Graphics cards

The graphics card is a component in the computer that takes care of the image on the screen and calculates how to place the image on the screen. The more powerful it is, the faster it does this on higher screen resolutions.

Graphics cards work with a parallel connection (parallel computing), which means that they use thousands of cores to calculate complex mathematical calculations that display the image on the screen. Graphics cards also have their own RAM (random access memory), on which they can store the data it uses.

Graphics cards consist of a video BIOS, a video processor, video memory, a digital-to-analog converter, a bus connector, and video drivers.

There are three types of graphics cards. The integrated graphics card in the processor is the worst and is usually found in laptops. Then there is another one integrated into the motherboard, which is slightly more powerful and is already used in desktop computers, but still dominates among laptops. The third type of graphics card is discrete, which means that it is installed in a desktop computer via a bus on the motherboard. These graphics cards are designed for desktop or desktop computers and can be extremely powerful. Their only weakness is that components can overheat, and fire safety is also proven by many cases of new very powerful, and expensive graphics cards, which I will not mention to preserve the reputation of companies, whose graphics cards caught fire.

Graphics cards are powered via the motherboard, which has a special connector for powering graphics cards. The card then comes with an additional short cable that plugs into this connector.

Graphics cards can be cooled in a similar way as the processor, with the help of fans that cool the aluminum or copper plate. This plate is attached to the main parts of the card that heat up the most, with a thermal paste in between. The thermal paste ensures that there are no air pockets or holes between the cold part and the warm part, which would reduce the transfer of cooling. Then there is water cooling, which uses cold water instead of fans, which in the same way cools the aluminum or copper plate attached to the warm parts of the card. Water cooling is more efficient but also more expensive. Both types of cooling may, but not always, be in use at the same time.
