Given that the instruction set of AMD64 is defined by AMD originally,
while Intel was trying very hard to ram Itanic down everybodys
throat, that diagnosis is a given:  Intel copied AMD, and difference
in functionality is a screwup on Intels part, even if they documented
their screwup in their manual.

TL;DR: Which part of "compatible" doesn't Intel get ?
