A graphics card is a piece of computer hardware that generates the image you see on your screen.
The Graphics Card is in charge of translating data into a signal that your monitor can understand in order to render an image to your device.

The stronger and cleaner a picture can be made, the better your graphics card is. For gamers and video editors, this is obviously important.

Graphics card


Integrated graphics are graphics that are integrated into the motherboard rather than using an add-in card. These are used in most ‘standard’ notebooks and computers; they are a cost-effective type that cannot be updated quickly.

Discrete – An add-in graphics card that is mounted as an additional component on the motherboard. Ideal for those who want to upgrade their graphics cards to customise their setup.

The integrated graphics would suffice for most people who use a modern computer for routine activities such as browsing the internet, making documents, or watching movies.

A discrete graphics card is normally needed for users venturing into gaming or video editing to speed up the image processing time. Without this, the user can experience lagging or jittering at critical moments in the game.

Graphics Processing Unit (GPU) is the abbreviation for Graphics Processing Unit. It’s the graphics card’s brain, and it’s what generates the visuals you see on the screen. The performance of such GPUs can vary depending on the model you use.

The GPU acts as a translator, taking data from the CPU and converting it to imagery. To handle the flood of data, more complicated graphics, such as those used in high-definition games, necessitate more complex and faster GPUs.


Internally, you can extend your PC by inserting more cards. Graphics expansion slots have evolved greatly over time, from PCI (Peripheral Component Interconnect) and AGP (Accelerated Graphics Port) to the more recent PCI-E (Gen1/2/3) (PCI-Express) slots, which provide the highest bandwidth.

Few motherboards have expansion slots that enable users to connect several graphics cards to their system. This is known as SLI (NVIDIA) or CrossfireX (AMD) which allows users to get more results from their system. To use these technologies, users would need a motherboard that supports SLI or Crossfire. The aim is to connect two graphics cards that are the same.
SLI, or Scalable Link Interface, is a technology that was developed by Intel.

NVIDIA created SLI, or Scalable Connection Interface, to connect multiple graphics cards in a single device. SLI works by increasing the amount of computing power required for graphics.
AMD’s CrossfireX, also known as Crossfire, is a graphics card.

FPS (first-person shooter)

Modern games offer 3D combat and Photoshop realism, but the user’s graphics card must be up to par to have the best experience.
Your PC must be able to deliver these details at an appropriate frame rate (the amount of times a game will update/refresh the image you see) in order to get the crisp image. This statistic is represented in frames per second (FPS). If your graphics card’s frame rate is too poor, the smooth motion you see would be lost.
The smooth, jerky movement you’d expect from a £50 game devolves into a sluggish, jerky crawl that’s no better than your PC from 1998.


Discrete graphics cards aren’t just for gamers; they can also support users of picture and video editing applications by increasing the speed at which images are made, as well as helping users with high-definition displays.
MANUFACTURERS There are two major manufacturers of standalone graphics cards: AMD and Nvidia. While some users prefer one brand over the other, both will perform the same tasks. AMD, like the current industry leader, Intel, offers several integrated graphics options.


The RAM memory on today’s graphics cards is dedicated graphics memory, which is distinct from the RAM on your PC. Most modern graphics cards would have memory capacities ranging from 512MB to 8GB, with DDR3 and GDDR5 SDRAM being the most common formats.

Memory on a graphics card is vital since it enables users to play games at higher resolutions, which is ideal for games like Skyrim, which have huge texture packs.

For gamers, a minimum of 1GB memory is recommended, although this must be weighed against other features of the card and the resolution at which you play.


Multiple displays can be supported by graphics cards, but the amount is limited by the GPU and the number of outputs available. Check with each graphics card to see how many displays it will accommodate.

SUPPORT FOR Production

A variety of output options are available for connecting graphics cards to monitors. You’ll need to purchase a video card that corresponds to one of your monitor’s ports. Many video cards will have two or three ports, and others will have four or more.

The VGA (Video Graphics Array) 15pin analogue link, also known as D-Sub, is the oldest and least powerful video connector. VGA ports are adequate, but other ports provide superior video quality.
DVI (Remote Visual Interface) – DVI-I (carries analogue and digital signals) and DVI-D (carries only digital signals) – DVI is a convenient connection between card and screen since it is used on most flat panel displays.

HDMI – Due to its speed and simplicity, HDMI is one of the most common connections. Both video and audio signals can be carried over HDMI.

DisplayPort – This link is gaining in popularity, and it can be seen in the next generation of displays. It has the ability to hold video, audio, and other types of data.
