QuantLib benchmark with settings of Configuration: Single-Threaded. Balanced - Default was the fastest.

QuantLib benchmark with settings of Configuration: Multi-Threaded. Performance was the fastest.

The QuantLib benchmark in both single and multi-threaded modes show how the single-threaded workloads tend to have the greatest benefit from power-savings with the EPP value.

OpenVINO benchmark with settings of Model: Vehicle Detection FP16, Device: CPU. Performance was the fastest.

OpenVINO benchmark with settings of Model: Face Detection Retail FP16-INT8, Device: CPU. Performance was the fastest.

OpenVINO benchmark with settings of Model: Face Detection Retail FP16-INT8, Device: CPU. Balanced - Default was the fastest.

The OpenVINO AI benchmark was consuming around ~9 Watts less while running various benchmarks in the EPP power-saver mode with only a small hit to the performance.

Ngspice benchmark with settings of Circuit: C7552. Performance was the fastest.

Ngspice benchmark with settings of Circuit: C2670. Performance was the fastest.

GNU Octave Benchmark benchmark with settings of . Performance was the fastest.

The performance EPP setting helped boost the Intel Meteor Lake performance in a number of the benchmarks but the most significant difference tended to be with the EPP power-saver setting for extending your laptop's battery life and reducing cooling needs.
