Graphics Cards Explained
The Graphics card is an important piece of hardware that allows a computer to display images on the screen. It converts the information sent from the central processing unit (CPU) into pixels, or tiny squares of color that form images on the screen, and it determines how those pixels should light up to display the image. It’s not only for games: Many other types of programs require a graphics card to run properly, such as photo-editing and video-processing software.
There are two kinds of graphics cards: integrated and discrete. Integrated cards are built into the motherboard and are often included in computers as cost-efficient models, while discrete cards can be installed and upgraded independently from other parts of the computer.
GPUs are built for parallel architecture, meaning that they can process multiple data elements in the same way that CPUs execute single instructions. They are also able to process tasks in large numbers of threads, which makes them a good fit for the high-level processing required by data-intensive applications such as video analysis and translation.
For example, a GPU is used to process a number of images in a very short period of time to create a video or to render a 3D image on a computer screen. This type of computation can be much faster on a GPU than the CPU, and adding a card that has more processing power can boost performance. However, the amount of additional power that a GPU can provide is limited by the speed of its memory connection to the motherboard and the CPU.Graphics cards
