<m> Buys </m> in Advanced Micro Devices announced Wednesday it is buying low - power server vendor SeaMicro, a surprise move that puts AMD in the systems business and disrupts Intel by acquiring one of its close partners. AMD will pay US$334 million in cash and stock for SeaMicro, an 80 - employee Silicon Valley startup that has gained attention for building highly dense and power - efficient servers for use in large - scale cloud computing environments. AMD plans to sell SeaMicro branded servers directly to customers, but it bought the company primarily for its technology, which it hopes to license to other server vendors to build their own low - power systems.
