First of all, thank you for your reply. The Datasheet does not solve my problem precisely, since I need the Voltage and Current values that match each frequency configuration in order to calculate the power. Do you have any further recommendations on how I can ready the state (voltage and frequency) of my machine for the different frequencies, or is there any datasheet involving such values?
I am with Intel Customer Support and I am trying to locate this information for you or address your request in the correct direction but I cannot promise anything as this maybe under restricted access.
Could you provide me with more details? Is this a business or an individual project? How many systems are involved? What is the purpose of the project?
You can send me a private message or you can call our Support Center and create a Service Ticket if you don’t want this information to be disclosed in this forum.
Please accept my apologies for the delay in getting back to you with a response, as I mentioned before I work for Intel Customer Support so I took the detailed information that you sent me on a Private Message to justify this request and I went up to the engineering level and the answer I got from them is that the information that you are requesting is Intel Confidential and it cannot be shared with customers.
Based on that, I wont be able to help you with this request but please let me know if there is anything I can help you with.
Dear Intel community,
I have a similar issue with identifying the voltages that correspond to the P-states of my processor (Xeon 3470). Given the similarity, I believe my question is quite in-line with the current thread.
As I have read in Intel documentation  the p-states are actually pairs of frequencies and voltages, rather than a sole frequency value (per state). However, the DVFS driver of my system (Ubuntu OS with acpi-cpufreq driver for DVFS) is not exposing voltage information per core and per state. In that sense, I would like to check whether the available frequency-voltage pairs can be derived from any Intel documentation.
Given that I would like to have a valid power metric for my work, it is important that I have access to *both* frequency and *voltage* of each core's p-state.
I would like to thank you for your time.
