(When) Will CMPs Hit the Power Wall?

Currently the power wall is one of the major obstacles chip industry is facing. At the same time processor architecture shifts towards chip multiprocessors (CMPs), which are believed to alleviate the power problem. In this paper we analyze the impact of the power wall on CMP design. As a case study we model a CMP consisting of Alpha 21264 cores, scaled to future technology nodes according to th...
