Types and how the graphics card works today
As technology advances due to the boom in evolution, higher- quality and higher- quality processors are required, today we will show you how the GPU or simply the graphics card works.
As its name suggests, this component is essentially responsible for processing the graphics of a computer system. Something that draws much attention to gamers, who know a lot about the latest models to have the most power in their new or renovated PC.
Currently, there are two very modern types of graphics processing, depending on how they are implemented on the GPU.
Dedicated cards
This type of graphics unit is the one that provides more power to your computer. As the name implies, they are designed to compulsorily fulfill only the assigned tasks, making them much more efficient. What characterizes a graphics card is the power of its chip (Si Pascal, Vega…) and the type and size of its memory GDDR5, GDDR5X or HBM, so it can only be used by itself.
Integrated graphics or IGP
Unlike dedicated cards, these are designed internally alongside the processor. That is, it is all encapsulated on the same chip. The IGP are considerably less powerful than a low or mid-range graphics card. It is very common to find processors with integrated Intel Iris graphics cards or AMD's fantastic APUs on PC. While other devices such as Smartphone or tablets incorporate their graphics together with the processor.
How does the GPU work internally?
Internally, this coprocessor works in partnership with your computer's processor, lightening the information load of the latter so that it can do its work more efficiently. Remember that the GPU works only with graphics, lightening the information load of the CPU. So both would be essentially processors, only with clear differences. For example, programs like Adobe Premire Pro CC benefit from using CUDA graphics card technology to maximize performance. For example, what used to take 40 minutes, now takes 8 minutes?
The main difference in the architecture of each one, despite the fact that the GPU is designed to calculate graphic information, being more prepared than a conventional processor, however when it comes to performing tasks, they are not as good. Although many are also used (especially AMD) for mining bitcoins.
Another of the most interesting points to know is the use of the antiliasing filter. What is it for? Basically it combines different points that have been calculated to represent a final image on your screen. Thus improving the quality of the image.
So what is Rasterize an image? Each triangle performs a check that corrects the pixels that make it up. That is, we will have a buffer and a triangle that will show that point.

Going a little into the history of graphics cards …. One of the first graphics cards to go on the market was Intel's iSBX 275 in 1983, making it one of the first computers to work with GPUs. Since then there has been an invaluable amount of capacity enhancement in these co-processors. Mythical graphics were the famous Voodo 3DFX, the GT8800, the GTX 480 heaters or the recent GTX 1080.

The evolution is so great that ultra-thin laptops with high-performance desktop graphics cards (GTX 1060, GTX 1070…) are being seen in chassis just a few mm high. Graphics cards are key today in Gaming and heavy information tasks. And is that we consider the processor a car and the speed of the graphics like that of an airplane?
