Intel is prepping the release of three additional processors to their quad-core lineup, adding two Xeons and a single Core 2. Core 2 Quad 6600 will operate at 2.4GHz, and the Xeon 3210/3220 will operate at 2.13GHz and 2.4GHz. The latter are designed to be "low-end" server chips, and are geared around boards with only a single socket. The desktop Core 2 is expected to be previewed at the CES.
On top of extending the reach of the quad core line, Intel is also looking to keep prices low on the chips, at least lower than expected. The above mentioned 6600, for instance, will be sold at only $531 in quantity, rather than the $850 price tag originally estimated. A price drop of that much is sure to encourage faster adoption.
