AMD plans to be ready with its 45 nm version of K10 in the second half of 2008 and it believes and hopes that this is enough to fight Nehalem.

Deneb 45nm will support the existing socket AM2+ and it will work in AMD 790FX and the rest of the 7x0 chipset family while you will have to chance the motherboard to make the Nehalem work

Deneb 45 nm quad core should come before Nehalem, as the latest roadmap we’ve seen indicates that Intel won’t launch its native quad core CPU until the very last Q4 2008.

We hope for AMD’s sake that Deneb will be out a bit sooner than that.
