Advanced Micro Devices (AMD) has hired Raja Koduri, a former Apple graphics chip designer to bolster its engineering leadership bench as it turns itself around. Raja Koduri, who had previously served AMD before joining Apple,will be rejoining AMD four years after leaving that company.

Lisa Su, an AMD senior vice president, confirmed in an interview with the Walll Street Journal Friday that Koduri will be rejoining AMD's graphics team. In his new role, Koduri will have overall responsibility for driving AMD's innovation in visual and accelerated computing.

Koduri served as director of advanced technology development at ATI Technologies before AMD acquired the company. At the time he left AMD in April 2009, Koduri was serving as chief technology officer of AMD's graphics product group. He was most recently director of graphics architecture at Apple, where he spearheaded developing the performance, quality, programmability and power-saving features in the company's graphics processor roadmap. He left Apple in March.
