Intel Xeon processors P-States

I am a research student and I would like to know the supported P-States (voltage/frequency tuples) for the following Intel Xeon processors:

1. Intel Xeon Platinum 8180

2. Intel Xeon E7-8855 v4

3. Intel Xeon E5-4640 v4

4. Intel Xeon E3-1240 v6

I have checked each processor's datasheet and manual without any luck.

I have searched this forum (as well as other web resources) but again, I could not find any specific information about the supported P-States (along with the corresponding voltage and frequency per P-State) of the above processors.

Where can I find the above information?

Is there anyone that can provide me with that information?

Dear David,

I would greatly appreciate it if you could provide me the requested information.

Furthermore, if it is possible, I would like to know whether all of the above processors support per-core DVFS (Enhanced Intel SpeedStep Technology).

Many thanks in advance.

Hello gs406,

 

 

Thank you for patiently waiting,

 

 

I apologize for the really long delay, the information that I have been able to find is the following:

 

1. Intel Xeon E7-8855 v4

https://www.intel.com/content/www/us/en/processors/xeon/xeon-e7-8800-4800-2800-families-vol-1-datash... https://www.intel.com/content/www/us/en/processors/xeon/xeon-e7-8800-4800-2800-families-vol-1-datash...

2. Intel Xeon E5-4640 v4

If you needed specific information about those devices then my recommendation is for you to get in contact with our Intel ® Developer's Zone, they would be able to provide you with any specific information you may need. Please refer to the link below:

 

 

https://software.intel.com/en-us/support Intel ® Developer's Zone.

 

 

You could try to register in the community part of that support and then the information should be responded there.

 

 

I apologize for any inconvenience.
