Abstract: The ever-growing demand for computational power and high performance has led to a rapid growth in the semiconductor industry. This evolution has seen a continuous increase in CPU performance and the number of transistors on a chip has roughly doubled every two years – proving Moore's law. An inevitable consequence when achieving this is that more functional units, deeper pipelining and larger cache sizes have had to be implemented on the CPU chip. The result is a significant increase in the power consumption. Achieving high performance with low power consumption has been the traditional goal in high-end processors. In order to accomplish high performance, multithreaded and multicore CPUs have become the recent trend in semi-conductor technology. The purpose of this paper is to statistically analyse various factors that affect power, to study their relationship, and to quantify their influence on power consumption in multithreaded and multicore CPUs. The paper!
also discusses recent advancements in power savings through the implementation of power-limiting micro-architectural features (e.g. out-of-order execution, branch prediction, caching and prefetching) in contemporary multi-core processors, such as Intel Nehalem and AMD's Istanbul processors.
Keywords: power consumption, statistical analysis, power-limiting factors
