Power Management in Intel® Architecture Servers

Intel® Architecture Servers White Paper Intel® Architecture Servers During the last decade, Intel has added several new technologies that enable users to improve the power efficiency of Intel® architecture based platforms. Because these technologies have been introduced in different generations of microprocessors and chipsets over several years, it may not be apparent how they work together and impact the performance of higher-level applications. This paper explains each power-related technology and how they interplay in an Intel architecture-based platform. We present data showing how users can reduce the power consumed by a system when applications don’t need full processing power and also how the system can deliver higher performance with a power boost during periods of high loads. Understanding these silicon-level technologies will enable application developers, IT managers, and system users to harness Intel architecture’s full potential to deliver energy-efficient performance.
