Optimizing a server for power consumption and speed may require knowing what state the CPU is in and for how long. Using turbostat you can view the processor state information, including which state the CPU is in and how much time it's spending in that state. It's granular enough that you can tell per core what state the CPU is in as well as the entire CPU package combined. You can also see the electricity usage of the entire CPU as well as the cores and the graphics portions individually.
