Power Consumption Measurements
Since AMD's SOI process is already excellent when it comes to low leakage and low idle power requirements, the improvements from 90 nm to 65 nm were not significant. We found a two Watt potential savings in idle power when moving to the latest versions.
The power consumption measurements under load revealed a significant fact: The first 90-nm Windsor core using the F2 core requires clearly more power than any other stepping. It's also clear that the 65-nm process isn't more efficient at high loads.
