The PPC405 or PPC440 are nothing like the POWER5+, even if both are Power ISA v2.03. And likewise, the A2O is nothing like the POWER8, even if both are Power ISA v2.07. The modular way the Power ISA spec compliancy works (Books with optional parts and optional feature sets) makes the ISA revision mostly irrelevant for comparison of microarchitectures/cores.
So CPUs compliant to the same ISA don't understand the same instructions? Seems a bit more
complicated than I thought...
