No, the first chips with hyperthreading were Xeons, and the first P4 with
hyperthreading was the 3.06ghz/533fsb Northwood P4, *well* before Prescott
was released. It was then in all the "C"/800FSB Northwoods.
Further, of the first-generation Prescotts, I believe HT was disabled in the
2.8ghz/533fsb and only enabled in the 800FSB models, but that may be mistaken.
