IBM is considering a sale of its chip business, according to a report in the Financial Times. The article suggested that IBM may also look for a new partner with which it could spin off a joint venture, but either way it’s appointed Goldman Sachs to see if anyone’s interested. IBM’s semiconductor business is very cutting-edge, experimenting with new materials and technologies such as photonics, graphene and carbon nanotubes. Its Power architecture is also used in some IBM servers and supercomputers such as Watson. IBM said last month that it was selling its x86-architecture server business to Lenovo, the same company that took on its PC business in 2004.
