The new NVIDIA nForce 4 SLI X16 chipset takes the same basic feature set of the hugely successful nForce 4 SLI and expands upon its PCI Express lane configuration, offering two full X16 graphics slots for dual graphics SLI configurations. This adds another 16 lanes to the chipset, as well as 16 additional 2.5G PCI Express SerDes (serializer/de-serializer) interfaces, which in turn adds to chip real-estate and pin count. As a result, in this incarnation, the nForce 4 SLI X16 has become a discrete two-chip solution for north and southbridge functionality..
