Power Management Enhancements in the 45nm Intel® Core™ Microarchitecture

CONCLUSION

All the idle power improvement features introduced in the Penryn family of processors, namely DPD, CC3 in servers, Deeper Sleep in the desktop platform, and quad-core processors, met or exceeded the pre-silicon estimations. To the end user this means an increase in battery life on the mobile platforms, or a decrease in electricity usage in the desktop and server platforms. All these power improvements were achieved without any loss in functionality and negligible performance impact on real-world applications and benchmarks.

EDAT and Dual EDAT provide a means of efficiently utilizing the power envelope of multi-core platforms such that performance is not always constrained by the worst-case TDP scenario. This technology will be employed by this and the next-generation Intel processors.
