The appearance of a huge number of compact laptops was provoked by the increasing dependence of a modern person every day on the amenities and the mass of attractive features, constantly improving computer technology, as well as Internet services seductive in their comfort. The laptop has ceased to be an element of a representative image; it has taken its natural place in the student's bag, in the traveler’s car, in the portfolio of the manager who is constantly on the move.
Despite its compactness and attractive mobility, modern laptops are inferior to
stationary computers in a number of parameters
. Achieving the functionality available to the computer familiar to us, as applied to a mobile device, sometimes 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 assistance.
Displaying graphic information when solving ordinary office tasks, and even when processing simple media files, does not cause difficulties for almost any laptop. Even budget low-power netbooks do an excellent job of this. But when the quality of the graphics requires the use of additional power, many modern mobile PCs work too sloppy, and often simply refuse to function in such a stressful mode.
To the rescue of fans of 3D graphics and CAD-designers comes a discrete graphics card. Graphics based on this technical device can improve the performance of the laptop. True, for the amenities that a discrete graphics card provides, you have to pay with an increasing level of energy consumption, and the price of the laptop does not stand still, but rises up. Nevertheless, thanks to the discrete graphics, the capabilities of mobile laptops and stationary devices are equalized.
What is a discrete graphics card, it is easy to understand, a little understanding of
the computer device. Initially, mobile PCs used integrated graphics, which is a graphics core integrated into one of the components. A 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 choosing it requires certain knowledge. Often, when searching for a PC with the most powerful discrete graphics, they are guided by the principle "the higher its number, the more powerful it is." Moreover, this method can lead in the wrong way. For example, the Radeon HD 4650 variant is much more productive than the discrete Radeon HD 5145 graphics card .
For the most powerful video cards, which are "tough" with the latest games and three-dimensional graphics, the marking * 900, * 850, * 800, * 700 is accepted. The middle level is marked * 470, * 450, * 400, * 350, * 300. The graphics on these graphics cards are used on home laptops for entertainment. The initial level of video cards is characterized by ratings from * 000 to * 250, after 50, respectively. On such devices, access to the Internet, reading email, launching office applications is available.
