Desktop Processors
On October 21, Intel will launch the 2.4GHz Core 2 Duo E4600. It will supplant the 2.2 GHz Intel Core 2 Duo E4500, which will be adjusted downwards from the current price of $133 to $113.
This puts the E4500 at the same price point as the 2.0GHz E4400. However, Intel does not intend to reduce the price of the E4400.
Intel will also reduce the price of the Intel Pentium 4 631 by $10 to just $59 in quantities of 1000. This is presumably the price for the final batch of the Pentium 4 631 as it is scheduled to be discontinued this month.
On December 2, Intel will introduce the Pentium Dual-Core E2200. It will be a 2.20GHz part priced at $84. Only in January 2008 will Intel reduce the price of the Pentium Dual-Core E2180. It will be pegged at the $74 price point which used to be occupied by the E2160. The Pentium Dual Core E2160 will also be adjusted downwards to $64, the same price point as the lowest-end E2140 model.
