In addition to the Yorkfield Extreme Edition, other processors stemming from Penryn architecture should be available in the fourth quarter of 2007. However, these will exclusively be the Xeon Harpertown (quad core) and Wolfdale (dual core), which are meant to take over for the Clovertown and other Woodcrests. All of the Harpertowns will have a frequency of at least 2 GHz and the Wolfdale-DP will go as high as 3.33 GHz in its standard version. The existence of a Low Voltage version set at 3.16 GHz with a TDP of 40 Watts looks promising and these figures can lead us to believe that Intel has reasonable margins for increasing frequencies with its new architecture in the future.

	The Nehalem may not be the only Intel processor to arrive earlier than expected. The latest information from Intel confirms the appearance of a Yorkfield Extreme Edition at the end of 2007 ,which should be set at least at 3.33 GHz. The release of the other non « Extreme » Penryns will take place in the first quarter of 2008. Two other Yorkfields as well as four Wolfdales (all are dual cores) are also planned. While the frequencies aren’t yet known, we noted the existence of a version whose FSB is limited to 1066 MHz and L2 cache at 3MB, however, in which TXT (Trusted Execution Technology, AKA LaGrande) is absent. The following roadmap only takes into account the essential details. As for laptops, the Penryn will allow a much welcomed renewal for the Santa Rosa platform and this should also happen in the first quarter of next year. An Extreme Edition model is planned as well but it is curiously devoid of Intel Dynamic Acceleration technology. Higher frequencies and FSB are expected in the second quarter for the Montevina platform, accompanied by Cantiga chipsets, which will have (amongst other things) a FSB 1066 MHz and DDR3-800/1066 in addition to DDR2.
