Abstract
In this paper, we study the space of chip multiproces-
sor (CMP) organizations. We compare the area and per-
formance trade-offs for CMP implementations to determine
how many processing cores future server CMPs should
have, whether the cores should have in-order or out-of-
order issue, and how big the per-processor on-chip caches
should be. We find that, contrary to some conventional
wisdom, out-of-order processing cores will maximize job
throughput on future CMPs. As technology shrinks, limited
off-chip bandwidth will begin to curtail the number of cores
that can be effective on a single die. Current projections
show that the transistor/signal pin ratio will increase by a
