Chipmaker Advanced Micro Devices will take a $948 million charge for Q2, the company announced this morning. Much like last year, the bulk of the writedown is due to the declining value of the company's ATI acquisition, for which it paid $5.4 billion in 2006. The resulting lines of cellphone graphics chips and digital TV chips just haven't sold as well as expected. The company's quad-core mobile graphics chip, codenamed Eagle, won't arrive to save the day until 2010. More important to some of us: A $32 million charge for employee severance packages.
