ASUSTeK has decided to follow Gigabyte on the nForce chipset combination path to provide a multitude of PCI Express lanes.
The A8N32-SLI Pr expected at the end of the month will include an nForce 4 “C51D” (derivate from the C51G without the integrated graphic part) and an nForce 4 SLI … Southbridge. Both chips connect via the usual HyperTransport bus. ASUSTeK will provide a total of 40 PCI Express lanes. 32 will be attributed to the two PCI Express x16 slots, 2 to the integrated network and SATA RAID Marvell & Silicon Image chips and 4 to an additional PCI-E x4 slot.
The nForce C51D seems to be especially dedicated to this type of configuration and NVIDIA probably pushes this chipset couple to be integrated by other motherboard manufacturers to have “32x SLI” configurations. Now, we will have to find out whether if this PCI Express slot profusion will be really useful. In 2x8, graphic cards performances in SLI don’t seem to be much restricted by the PCI Express bandwidth.
In fact we feel that it is mainly the possibility to couple graphic cards without SLI connector (recently available from the ForceWare drivers) which will benefit the most from these additional lanes. We will also have now to wait and see if NVIDIA will make this functionality really useful with for example the possibility to couple two different graphic cards.
According to The Inquirer, NVIDIA will release soon a GeForce 7800 GT additionally to the GTX, to add to the GeForce 7 range. The only differences between the 7800 GT and 7800 GTX would be the new version lower frequencies and price.
The 7800 GT chip will be the G70 and not the G72 seen in the last non official ForceWare drivers. We remind you that the first documents to be released on the GeForce 7800 GTX mentioned 7800 GTX, 7800 GT and 7800 versions.
