Hard disks with interface serial ATA gradually obtained the possibility to work in case block without data transmission speed loss - the appropriate function ensured the external version of interface on name eSATA. As far as external video card are concerned, similar products already exist in the assortment NVIDIA Matrox: the first uses a special interface for the association of video card in the cluster of class quadro plex, and the second proposes the connection with video card on fiber-optic cable. Asus company recently presented external boxing for video card, connected to notebook through Express Card.
In a word, the attempts to make video card beyond the limits of system case were taken by producers many times, and under the conditions for a swift increase in the overall graphic card sizes and their level of energy consumption a similar idea began to attend series users. As reported associates , official certification organ PCI-SIG affirmed the specifications of PCI express external cabling 1.0, the describing standards for data transmission according to the external version of interface PCI express 1.1.
As always, detailed documentation on the new standard is hidden , but some data about the new interface are already known. First of all, in the present editorial staff it makes possible to transmit data with a speed of 2,5 Gbit/s, and in the future this speed can be increased to 5,0 Gbit/s.
Here are determined the port types and cables PCI express x1, PCI express x4 (on the photo above), and also PCI express x8 and PCI express of x16 (on the photo below). Port for PCI express x2 must be developed later.
The external version PCI express will be used not only for the connection of those external video card. The ports input-output, external data-collecting devices and different expansion card - all this can be connected through the external version of interface PCI express. we soon will learn, what propagation this version of interface will receive in the desktop segment.
