Abstract: An apparatus and method to control temperature ramp rates including temperature spike detection and control. For example, one embodiment of a processor comprises: a plurality of cores to execute instructions; a power management unit to control power consumption of each core of the plurality of cores, the power management unit comprising: a frequency ramp governor or power step governor to determine a frequency ramp rate limit or power step limit for a core of the plurality of cores based, at least in part, on a present frequency or present power metrics of the core; a frequency limiter or voltage limiter to determine a maximum frequency or maximum voltage of the core based, at least in part, on a measured temperature; and limit resolution circuitry to determine a first frequency or a first power level of the core in accordance with the frequency ramp rate limit or the power step limit and the maximum frequency or maximum voltage.
