    Determinism Slider = Performance | Power
    Power and Perform determinism mode (System management Unit (SMU) policy choices. The effective GHz each core will run at is under the control of the SMU. This tracks power, current draw and temperatures across all parts of the processor and has knowledge of the cTDP power budget.

    ‘Performance’: reduces CPU to CPU performance variability within a cluster. Provides repeatable performance for identical SKUs across your cluster by using a lowest baseline reference setting common to all CPUs within that SKU range.

    ‘Power’: takes advantage of yield variability and will provide improved runtime performance and guarantees the power draw of each part will be up to but not exceed the cTDP power limit. If you wish to set the cTDP to its maximum value, then you must set ‘Determinism Slider=Power’
