The development of computer technology, the rapid spread of the Internet and the capabilities provided by its means, presents new requirements for personal computers. Along with bulky systems intended only for stationary use, mobile compact devices such as laptops and, more recently, inexpensive netbooks are increasingly appearing in the everyday life of ordinary users. Along with the attractive qualities of increased mobility and relative non-volatility provided to the user, these devices, despite the abundance of properties attractive to the average user, have a number of drawbacks. The most important minus of compact devices is the price, which in terms of computer power is much higher for a laptop than for a desktop computer.
Gamers and other admirers of 3D effects are especially affected by this. The vast majority of owners of laptops equipped with an integrated video system, dream of expanding the capabilities of their compact PCs. An original technical device, such as an external video card, is the logical solution to this problem. Only through the use of modern technologies, the main manufacturers of personal devices for a wide audience of users have already begun to develop and produce serial samples of technical devices that expand the graphic capabilities of laptops.
An external video card is an independent device that connects to a laptop and an additional monitor. In this design, the mobile PC acts as a regular system unit. The disadvantage of this technical solution is that the mobility of the laptop is lost, an external video card does not make sense on the road.
ASUS device - ASUS XG Station has a rather attractive appearance, individual power supply and its own display to display various information. The user can monitor the fan speed, control the GPU heating temperature, the number of frames per second and other technical parameters. The cost of this device is quite significant, and it connects to the Express Card slot.
Appearing a little later, AMILO GraphicBooster is more generous with the wallet of potential buyers, but it has increased opportunities, only you can use it only with AMILO Sa 3650 PC, only because it is the only representative of this family using
an AMD processor. The external AMILO GraphicBooster graphics card is compact and has advanced functionality, through which you can connect up to four displays at the same time.
The external usb video card from Kuroutoshikou looks more democratic, when you select it, you only need to figure out the DVI and D-Sub interfaces used by the external monitor. The device works correctly with the Pentium III processor at a frequency of 1.2 GHz, with 512 MB of RAM.
In the future, the appearance of new graphics accelerators is expected. The best option is a universal card that works with all personal PCs. It is possible that in the future, an external thunderbolt graphics card will become the most promising connection interface for additional devices.
