Hi,
I have two problems:
- someone has 12 logic processors in Microsoft Windows task manager but someone has 20 logic processors for same i7-12700K? What is the reason of difference?
- How to identify p-core and e-core in Microsoft Windows task manager? I want to test the performance but I can't identify p-core and e-core, is there a tool I can use?

I can answer the first question. The Core i7-12700K processor has 8 pCores and 4 eCores. When Hyperthreading is enabled, you will have 16 threads from the pCores plus the 4 threads from the eCores for a total of 20 threads. When Hyperthreading is disabled, however, you will only have 8 threads from the pCores and thus a total of 12 threads.
As for the second question, since I don't have a 12th gen processor, I am not sure of the answer. Have you tried running AIDA64? If anyone has support for this, I believe it will be them.
Hope this helps,
...S

Hi,
I really appreciate your kindly and professional help. I use all 20 logic processors in scientific computing software, there are only 8 threads have high work load, theother 8 threads of pCore only have low work load in 600 seconds computer time.
OS: Windows 10 21H2;
Task manager
In AIDA64, I find the eCore cpu utilization

Hello 1nteldevteam,
Thank you for posting on the Intel® communities. I am sorry to know that you are having issues with your Intel® Core™ i7-12700K Processor.
In order to better assist you, please provide the following:
1. Run the Intel® System Support Utility (Intel® SSU) to gather more details about the system.
- Download the Intel® SSU and save the application on your computer: https://www.intel.com/content/www/us/en/download/18377/intel-system-support-utility-for-windows.html
- Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change it to "Detailed View".
- To save your scan, click Next and click Save.
2. Do you still see the mismatching with the logic processors?
