphics card

A Graphic Card is the computer hardware that creates the image you see on your monitor; the graphics card is responsible for rendering an image on your monitor, and it does this by converting the data into a signal your monitor can understand. A smoother and better image can be produced. This is of course very important for gamer’s and video editors.


Integrated: Graphics integrated on the motherboard where no additional card is used. They are built into most “standard” laptops and desktops. They are a profitable model, but because they are “frozen” they cannot be easily upgraded.

Discrete – An additional graphics card that is installed as an additional component on the motherboard. This type is ideal for those who want to modify their system by updating the graphics card at a later date. Most people who use a modern computer for standard tasks such as surfing the Internet, creating documents, or watching movies will be fine with built-in graphics.For users interested in games or video editing, a separate graphics card is usually required to accelerate image processing. Without this, the user can find that his game is being delayed or stirred up at crucial points.


GPU stands for Graphics Processing Unit, is the “brain” of the graphics card and generates the images that you see on the screen.The performance of a GPU depends on the model you choose. In fact, the GPU is like a translator. Obtain data from the CPU (Central Processing Unit) and convert it into an image. High definition games require more complex and faster GPUs to adapt to the flow of data.

Expansion Slot 

 You can expand your computer by adding additional cards inside.Over the years, the graphics expansion slot has evolved from PCI (Peripheral Component Interconnect)AGP (Accelerated Graphics Port) to PCIe (Gen1 / 2/3) (PCIexpress) with the best bandwidth. Some motherboards have expansion slots that allow users to add more than one graphics card. This is known as SLI (NVIDIA) or CrossfireX (AMD) and allows users to improve their system’s performance.

The intention is to link two of the same graphics cards together.
CrossfireX, also known as Crossfire, was developed by AMD. NVIDIA developed SLI (Scalable Link Interface) to connect multiple cards in a system. SLI works by increasing the computing power available for graphics use. To be able to use these technologies, you need an SLI- or Crossfire-capable motherboard.


Modern games offer incredible realism and stunning graphics. To get a near-perfect picture, your PC must be able to deliver these details at an acceptable frame rate (this is the number of times a game can be updated or refreshed) image you see. This value is displayed in frames per second (or FPS).

If your graphics card’s frame rate is too low, the smooth motion you would expect your game to be becomes a slow and choppy drag best. than your PC since 1998. For a user to have the best experience, their graphics card must be up to the task.


Graphics cards are not only useful for gamer’s. Discrete graphics cards can also significantly improve the user experience of photo and video editing by increasing the rendering speed of images.


There are two major manufacturers of discrete graphics cards: AMD and NVIDIA. Some users have allegiance to a particular brand, but everyone will do the same job. AMD also produces some integrated graphics options, as does current market leader Intel.


Today’s graphics cards also contain RAM. This is dedicated graphics memory that is different from your PC’s RAM.
Memory is important in a graphics card because it allows users to play games at higher resolutions. Great for those who use games that contain very large texture packs.
At least 1GB of memory is recommended for gamer’s, but this has to be weighed against other aspects of the card and the resolution you are playing at.


Graphics cards can support multiple monitors. However, the number is determined by the GPU and the number of outputs available. Check the specifications of each graphics card to find out how many monitors it can support.


graphics cards can be connected to a monitor using various output options. You need to select a graphics card that will match a port on your monitor. Many graphics cards have at least two or three ports, some of which can support more.

VGA (Video Graphics Matrix) – 15-pin analog connector (also known as DSub). This is the oldest video connection and therefore currently the least efficient. The VGA connectors work well enough, but other connectors provide better video quality.

DVI (Digital Visual Interface): DVII (carries analog and digital signals) and DVID (carries only digital signals) DVI is found in most flat panel displays, which makes it a useful connection between the card and the screen. 

HDMI: This is one of the most commonly used connectors because of its speed and versatility. HDMI transmits video and audio signals.

DisplayPort: This type of connection is becoming increasingly popular and can be seen in the new generation of monitors. It carries video and audio, as well as other forms of data.


As with many components, the aesthetics (style and design) of a graphics card can be important to users, especially gamers. And if you have limited space on your PC, scaled-down options are available in addition to the usual full-size components.

ATX / Full Height: This is essentially the standard full size desktop PC card / media with no space issues.

Low Profile: Half-height graphics cards that are thinner than the ATX style and accept the smaller media often used in HTPC.
