..
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 the
that 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.
