In the rush to exascale computing, Intel is making a small change that could have a big impact on system design with its upcoming Xeon Phi chip. Intel on Tuesday promised big performance and power improvements with the redesigned chip, code-named Knights Landing, which analysts said could ship next year or 2015. The chip will also have interconnect and memory advances, Intel has said, that could separate it from other co-processors like graphics processors, which are widely used to accelerate technical computing.
