According to this report, Intel has decided to pull the plug on the 45nm CPU/GPU combos that were due out in 2009 known as Auburndale and Havendale.  These were going to be two-chip parts: one that included a dual-core HyperThreaded CPU the other chip a GPU. 

Now instead Intel is going to wait for the 32nm process and move Arandale up 6 months or so into early 2010.
Auburndale was supposed to debut on market as 35/45W mainstream and business notebook processor, while Havendale was the desktop versions, consuming as much as 75W (higher clocks). But, the economic crisis played its part and Intel isn’t so interested in keeping the 45nm production alive for these two parts. 45nm production will be kept in place for Pentium and Core 2 Duo/Quad processors for the mainstream crowd, and Core i7 for those on higher end of scale.

But, this is not the end of Fusion concept in Santa Clara. Intel is going to replace Auburndale/Havendale with their 32nm die-shrink, known as Arandale. Arandale was originally supposed to debut for Back to School season 2010, alongside 32nm quad-core and sexa-core Westmere processors (Core i7 die-shrinks). But now, Arandale core has been brought forward by six months to Q1′2010. The debut is set probably for March (can you say CeBIT?) timeframe. We don’t have any piece of information on Arandale, besides the fact that it is a die-shrink and will probably feature larger L3 cache, probably somewhere in the range of 6MB, just like current 45nm Wolfdale processors (6MB L2 cache).
