Product GM Rick Bergman out at AMD

Things are changing over at chip giant AMD: while it has finally found itself a new chief executive in the form of ex-Lenovoer Rory Read, it's just lost Rick Bergman.

Bergman, previously of ATI before the graphics specialist's acquisition by AMD in 2006, was promoted to the role of general manager of the product group in 2009 and is generally believed to have helped push the company forward in recent years.

Officially, Bergman's departure is a voluntary resignation, but coming so soon after the appointment of a chief executive officer at the company it would appear that there has been something of a conflict of personalities at the chip maker.

"I want to thank Rick for his many contributions to AMD and wish him well in his future endeavors," fresh, new AMD boss Read claimed in a statement, without going into detail as to what those endeavours might included.

Currently, it's not known what Bergman plans to do next. With his years of experience of the graphics market, a move to Nvidia wouldn't be impossible - but to ditch years of red-vs-green rivalry would be a challenge, and Nvidia president Jen-Hsun Huang is vocal about his plans to move his company towards mobile SoCs rather than discrete graphics.

At the same time as Bergman's resignation was announced, Read confirmed that Paul Struhsaker - formerly of US communications giant Comcast - has been picked up by the company to act as corporate vice president and general manager of the newly-formed commercial business division.

Struhsaker brings with him an interesting list of talents: with over 27 years of experience in ASIC and FPGA development, his hiring - taken in conjunction with the formation of the division which he will lead - could indicate that AMD is looking to do a bit of diversification into the lucrative communications chipset market.
