Technical field

The present invention relates to computer fittings technical field more particularly to a kind of independent display cards that multiple GPU are worked at the same time.

Background technique

With the development of modern processors technology, in interconnection field, it is using high-speed-differential bus substitution parallel bus Trend of the times.Compared with single-ended parallel signal, higher clock frequency is can be used in high-speed differential signal, thus using less Signal wire, the bus bandwidth for needing many single-ended parallel data-signals can be only achieved before completing.PCIE(peripheral Component interconnect express, high speed serialization computer expansion bus interface) it is bus interface of new generation, It uses at present popular point-to-point serial connection in the industry, shared parallel compared with PCI and the computer bus of more early stage Framework, each equipment have the dedicated connection of oneself, do not need to entire bus request bandwidth, and can be data transmission rate It is increased to a very high frequency, reaches PCI (Peripheral Component Interconnect Peripheral Component Interconnect mark Quasi- interface), the high bandwidth that the interfaces such as AGP (Accelerate Graphical Port accelerated graphics interface) cannot provide.

Video card is personal computer important component, and purposes is will to show that information is turned required for computer system Change driving display, and provided line by line or interleaved signal to display, control the correct display of display, independent display card because GPU (Graphics Processing Unit, graphics processor) possesses the bandwidth and working frequency of superelevation, and is equipped with individual Video memory is specially rendered and is calculated to image, and better display effect and runnability are capable of providing, continuous with technology The operation of development, HD video, large-scale 3D game picture special efficacy and special server can only be completed by independent display card, this is just It is required that the graphics rendering techniques of independent display card and graphics calculations ability are higher and higher.

Desk-top mainboard currently on the market, which is substantially to arrange in pairs or groups one piece using a PCIE interface, only has the only of a GPU Vertical video card work, as shown in Figure 1.Although the GPU performance of independent display card is being continuously improved, an independent GPU has the ability always Limitation is unable to satisfy higher performance display output and graphic operation ability.In order to meet performance requirement, many users have to select Another PCIE slot occupied on mainboard is selected, works at the same time multiple video cards, although this way improves the calculating of video card Ability, but the problem of bringing is must to use additional PCIE interface, and the area of the mainboard as shared by PCIE interface is larger, and The desktop computer mainboard of standard generally only has 2-3 PCIE interface, while the peripheral hardware of other standalone features currently on the market PCIE interfaces are used, if having to realize more video card work, will certainly just sacrifice original some functions, this is to use Bring very big puzzlement in family.Although some users meet the needs of more peripheral hardwares, bring by increasing the area of mainboard Problem is that finished product box body product is big and heavy, and due to being special designing, cost is often very high, more than the energy of consumer Power tolerance range.
