I think he means s.th. related to the problem of the virtualisation of 
the i/o that the AMD-CPUs should do better than the first 
Intel-implementation of VT.
AMD calls this "AMD I/O Virtualization Technology (IOMMU) 
Specification", you find a PDF here: 
http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/34434.pdf
The "Intel Virtualization Technology for Directed I/O (VTd)" should be 
implemented in a later version of Intel-VT (see PDF: 
ftp://download.intel.com/technology/computing/vptech/Intel(r)_VT_for_Direct_IO.pdf 
).
But actually I don't know the status of this technique too and if there 
are really advantages for the user right now!
