VR Zone is the second source to report that Intel has cancelled its 45nm Havendale processors. This was supposed to be one of the first desktop processors with integrated graphics but that honor will now go to the 32nm Clarkdale, which is basically the 32nm shrink of the Havendale.
Most likely, Intel is confident that their 32nm process technology is on target to enter mass production by Q1 2010 therefore a 45nm based processor will no longer be needed. This allows TDP to be reduced significantly since a 45nm CPU+IGP will churn out considerably amount of heat.
However, a 32nm CPU+IGP poses too much a challenge to get it out on time therefore Intel opts for Multi-Chip Package (MCP) for Clarkdale instead. The MCP contains a 32nm Westmere CPU and a 45nm IGP.
