|The Pentium V is likely to fly along at between 5GHz to 7GHz, have 2MB plus of level two cache, be built on a 90 nanometer process, and have a stackable design.
According to this source, and the details have not been confirmed, a module sitting on top could provide 64-bit extensions.
And the source claimed, Microsoft is ready to launch a version of Windows called Elements with 64-bit extensions.
The idea seems to be that people can buy a 32-bit module, and then add in the 64-bit processor.
At the end of the article their is something very doubtful, that the Pentium V could have an FSB of as much as 4000MHz, or it could also be reserved for another and later coming cpu from Intel, the Nehalem which is rumoured to come in 2006.
I think they accidentily wrote a zero too much, currently Intel his CPU's have an FSB of 200MHz (800MHz Quad Pumped).
