I'm not entirely sure about that. As we're basically talking
about two types of vulnerability here, I seem to remember that
one of them also affects "old enough" CPUs from the Pentium 4
era (before Core), in other words, when "HyperThreading" or
"HT Technology" arrived in Intel chips. But I'm not convenced
that I remember correctly. Further investigation should help.
