You can use High-Power Mode on 14-inch MacBook Pro models with M3 Max and 16-inch MacBook Pro models with M1, M2 or M3 Max.
By default, your Mac is set to Automatic mode to balance energy use and performance. Low Power Mode reduces energy use to increase battery life. High Power Mode allows the fans to run at higher speeds. The additional cooling capacity may allow the system to deliver higher performance in very intensive workloads.
High Power Mode can improve performance in graphics-intensive workflows such as color grading 8K ProRes 4444 and 8K DNxHR video. In video editing and 3D applications, you may experience smoother playback and faster exports in High Power Mode.
In High Power Mode, the fan may run at a higher speed and you may hear additional fan noise. High Power Mode can be used whether your Mac is connected to power or not.
