Five of these will be dual-core Wolfdale processors and four will be quad-core Yorkfields. All of them will use a 1333MHz FSB. One of the interesting things is that these processors will feature an unlocked multiplier, according to Taiwanese sources Intel will allow you to increase the clock multiplier in steps of 0.5.
Four of the five Wolfdale processors will have core frequencies of 3.16GHz, 3.0GHz, 2.83GHz and 2.66GHz, while the frequency of the remaining one is unknown. All five Wolfdale processors will feature 6MB L2 cache, detailed the sources.
Three of the four Yorkfield processors will have core frequencies of 2.83GHz, 2.66GHz and 2.5GHz with the remainder as yet unknown. Three will include 12MB L2 cache while the 2.5GHz version will have 6MB.
