The nForce 700 is a chipset series designed by Nvidia first released in December 2007. The series supports both Intel Core 2 and AMD Phenom processors, and replaces the nForce 600 series chipsets. Several members were spotted, including the codenamed MCP72 for AMD processors and the C72 for Intel processors, launched with the name "nForce 780a" and "nForce 780i" chipsets respectively. Currently, the released variants are the 750i, 780i, 790i, and 790i Ultra.

Intel chipsets

nForce 7xx

The nForce 780i and 750i chipsets features the nForce 200 PCI-E bridge (previously codenamed BR-04) connected to the northbridge via a 4.5 GT/s proprietary bus. Its function is to implement the lack of PCI-E 2.0 support from the northbridge.^[4]
