The unlikely source this time is a Japanese website called 4gamer, but from what we can tell, the information appears genuine. One of the major missing pieces of the puzzle that has now been unveiled is that Intel will indeed have two different IGPs and the naming appears to be Intel HD Graphics 100 and Intel HD Graphics 200. Among the desktop processors, only the Core i7 2600 and i5 2500 will get the Intel HD Graphics 200 IGP. This seems like an odd move by Intel, as usually those that buy higher-end processors tend to also invest in a dedicated graphics card. The Intel HD Graphics 200 will have 12 execution units, while the Intel HD Graphics 100 will have to make do with six.
The entire mobile chipset line-up has also been revealed, which consists of the UM67, HM65, HM67, QM67 and QS67 chipset. We were unaware of the UM67 and this is meant to be an ultra-low power version of the other mobile chipsets. This is suggesting that Intel is still sitting on a lot of additional mobile Sandy Bridge processors which should arrive at some stage during the latter half of next year. Feature wise the UM67 is identical to the HM65, but with the addition of two extra USB 2.0 ports for a total of 14. All of the new chipsets will support Intel's Wireless Display technology if combined with the right Wi-Fi solution from Intel.
