Intel has begun the process of ridding itself of an entire generation of 65nm Core processors, to pave the way for 45nm 'Penryn' Core 2 chips, due to begin appear in November. Marked for termination: all the Core Solo and Core Duo CPUs.

The Core Duos for the chop run from the 1.66GHz T2300 up to the 2.33GHz T7200, along with the low-voltage Core Duo L2500. The ultra-low voltage 1.06GHz Core Solo U1300 is one the end-of-life list too, as are the Core Solo T1300 and T1400, clocked at 1.66GHz and 1.83GHz, respectively.

In addition, Intel also told its customers they soon won't be able to buy Celeron M 400 series chips, specifically the 420 through to the 450.

Orders for these chips will be taken after 31 October, but customers will not be able to cancel. Intel will take no further orders after 31 December. Depending on demand, the parts could be leaving the chip giant's factories through to 6 March 2009, in the case of tray-mounted Cores and 7 September 2008 for tray-packed Celeron Ms.

Last week, Intel cut a range of mobile processor prices, added the new Celeron M 500 series and introduced the first Core 2 Solo chip.
