We choose a laptop. Discrete graphics card

The appearance in a huge number of compactThe laptops were provoked by the growing dependence of modern man on every day on the conveniences 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 attractivemobility, modern laptops on a number of parameters are inferior to stationary computers. 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 graphical information when solvingordinary office tasks, and when processing simple media files does not cause difficulties for almost any laptop. Even budgetary low-power netbooks are coping with these problems perfectly. But when the quality of graphics requires the use of additional capacities, many modern mobile PCs work excessively slow, and often simply refuse to operate in such a busy mode.

On the proceeds of an admirer of 3D graphics andCAD-designers come with a discrete graphics card. Graphics, built on the basis of this technical device, can improve the performance of the notebook. True, for the convenience of a discrete graphics card, you have to pay with an increasing level of power consumption, and the price of a 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. 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 isquite a significant addition, and its choice requires certain 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 "in the teeth"the latest games and three-dimensional graphics, adopted the marking * 900, * 850, * 800, * 700. 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 are nominal from * 000 to * 250, after 50, respectively. On such devices, work with the Internet, reading e-mail, launching office applications is available.
