We choose a laptop. Discrete graphics card

The appearance in a huge number of compact laptops was triggered by the growing dependence of modern man on the convenience and mass of attractive opportunities, constantly improving computer technologies, as well as the Internet services tempting with its comfort. The laptop ceased to be an element of a representative image, it took its natural place in the student's bag, in the traveler's car, in the portfolio of the constantly in motion manager.

Despite its compactness and attractive mobility, modern laptops are inferior to stationary computers in a number of parameters . Achieving the functionality that is available to a computer that is familiar to us, sometimes with a mobile device, causes a number of technical difficulties. Often a number of problems are solved through the use of externally connected devices, but even they do not always provide full-value assistance.

Displaying graphic information when solving ordinary office tasks, and when processing simple media files does not cause difficulties for almost any laptop. Even budget low-power netbooks are coping well with these problems. But when the quality of graphics requires the use of additional capacities, many modern mobile PCs work excessively slow, and often simply refuse to function in such a busy mode.

The discrete graphics card comes to the aid of 3D graphics admirers and CAD-designers. Graphics, built on the basis of this technical device, can improve the performance of the notebook. True, for the convenience provided by a discrete graphics card, you have to pay the rising level of power consumption, and the price of the laptop does not stand still, but rushes up. Nevertheless, it is thanks to the discrete graphics that the possibilities of mobile laptops and stationary devices are equalized.

What is a discrete graphics card is easy to understand, a little understanding of the computer's device. Initially, the mobile PC used built-in graphics, which is a graphic core, integrated into one of the components. The discrete graphics card itself has a powerful graphics microprocessor. In addition, it has a certain amount of RAM.

A discrete graphics card for a laptop is a pretty significant addition, and its choice requires some knowledge. Often, when searching for a PC with the most powerful discrete graphics, the principle "the higher its number, the more powerful it is". In this case, this method can lead the wrong way. For example, the Radeon HD 4650 is much more productive than the discrete Radeon HD 5145 graphics card .

For the most powerful video cards, which "the teeth" of the latest games and three-dimensional graphics, the marking * 900, * 850, * 800, * 700 is adopted. The average level is marked with * 470, * 450, * 400, * 350, * 300. The graphics on these video cards are used on home laptops for entertainment. The initial level of video cards is nominal from * 000 to * 250, 50, respectively. On such devices, work with the Internet, reading e-mail, launching office applications is available.
