The gang at HKEPC are saying now that Intel will be releasing a quad core Q6400 for a price under $450.  That’s the good news!  The bad: it isn’t planned until the third quarter of 2007.
Core 2 Quad Q6400 remains in Kentsfield core like others released models. Standards for this model include: 65nm manufacturing process, LGA 775 package, clock speed at 2.13Ghz, 1066MHz FSB, and  4MB x 2 L2 Cache. Core 2 Quad Q6400 also support for Intel ViiV, VT, EIST, 64 and Execute Disable Bit. Combining the performance provided and the low price, this would be a great rival for AMD’s AM2+ processors.

In addition, Intel’s native Quad Core, codenamed Yorkfield, is scheduled to release in the second half of 2007. The native Quad Core will introduce a 6MB L2 Shaded Cache, lower the latency between the cores. Besides, its FSB has upgraded to 1333MHz and will be fabricated in 45nm process.
