1. An apparatus comprising: a multi-domain processor including a first domain and a second domain, each of the first and second domains to operate at an independent voltage and frequency, the multi-domain processor further including first logic to dynamically allocate a power budget for the multi-domain processor between the first and second domains at run time, wherein the first logic is to dynamically allocate substantially all of the power budget to the first domain for a first workload, and to dynamically allocate substantially all of the power budget to the second domain for a second workload executed after the first workload.
