According to their information, which was passed on to the site by chatty motherboard manufacturers, Nvidia will launch an MCP73 integrated graphics chipset in the second quarter of 2007. The MCP73 will be an all-in-one chip, and it will include a G72-based graphics core (similar to the one in GeForce 7300 graphics cards) with HDMI output and HDCP copy protection support. Also among the MCP73's rumored specs will be a 1066MHz front-side bus, single-channel DDR2-667 memory support, PCI Express x8 and x1 expansion, support for four 300MB/s Serial ATA ports and one ATA port, and Gigabit Ethernet.
The MCP73 isn't the only Intel IGP on Nvidia's roadmap, though. Supposedly scheduled for the first quarter of 2008 is an MCP79 chipset that will include a GeForce 8-based graphics core and 1333MHz front-side bus.
