P-states provide a way to scale the frequency and voltage at which the processor runs so as to reduce the power consumption of the CPU.
Only certain instance types on aws support P-states and/or C-states. See here for the list https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/processor_state_control.html
