Power analysis of Woodcrest and Dempsey online

Article: Performance Per Watt: Dempsey and Woodcrest

Since the launch of Woodcrest, earlier this year, Intel has been back on the offensive, with higher performance and improved performance/watt. However, the performance/watt advantages have largely been unmeasured, up until now. In this review, Real World Tech compares the power efficiency of two generations of Intel's dual processor server platform: Dempsey versus Woodcrest. On average they found that using Woodcrest processors to replace Dempsey was roughly twice as power efficient, and typically reduced power draw by around 130 watts for a modestly configured system...quite a coup for a microarchitectural change without a process shrink.

Take a look here for more details, including complete power profiles with 1s sampling rates:
