# isLowPower A Boolean value that indicates whether the GPU lowers its performance to conserve energy. ``` var isLowPower: Bool { get } ``` ## Discussion Some systems contain multiple GPUs that run with different performance and energy characteristics. At runtime, choose a GPU that best matches your performance needs while considering the current state of the system. For example, your app may choose a lower-power GPU if it doesn’t need the best possible performance on a MacBook Pro that’s running on battery power. For more information on discovering and selecting GPUs at runtime, see [Multi-GPU systems](/documentation/Metal/multi-gpu-systems). > Note: > Systems with Apple silicon only have one GPU, which removes the need to choose a GPU. The property is typically for integrated GPUs and for discrete GPUs. However, an Apple silicon GPU on a Mac sets the property to because it doesn’t need to lower its performance to conserve energy. --- Copyright © 2026 Apple Inc.
