Peak power determination for an integrated circuit device

A circuit comprising peak power setting circuitry to set a peak power value for an integrated circuit device, the integrated circuit device having throttling circuitry to assert a power reducing feature of the integrated circuit device in response to a throttling signal assertion, the peak power setting circuitry including:

• a power supply interface to receive a value to estimate a peak power capacity of a power supply serving the integrated circuit device;
• processing circuitry to:
• determine an approximate peak power for the integrated circuit device using the estimated peak power capacity of the power supply;
• and
• determine a peak power for the integrated circuit device by increasing the approximate peak power for the integrated circuit device depending on an amount by which the integrated circuit device power is reduced in response to assertion of the throttling signal.

At least one non-transitory machine-readable medium having instructions stored thereon that, when executed, cause processing hardware to:

• receive at least one value to estimate a peak power capacity of a power supply serving an integrated circuit device;
• determining an approximate peak power for the integrated circuit device based on the estimated peak power capacity of the power supply;
• and
• determine a peak power for the integrated circuit device by increasing the approximate peak power for the integrated circuit device according to a peak power enhancement function, wherein the peak power enhancement function depends on an amount by which the integrated circuit device power is reduced by the integrated circuit device in response to assertion of a throttling signal.
