Advanced Micro Devices Inc. (NYSE: AMD), the maker of chips for PCs and servers, lost its chief technology officer yesterday. At a hardware company, it could be argued that the CTO is as important, if not more important, than the CEO. AMD recently announced another round of lay-offs, this time cutting 10% of its workforce. The firm also said its Q1 numbers would be disappointing.

According to The Wall Street Journal (subscription required), Phil Hester "has been closely associated with an AMD strategy known as 'accelerated computing,' which envisions the use of special-purpose circuitry being used on chips along with general-purpose microprocessors." To put it another way, he is one of the masterminds behind AMD's plans to compete with larger rival Intel Corp. (NASDAQ: INTC).

Each piece of news out of AMD makes the company look more like a restructuring candidate. It is hard to see why Hester would leave if he thought things were turning around. AMD has more than $5 billion of debt, most of it from buying graphics chip company ATI. The company's shares traded near their 52-week low. The firm's new forecasts may indicate that AMD will have trouble generating sufficient cash flow to service its debt.

Did someone mention Chapter 11?
