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. -- -- David (obrien@FreeBSD.org) Q: Because it reverses the logical flow of conversation.
