NVIDIA 780i: Evolution Plus Triple SLI

nForce 750i Platform

The lower-priced 700i board is the 750i, an update to the current 650i chipset.

The 650i SLI has 18 PCIe lanes, which come from the SPP; the MCP does not supply any PCIe lanes. 750i follows the same pattern as 780i, with the SPP using the 16 PCIe lanes to communicate with the nForce 200 chip. The nForce 200 chip provides PCIe 2.0 compliant slots, but it is configured as one x16 slot and one x8 slot, where the 780i provides two x16 slots off the 200 chip.

This is an improvement over the 650i, which could be one x16 slot or two x8 slots. However, it is apparently not possible to split the 750i into three x8 PCIe 2.0 slots, for example, as the 780i can split into four x8 PCIe slots. Except for the added x8 PCIe 2.0 slot the port, slot and peripheral count remains the same as the 650i. 750i motherboards will not ship until January, so we will not have hands-on performance results for another 4-6 weeks.
