He's managed to destroy shareholder value, riding the share price down from the 8s to the 2s, brought AMD down to the lowest market share it has had in a decade, presided over a major flop, the APU, which includes mushrooming inventories and a write down, lost Apple's business, was forced to pay hundreds of millions to GF NOT to have to buy chips, burned up more than half of AMD's free cash, oversaw firing of 30% of AMD's workforce, and managed to achieve an all-time low share price.
Quite a list of accomplishments. Seriously, though, this guy is so bad that the Board has him muzzled now. The dufus was yacking about it into an open mic at an analyst conference. When the Board steps in an regulates when and how the CEO speaks, you can be sure that he is a CEO on the way out for incompetence.
He's currently #7 on the list of the 10 least valuable public company CEOs.
