Or they may use some of the new 'cooperative' power management techniques that Microsoft has developed in partnership with hardware manufacturers.įor more info on cooperative power management techniques, see the section named Collaborative Processor Performance Control in the Advanced Configuration and Power Interface Specification. Also, newer generations of processors are generally more energy efficient, and they may expose more power states for the Windows power management algorithms, which enables better power management at all levels of performance. In general, opt for the lowest TDP processor that will meet your performance goals. Processors have a thermal design point (TDP) rating that gives a basic indication of energy consumption relative to other models.

Processor Recommendationsįrequency, operating voltage, cache size, and process technology affect the energy consumption of processors. The following sections lists guidelines for power characteristics and capabilities of server hardware components. High performance and low-energy usage are often conflicting goals, but by carefully selecting server components, you can achieve the correct balance between them. It is important to recognize the increasing importance of energy efficiency in enterprise and data center environments.
