Bottom line: it's a business decision. Code generated by the Intel compiler "works" on AMD chips, although it may not be optimal. For Intel to support the optimal codepaths on AMD chips would require a substantial amount of research. I don't think they're intentionally crippling AMD chips; just declining to invest the effort to support them optimally.
