Since the launch of the computer, work has been done over and over to improve people's experience of using it. If you are a computer lover and are very interested in any knowledge about them, this term will not be something new to you.

And even if not, for those who are building their knowledge in relation to them by reading this article they can. I assure you it will be very useful. One part is there  PC GPU or graphics processing unit, What are? Read on to learn.



What is the GPU?

How could you read in the title this is the graphics processing unit of the pc, but what does it mean? It is a coprocessor dedicated exclusively to the processing of computer graphics. The market leaders in the production of these processors are AMD are NVIDIA and Intel.

So there is a better efficiency of the equipment thanks to it and the effect is evident in the processing speed. That's why you can activate the dedicated GPU video card to play on your PC. However, although the GPU can perform this procedure more efficiently, it will never supplant the CPU as a central processor, as it is not designed for this.

 How does it work?

La But by the full GPU acceleration tech it has several processing cores, but performs its functions with low clock frequency. This processes the data received from the CPU through internal procedures, calculates the values ​​that must be stored to be processed later.

It performs a process of transforming the values ​​in a row and in this way outputs a signal to the monitor to reproduce the graph. It now has two main functional units, one for vertex processing and one for pixel processing.



Vertex processing

It processes the information of the graphic vertices obtained by the CPU, this is because although it is processed by the CPU it needs adjustments. After getting the information, what the GPU does is process the rotation, rearrange the visible space at graphic level. All this is done so that the graph can be visualized in a better way and proceed to the pixelization of the image.

Pixel processing

This procedure is somewhat complex, this is when the graphic information, the levels and effects needed for a realistic picture. Then through this process the graph is brought to the screen where after concluding we can see the final image.

GPU acceleration

With GPU acceleration you can achieve higher and better performance, as well as lower power consumption. You can do much better graphics or video conversion by using GPU accelerated encoding. All thanks to a joint work of the CPU and GPU, in this team the CPU performs the least forced work.

While the GPU does the work of analyzing the areas of the process in which requires more attention for accurate calculations. Therefore, thanks to this, it will seem that inside the computer everything is done much faster.

Differences between GPU and CPU

Despite the fact that both the CPU and the GPU perform the data processing function. The GPU performs the calculations on the graphics as it was designed specifically for this function. The CPU is the processor with a general purpose, it can do all kinds of calculations, thus working with graphics.


On the other hand, both the GPU and the CPU have a substantially different design to perform the procedures assigned to them. The GPU is designed to perform more functions in parallel.

While the CPU is running serial processing, has fewer cores and performs few functions in parallel. Find out how to find out how big your screen is in inches or pixels in the following article.
