Feature cards in a laptop is that in the course of their work, it is quite hot. One of the main causes of failure of the video card in a mobile PC is a strong overheating of this device. Modern manufacturers in the development of graphics cards for laptops are forced to constantly balance between power and performance graphics card (and hence the degree of heating), compact size and battery life. Video card for a laptop can be divided into discrete and integrated. Integrated graphics cards require insertion into the GPU is one of the components of the laptop, in particular, chipset. Features integrated graphics are small and it loses much of its performance discrete cards, not to mention the video card for desktop PCs.
Such as video cards can memory enable the laptop, which reduces the cost of the mobile device. Integrated graphics cards are able to cope with office tasks, two-dimensional graphics and undemanding to chart games. They are proven for use in budget laptops or office. Discrete graphics cards deliver much better performance due to the presence of its own powerful graphic microprocessor. It was he who carries out the main processing image data, relieving the CPU of these tasks the notebook. Modern discrete graphics cards for notebooks is almost comparable to their performance with graphics cards used in desktop PCs. They consist of a graphics processor, video controller, responsible for forming the image in the video card, memory, and very special cooling system designed to remove heat from the heat-generating chip laptop.
