In the above Dr Dobb's article from a little over a year ago, AMD Senior
Fellow Leendert vanDoorn states "the Advanced Encryption Standard (AES)
algorithm gets a factor of 5 performance improvement by using the new
SSE5 extension". However, glancing through the SSE5 specification, I
can't see at all how such a dramatic speedup might be achieved. Does
anyone know any more, or can anyone see more than I can in the spec?
