According to Xbit-Labs's sources Intel has already send some samples to its partners of the Pentium 4 3.06GHz, so they should be able to deliver the sufficient quantity of such CPUs when they are announced on the 14th of November :
From the various sources I received numerous confirmations about the release date of the Pentium 4 3.06GHz. Apparently, Intel will unveil its new processor on the 14th of November 2002, just a couple of days before Comdex Fall 2002 starts.
Intel’s Pentium 4 3.06GHz is the first Intel’s processor for desktops that supports the HyperThreading technology. I should once again remind you that the newcomer will only work on the new mainboards that can provide enough power for it. These mainboards meet the latest guidelines from Intel and are mostly based on the i845GE, i845GV, i845PE and Granite Bay core-logic devices. In order to take advantage of the HyperThreading technology, your mainboard should be powered by either one of the mentioned chipsets or utilise the latest North Bridges from VIA or SiS.
