I've been told this more than a few times and read it in various places.

processors that lets us bypass the x86 code emulation/translation and 
run "directly on the metal" (if there were such a thing).

The purpose, of course, would be to gain performance. Certainly this 
would already have been done if there was any significant gain to be
