Video Cards
The main function of a Video Card is to process and display pictures on our screen. Video cards act as middlemen working between the processor and the monitor. The processor computes and determines what you are going to see and with the Old Video Cards, the processed images are translated to the monitor for display. These Video Cards were acceptable for a certain period of time, until a more graphical version of operating systems came into the scene, emphasizing on windows graphical processing. At such, there was a need to upgrade the video Cards.

To clear this bottleneck, companies began making cards called accelerators. In fact, Windows was such a driving force behind the development of accelerators that they became commonly known as Windows accelerators. These were video cards with added intelligence to enable them to do much video calculation that had previously been done by the processor. The accelerator can be highly customized and tailored to this specific task, giving you more efficient results than the processor.
The off-loading of this video calculation work has led to a many-fold increase in the power of the video subsystem in a modern PC. All modern systems have modern video cards with incorporated acceleration, some of which are very sophisticated. In essence, notebook video cards can be considered coprocessors working with the main CPU. Modern video Cards contain memory of their own and this function helps to reduce the work of RAM. With laptops outselling desktops, video cards for laptops are becoming very popular. In fact, laptop video cards are the most competitive computer component in the PC market these days. NVIDIA and ATI have very wide selections of laptop video cards. In case you need to upgrade your laptop, both NVIDIA and ATI are selling the latest video cards for laptops in the market. |
