Nvidia's anticipated next-gen Intel-oriented desktop chipsets - codenamed 'MCP73' - will debut on 25 September, it has been claimed by Far Eastern sources.

Motherboard-maker moles in Taiwan, cited by local newssite DigiTimes, claim that the chipset family will launch with five members - four with integrated graphics and the fifth without. The integrated parts will ship under the GeForce 7 brand as the GeForce 7050 and the GeForce 7150, each paired with either an nForce 630i, 620i or 610i.

The graphics-less chipset will simply be called the nForce 630i, the sources claimed. It will support Intel's 1333MHz frontside bus, as will the two products that also incorporate it: the GeForce 7150 nForce 630i and the GeForce 7050 nForce 630i pairings.

The other chipsets support a 1066MHz FSB. All of them connect to 800MHz or 667MHz DDR 2 memory in single-channel configuration - the latter a sign they will be aimed at entry-level systems, the moles claimed.

Past reports have pointed to a trio of MCP73s: two with on-board graphics and one without. The chipsets are again said to support HDMI and HDCP. Previously, what's now being called the nForce 630i will host up to four 3Gbps SATA drives and a single parallel ATA peripheral. It can run up to ten USB ports and has Gigabit Ethernet on board.

The MCP73 line is expected to be followed later this year by the MCP79, claimed to contain a GeForce 8-class GPU to allow it to support DirectX 10. It too will host HDMI ports and HD resolutions of up to 1080i. It will connect to the CPU over a 1,333MHz FSB.
