Well-informed sources have confirmed that Shanghai K10.5, a 45nm version of AMD’s native quad core, and it will be about ten to twenty percent faster than the current K10 at 65nm. This is a clock per clock comparison and this is just as much juice as AMD needed to run faster than Core 2 Duo and Quad.
Our sources believe that this will be just enough for Deneb 45nm CPU to end up faster even than Penryn.
From the current schedule it looks that Shanghai generation 45nm Phenom should surface before Nehalem.
