Intel 6xx & 3.73GHz EE Processors

@ 2005/02/20
Intel has made several key changes to the IA-32 architecture to allow for these 64-bit applications, such as adding support for 64-bit linear addressing. Variations of the IA-32 architecture may not offer full 64-bit linear addressing, such as the processors we’ll be looking at today which offer support for 48-bit linear addressing. This issue will be covered in a more detailed nature when we discuss the memory organization under 64-bit mode.

Trying to sell this processor to someone with the knowledge of the performance difference between the 6xx series and it would be like trying to sell the idea to someone that the world is flat.
Some of us do believe the world is flat.
