No!  NO!  AMD core names does not mean the same as Intel ones.
Look folks, there is a clear way for this - the CPUID family.

K8 is Family 0Fh, the next major architecture is Family 10h.  *THAT* is
what is important to software optimization.  All the various AMD K8 core
names (Italy, Venice, San Diego, Manchester, ...)[*].  *Possibly* the
"hammer" core names, could be very slightly useful, but I'm not convinced
at that.

[*] not even the AMD's own software optimization folks know or use these
marketing dreamed up names.  The differences between these "city" core
names is important to the fab process folks, and the overclocking crowd.
