we introduce our readers with features only company that announced a family of new NVIDIA nForce 700i chipset for Intel platforms. Today you can be sure that the recent announcement of new technology NVIDIA 3-Way SLI for AMD platform was only a "warm up" before the current announcement.

Today, we are not able to give our readers the results of testing on the new platform chipsets, because the samples have not reached our laboratory. Nevertheless, we encourage you to review today with the "theoretical" details of chipset NVIDIA nForce 700i. It is worth it, because this time it is not limited to upgrade technology already known, and, in addition to details of the implementation of NVIDIA 3-Way SLI platform by Intel, for the first time today, you can learn a lot of interesting things about other innovations - such as new technology Enthusiast System Architecture (ESA), as well as a number of new functions for fine tuning to achieve maximum system performance.

Family sets logic NVIDIA nForce 700i for the Intel platform now includes two new chip MCP (Media and Communication processors) - nForce 780i SLI and nForce 750i SLI, unites them under the new certification of the availability of 45 nm processors from Intel kernel Yorkfield and Wolfdale; support tyres PCI Express 2.0, a full-fledged support DirectX 10 games in combination with modern GeForce graphics cards, including, in various configurations, NVIDIA SLI. At the same time, new sets of logic family NVIDIA nForce 700i significantly different set of functional capabilities. These differences immediately spoke eloquently positioning chipsets: while nForce 780i SLI is designed to create the most productive game systems technology 3-Way SLI version nForce 750i SLI is positioned as the industry's decision to support two graphics cards in SLI mode and fair price.


Chipset NVIDIA nForce 780i SLI MCP
Chipset NVIDIA nForce 780i SLI platform is the first solution to the components certified under the ESA project (more about him just below).

Chipset NVIDIA nForce 780i SLI is a set of logic that supports PCI Express 62 tyres, 32 of which - PCI Express 2.0, have twice the performance than the current common standard PCI Express 1.0. In practice, this means achieving a peak performance of 2.0 x16 PCIe configuration up to 8 Gb / s. Chipset NVIDIA nForce 780i allows you to configure these 32 tires as 2 × 16 or 4 × 8, or 1 × 16 or 2 × 8. The remaining 30 tires standard PCI Express 1.0 can be configured as a 16 × 1, 1 × 8 × 1 and 6.

In the future, 3-Way SLI Connector oidaetsya that, in addition to fees NVIDIA 3-Way SLI Connector, mode 3-way SLI can be realized through the use of three independent SLI connectors. Motherboards based on the nForce 780i and turnkey system with support for 3-way SLI will be equipped with such transitional fee.
The reasons, ultimately "gave rise" to light technology 3-way SLI, NVIDIA in the company, primarily known as an opportunity to realize the maximum available through its facilities in the modern games. For example, none of the currently announced systems on the basis of one or even two graphics cards has been unable to provide normal game Crysis high plants, while a system with 3-way SLI supporting DirectX 10 will provide the regime with a resolution of up to Crysis 1920 x 1200. Moreover, the old game - like Quake 4, you can now run with a resolution of 2500 x 1600 and the installation 8xAA, while productivity will reach 150 fps. In general, 3-mode way SLI to ensure adequate performance with a resolution XHD and 60 fps in the modes 8xAA or 16xAA.
Comparing the new technology 3-way SLI with announced in mid-2006 Quad SLI technology on two 2 - processor GX2 graphics cards GeForce 7900 or 7950 GX2, the NVIDIA note that, despite the rather high performance platform Quad SLI 3D games in many high-class end, for such systems have several limitations. In particular, the implementation of Quad SLI much more demanding corps to design PCs, and the total output of such a system would still be limited opportunities for DirectX 9, is not effectively able to download all four graphics processor. In this regard, technology 3-way SLI looks more "friendly" to the user, allowing a further upgrade to produce as required and with equally effective work as DirectX 9 under, and under DirectX 10, along with compatibility with a broader list of games.

Mode 3-way SLI activated by using NVIDIA Control Panel, which, in 3D Settings tab, it is necessary to establish a regime SLI.
NForce 780i chipset consists of three chips: nForce 780i SPP (NF780i-SLI), nForce 570 MCP (NF570I) and nForce 200 (NF200-SLI). Cheep NVIDIA nForce 200 is a PCI Express switch with one incoming port and four outbound ports. Outgoing ports in the NVIDIA nForce 780i SLI MCP, in turn, allow the port to configure the two PCIe 2.0 × 16 ports or four x8 PCI Express 2.0. Thus, the interface between NVIDIA nForce 780i SLI SPP and NVIDIA nForce 200 provides maximum bandwidth of up to 4.5 GT / s tyre - more than enough to ensure full performance graphics cards with PCI Express-bus 2.0.
