We told you a lot about Intel's new chipset planed for Q2 2008 but we figured out that it is better to show you the real picture. You can read the intro part here.
You can also see that Yorkfield and Wolfdale names are real and that the chipset supports DDR3 1333, 1066, and 800 MHz, as well as DDR 2 800 and 667. It also supports FBS 1333, 1066 and 800 MHz as well.
It has integrated graphics with display port, HDMI or DVI port or you can simply plug any PCIe 2.0 or older card.
The Southbridge known as ICH10 supports bunch of USBs, a lot of SATA ports a few PCIe ports and Intel HD Audio. Well just look at the diagram.
