NVIDIA announced the SLI technology in the middle of 2004, And towards the end of the year Has launched the nForce4 chipset family that brought the SLI message to personal computers. A few weeks later, the products themselves began to emerge, in the form of motherboards with two brackets for two video cards for the creation of the SLI array and the NVIDIA 2005 already stormed the market.
Today, about a year and a half after changing the face of the industry, with the advent of the SLI in PCs, NVIDIA plans to do it again, this time with two new technologies. One is SLI for mobile phones which we have already reported earlier Today and the second is the Quad SLI. For those of you who have wondered, this is not an 4 SLI but an 4 in SLI.
In fact, Quad SLI was first mentioned during the 2006 CES exhibition when Dell introduced the XPS 600 Renegade Which incorporates 4 GeForce 7800GTX 512 graphics processors. Today, this is the official launch of the Quad SLI array and also, the video card on which it is based is upgraded to GeForce 7900GTX 512. Apparently, the trade name of these video cards will be GeForce 7900GX2.
How does it work about? - Well, first of all, these are not 4 separate video cards, each of which connects to a separate holder on the motherboard, NVIDIA has chosen a way to do this. Each graphics processor is assembled on its own video card (PCB) when there are two types of video cards, primary and secondary. The main card is the one that connects to the PCIe slot and to which the secondary card is connected via a special connection that exists on it. Each video card has of course the SLI connection at the top and after installing the video cards on the motherboard connect the two main and secondary video cards using the SLI bridges. A much less concise explanation, with pictures and also explanations about the technology can be found HERE וHERE.
At this time, the technology in question is only available on complex systems such as those of Alienware, Dell and other companies in the Americas, Europe and Asia. So if you want to buy a pair of GeForce 7900GX2 graphics cards (each GeForce 7900GX2 is actually two GeForce 7900GTX 512 as we mentioned), you will not find them in the store. It is not inconceivable that later this year the average gamer will also be able to purchase such a video card and upgrade his computer in person, since in terms of motherboard all it takes is for it to be based on NForce4 SLI x16 chipset, When some argue that the version also SLI Normal will suffice.
If and when it is possible to purchase theGeForce 7900GX2 privately, be prepared to shed at least 8000 NIS only on video cards. Assuming you have a suitable motherboard, you will also need to be equipped with a suitable power supply, of about 600 watts and above which is approved and suitable for work under load that will create such a system.
