You can expect to see better performance in SPEC_CPU for Shanghai vs. Barcelona when comparing identical clockspeeds. But of course the increased clockspeed ist a big argument for Shanghai (or the same clockspeed with less energy consumption). 

And Shanghai has some more features like faster memory and HT3 in some of the later revisions i hope...
