AMD RAPL power domains relations
Intel CPUs provide power monitoring via RAPL for several power domains - PKG, DRAM, PPx, Platform. Many sources describe these power domains and their relations, nice figure is in Khan, K. et al. “RAPL in Action.” ACM Transactions on Modeling and Performance Evaluation of Computing Systems (TOMPECS) 3 (2018): 1 - 26.
AMD CPUs also have RAPL interface for power monitoring (as far as I know) PKG and Core domains, however I have not found any source presenting relations of these power domains. Does PKG domain include Core domains? One would expect that it does, but it is just an assumption.
"PKG domain includes of cores and also IO die and other in socket components."
