AMD announced Tuesday that long-time chief sales officer and senior vice president Emilio Ghilardi was leaving the company.

The announcement comes after a series of changes at the top and an unparalleled management reshuffle at AMD over the past several quarters. AMD CEO Rory Read will take over Ghilardi’s responsibilities and serve as interim sales chief until a replacement is found.

No reason for Ghilardi’s departure was given and his resignation is effective immediately.

Update:

Ghilardi was apparently let go and he did not leave the company to "pursue new opportunities" as AMD claims. John Byrne, Corporate Vice President Sales Americas Mega Region and Darren Grasby, Corporate Vice President Sales will assist Read in the interim. Both are ex-ATI chaps and they are among the few former ATI execs who are still part of AMD's top management.
