Techpowerup has a brief wrapup:
Here's a brief look at some of Intel's upcoming chips:Demotion of Core 2 Quad Q9550 to Mainstream. It leads the mainstream segment. This follows a significant price cut after the entry of Q9650. Core 2 Quad Q9400 enters the sub-segment of high-Mainstream. There are variations in the QuickPath interconnect bandwidth between the Core i7 2.66 GHz, 2.93 GHz parts with that of the extreme segment 3.20 GHz model. The extreme segment Core i7 seems to have a higher bandwidth QPI system interface. Lynnfield is on course, slated for Q3 2009. Two 3.xx GHz dual-core Havendale parts will take seats along with Lynnfied, definitively with 4 MB caches. One of them gets into high-Mainstream sub category. Havendale parts make it even to essential and value classes with the low-end value parts continuing to be based on Core architecture till a little longer. A six-core Nehalem part code-named Westmere comes out in 2010.
