A french site found some details about NVIDIA Nforce 4 chipsets. There will be 4 different versions of this chipset.
The Nforce 4 will be the entry level chipset. It will be a good performer but it won't feature high-end specifications.
The Nforce 4 Ultra adds some stuff as S-ATA II and 3 Gbit/s transfer. Hard drives sporting this should be ready around them. This chip will also include firewall options.
The third will be the Nforce 4 SLI which will offer dual PCI Express slots, allowing you to use NVIDIA's SLI.
Finally there's the Nforce 4 Pro which has support for two Opteron CPUs. This chipset will be used for the workstation and server market.
The first samples of these chipsets should be ready at the moment for manufacturers.
