Purpose Allows you to receive information about processor groups. Processor group information lists the existing processor groups while indicating the possible values of the performance parameter for each of them. This parameter is a combination of the matching frequency and voltage (Operating Performance Point, or OPP). The frequency is indicated in kiloherz (kHz) and the voltage is indicated in microvolts (µV). Parameters
