C-State Selection – the available C-States are shown as different columns. The available C-states are numbered consecutively without gaps (C2, in this case, corresponds to Intel’s C6 deep C-state). Each row shows the percentage of time the logical CPU votes to stay in that particular C-State

P-State Selection – the screenshot shows 16 different P-States P0 to P7 P0 has the highest clock frequency (1.501 GHz) and P7 has the lowest clock frequency (0.80 GHz). Each logical core on the physical core can vote for a particular P-State (frequency) but the P-State assignment happens at the physical core level. Thus the lower P-State vote between the two requests is selected. On the other hand if a processor has a socket-level P-State granularity, then the chosen operating P-State would be the lowest vote across all cores on the socket

%Aperf/Mperf – this column shows the ratio of Aperf to Mperf which indicates the actual frequency at which the core is running. A value of 100 means the core is running at nominal/base frequency anything higher indicates running in turbo and anything lower suggests the core is running at lower frequencies. Note that the %Aperf/Mperf counter is updated only when the core is in the running state (C0-state) so the counter value is not valid when the core spends time in C1 or C2 idle sleep states
