Powered by an onboard NV44 (6600 series) GFX core, NVIDIA are set to release an IGP edition of their latest nForce4 motherboard family. The Inquirer state that NVIDIA haven't disclosed an official name for the IGP chipset yet but it's current codename goes under that of the "C51G". By the looks of it, we should start seeing these variants pop up by the end of the first quarter next year.
NVIDIA WILL INDEED have an integrated graphic core for its Athlon Nforce 4 supporters. We are not sure about the final name as it's too early for that, but the chipset itself comes under the codename of C51G.
It's paired with a new south bridge codenamed MCP05. This means that if Nvidia wants to bring integrated graphics into Athlon 64 chipset segment it had to make a dual chip design. It will follow a traditional north bridge and south bridge design.
Nvidia will sample these chips in February while multiple production is expected in April. I guess we should be able to see boards based on C51G+MCP05 chipset at CeBIT 2005.
