Hi, Martin!Exactly! Moreover to read the actual multi the core needs to wake-up, which introduces the observer effect.
May I ask you: how an "effective clock" looks programmatically? I just started to dig it for my project, and I use MSR to get values.
In my case, the results are slightly different than what HWInfo shows as an effective clock despite I tried to reproduce the logic as accurately as possible based on your explanation.
If it's not a secret (it's totally understandable if it is), can you PM me a snippet, pseudo, or some sort of formula?
Thank you in advance!
I have a Ryzen 2700X and when I expand the Core Effective Clocks tab I noticed that all 8 cores have a T0 and a T1 Effective Clock. After reading through this entire thread and creating an account it dawned on me that I might be seeing the physical and SMT threads. Is this correct?
