  • High Performance Mode

  • Efficiency Mode(Default)

  • Maximum IO Performance Mode

  • Balanced Memory Performance Mode

  • Balanced Core Performance Mode

  • Balanced Core Memory Performance Mode

  • Auto

  • [Efficiency Mode]: Maximum performance per watt by opportunistically reducing frequency/power.

  • [High-Performance Mode]: Favor core performance more than IO die performance.

  • [Maximum IO Performance Mode]: Favor IO die performance more than core performance.

  • [Balanced Memory Performance Mode]: Inherits the advantages of the [High Performance Mode] under heavy load, while being more efficient at light load.

  • [Balanced Core Performance Mode]: Biases toward consistent core performance across varying core utilization levels by preventing active cores from using the power budget of inactive cores.

  • [Balanced Core Memory Performance Mode]: Combines the [Balanced Memory Performance Mode] and the [Balanced Core Performance Mode].

PCIe Power Brake
  • Reactive

  • Proactive (Default)

  • Disabled

PCIe Power Brake quickly reduces the power consumption and performance of high-powered PCIe devices. Performance of low-powered PCIe devices are not impacted by this setting. A high- powered PCIe device is the one that is rated at 75W TDP or higher.
