The specifications page for Itaniums shows that the Montecito chips (9000-series, such as 9050) do not support hyper-threading. However, the product brief that from 2006 (which seems to have disappeared from the website) showed that these chips did support hyper-threading. If I do a Google search, I can find numerous references to Montecito hyperthreading (in articles relating to the product launch or HP-UX). So is the specification page in error? Or did someone decide it doesn't count as hyper-threading since Montecito used SoEMT instead of SMT?
