Intel recently increased the number of 45nm-based CPUs it plans to launch for desktop PCs to nine, according to sources at motherboard makers. Within the nine CPUs, five will be dual-core processors (Wolfdale) and the remaining four will be quad-core (Yorkfield). All will adopt a 1333MHz FSB. Model numbers for the upcoming products are still undecided, noted the sources. 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
