SLI bridge important

Hi all,

VIDIA SLI technology is "Popular Science" magazine as the best innovation of 2004, "Popular Science" magazine editor Mark Jannot said, "These awards honor innovations that not only affects the way we live today, and changed our way of thinking about the future. "GeForce 6 system products from inception, a number of new graphics technology combined with high efficiency of the super scalar core architecture design, bearing on the ultimate visual processing of a major mission. Can anybody that why SLI bridge is important. Please reply.

SLI technology is through the series with two PCI Express graphics interface, and then two graphics cards to work together to improve the display performance of the entire system. SLI technology that will carry two graphics chips, graphics nVIDIA into motherboard PCI-EX16 also two slots, then connect card with an SLI linking two graphics cards in this connection to transfer digital signal processing card End of frame data is set up treatment, then the signal is output as a whole. To ensure the division of tasks and two graphics cards to work together, nVIDIA SLI control functions will be directly integrated into the GPU chip, the chip card for the connection and collaboration, it will render the task assigned to the two graphics processing, then processing the results collected through its operations and re-synthesis, high output full screen graphics. Check and reply.

Avtually the two graphics cards are not the same job, one of the card as a master card, another card as a deputy, Vice card which is receiving the mandate from the main card-related processing, and then pass the results related back to the main card, the two graphics cards are PCI-E interface, by connecting with the motherboard, which is two graphics cards also have a communication between the PCB card (that SLi bridge card). That is, source of data to be processed through the PCI-E slot obtained from the motherboard, while the processed data is carried out by connecting the card to transfer. Check and reply.

Lot of support and then the graphics card, mainly to see whether the motherboard supports. We say it is not a generation can not crossfire. With future products on the DDR3 is not mandatory we must have the same memory frequency can exchange of fire, now there are smart cards, and can be mutually compatible, DX10 is not in the past within the scope of this discussion. Need to tell you that would rather pay for a powerful graphics card does not do crossfire, because performance expectations are not high. Now the development of fast graphics card, four fights on the introduction of this machine card machine was scolded more miserable you can get to know the next. But do not support crossfire card is specified, you can product description knows quite well. Check and reply.

SLI (Scalable Link Interface or exchange scan mode) allows multiple graphics chips also work to achieve higher performance. Senior players should remember the 3DFX debut VOODOO2 SLI, through a dedicated data line will be two of the same brand VOODOO2 connected 3DF provide top performance at that time. Although the same two graphics cards to work simultaneously, but the introduction of SLI technology nVIDIA and 3DFX's SLI technology in fact different, VOODOO2's SLI graphics card through the two were responsible for the rendering of even and odd frames, and graphics to reduce the burden, improve performance purpose; and nVIDIA's SLI technology, When two graphics cards via an external connector of the connecting bridge, the driver can automatically identify the configuration and enter the "SLI Multi-GPU" mode. In the "SLI Multi-GPU" mode, the driver will be two graphics cards configured as a stand-alone device: that is, all the graphics processing of these two graphics chips as a separate logical device. Check and reply.

Although not the first one to support nForce4 SLI chipset, but Intel's (E7525) motherboard are workstation / server class motherboard, so the current level home users to set up SLI system, generally using nForce4 SLI chipset motherboard. Perspective on the current situation, SLI very bright future, nVIDIA SLI ready for launch to support the nForce 5 Intel chipset, and VIA, SIS will also introduce the so-called Dual PCI GFX technology, just wait for the nVIDIA just nodded. Therefore, based on the present situation, to set up SLI platform, using nForce4 SLI chipset is the choice of most players. Board of High-Speed Digital Interface is used to connect two graphics cards, without its help, SLI system is not formed. All the best.
