Source : DigitimesIntel will soon be discontinuing production of its oldest processors. So, the majority of Core Duos will be declared end of life in the coming months.
The Core 2 Duo T7300, 7400, 7200 and the other at a 667 MHz bus will also be discontinued in March 2008.
However, these processors are the only ones which can be installed in a Mac mini or an iMac that originally shipped with Core Duos. Indeed, the most recent 800 Mhz bus ones will be incompatible.
Note that this bad news hides a good one. Apple will soon be obliged to move the MacBooks and Mac mini Core 2 to Santa Rosa, as these machines also use processors at a 667 MHz bus.
