The introduction of the most recent NVIDIA chipset with integrated graphics for the Intel platform has been expected for quite some time. Code named the MCP7A, news of the chipset goes back to the middle of 2007 when we actually thought we would see it before the end of that year. Obviously some delays happened, either on the technical or legal side of things, and the product was delayed long enough for us to be writing about it officially for the first time in October of 2008. In fact, it is that delay that actually gave AMD's 780G chipset the IGP edge; but that isn't exactly relevant while we are talking about Intel-based platforms today.
