FUD Zilla heard AMD's upcoming 45nm Deneb core won't go after Intel's Nehalem as the chip lacks the power to compete:
Our sources are confident that Deneb at 3.0GHz and even 2.8GHz should be enough to compete with the Core i7 920 (Bloomfield) that it’s clocked at 2.66GHz. Clock to clock AMD doesn’t stand any chance as according to all of the news we've gathered so far, Deneb can compete with Yorkfield on the same clock, i.e. the Core 2 Quad generation of CPUs, but not with Core i7.
The good news is that this might indicate that all Deneb cores will cost close to $300-400, if not less including the fastest clocked one. The Core i7 940 at 2.93GHz will sell for $562 and as you can imagine AMD’s 3.0GHz Deneb has to be priced lower than that as it will end up slower.
