Choose a processor to minimize the energy used by your workload

Workload characteristics impact the power effectiveness of a processor. Some workloads, such as data-intensive or compute-intensive tasks, may require more processing power to achieve a desired level of performance. In such cases, a more powerful processor with higher power consumption may be able to complete the workload faster, resulting in shorter overall runtime and potentially lower total energy consumption than a less powerful processor running the same workload for a longer duration.  If a workload is optimized for a particular processor architecture or has specific requirements that can be better met by a more powerful processor, then using that processor may result in lower energy consumption overall, despite its higher power consumption. Test with your expected workload to help narrow down a processor choice.
