Hi, SujitPandey, Thank you very much for joining the Intel® Processors communities.
In regard to that link, remember that is a 3rd party link, the information in there is not officially validated by Intel, so we cannot confirm it is correct. Besides that it is also related to AMD and there is no information in our documents about those processors. The processor’s information we support is strictly for Intel units.
I can see on that link, that the processor showing is the Intel® Xeon® Processor E5-2699A v4, on the link below you will be able to confirm that it supports a dual socket configuration, please check “Max CPU Configuration”:
If the processor supports Hyper-Threading Technology and it has 64 cores, then the operating system will see 64 physical cores and 128 logical cores. The Intel® Xeon® Processor E5-2699A v4 has 22 cores, so if you use 2 of them, the you will have 44 cores, but the operating system will detect 88 cores as shown in the picture, so you are right in assuming that if the total cores is 64 then the maximum number of threads that can execute is 128.
In regard to your question about how the frequency works it and the knowledgebase article, the following link is for the technical product specification for that processor’s family, in there you will find additional details about how the processor works, normally the frequency is shared between the cores that are active, so depending on the work load and tasks the processor is handling, the active cores can be just 1 or 2, and based on that is how the frequency will be shared:
Any further questions, please let me know.
