NVIDIA MCP72 details leaked
Thursday 08th February 2007, 12:12:00 PM, written by Arun
DailyTech claims to have some new information
on the MCP72, NVIDIA's next-generation mid-range and high-end chipset
for AMD platforms. It will be NVIDIA's first chipset supporting
HyperTransport 3.0 and the AM2+ socket (which is both backwards and
forward compatible with the original AM2 socket), as well as PCI
Express 2.0.
MCP72 is supposedly NVIDIA's first single-chip solution in a while according to Dailytech, but that information is quite mistaken. The nForce 550 and nForce 570 are both single-chip solutions, based on the MCP55. The latter chip is apparently still on 130nm, and is extremely similar to MCP51; it has a few extra PCI Express lanes and a second Gigabit ethernet controller, but that's about it. The nForce 590 is also paired with a 90nm C51Xe, however, to add the extra PCI Express lanes necessary for 2x16 SLI.
Should Dailytech's information be taken literally, it would imply that the MCP72 has enough PCI Express lanes for 2x16 SLI by itself, at least when combined with PCI-Express 1.0 cards. It would then remain to be seen, however, how NVIDIA will differentiate the ultra-high-end model in order to add value to it. One possibility would be to simply use two MCP72 on the motherboard, much like the nForce 680a does for the AMD Quad FX platform.
