You made to many assumption here. Based on what we know about bobcat architecture, it should be in range of athlon64 perf.
Lets see.
Bobcat:
2 decoders, 2 ALU+2 AGU (max 4 uops per cycle), 64-bit fpu (max up to 2 uops ).
Athlon64:
3 decoders, 3 ALU/AGU (max up to 6 uops per cycle) 64-bit fpu (max up to 3 uops per cycle).

here we go again....
