Abstract: Methods, systems, and apparatus for dynamic service level objective power control in a datacenter. In one aspect, a method includes determining a current service level value that measures a current performance of the service by a set of processing devices performing the service, the service having an associated service level objective value; and for each processing device: when the current service level value does not meet the service level objective value of the service, generating a first control signal that causes a processing device performing the service to operate at a first power consumption level; and when the current service level value does meet the service level objective value of the service, generating a control signal that cause the processing device to operate at a reduced power consumption level that is less than the first power consumption level.
