I'd be shocked if that figure is absolute and not per clock basis.The Nehalem core is much much bigger than Penryn's , there are tons of extra stuff in the core. ( 22mm2 to 29.6 mm2 , that's a 35% increase while HT takes 5% ).
IMO , I'd expect it to give Penryn a severe beating in single threaded stuff while trashing it in multithreaded multicpu scenarios.
Intel Vice President Kirk Skaugen said thethat the CPU core performance jump from the same process Core 2 (Penryn) to Nehalem would be higher than the jump for Netburst to Core 2 itself.

Remember that Nehalem is the creation of Intel Oregon , the creators of Netburst.The original Nehalem was Netburst taken to extremes , multipipelined , multithreaded everything.
I'm pretty sure some of the stuff created there got into Nehalem v2 too.
