As with all rumors, please take the following news item with a grain of salt until we can receive official confirmation or denial from Intel.
It seems that AMD might have a few more months to get their high-end Phenoms ready as it's being whispered that Intel is going to hold back volume shipments of the QX9770 until the Feb-March time frame.
“The quad-core 3.2GHz QX9770, which will be available at US$1,399 in thousand-unit quantities, is to replace the Core 2 Extreme QX9650 processor launched in November 2007, the sources noted.
However, Intel is yet to phase out the 3.0GHz QX9650 despite the planned launch of the QX9770, said the sources noting that the two quad-core CPUs will be available simultaneously, although the 1k-unit price for the QX9770 will be US$400 higher than that for the QX9650.”
This could be a technical issue, but it's more likely a business issue. After all, if you already make the fastest desktop CPU on the planet, why release a new one unless buyers all dry up for your existing flagship? On the other hand, Intel should have learned their lesson about not taking AMD seriously by now.
