# isLowPower

A Boolean value that indicates whether the GPU lowers its performance to conserve energy.

## Declaration

```swift
var isLowPower: Bool { get }
```

## Mentioned in

Finding multiple GPUs on an Intel-based Mac

## Discussion

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. note: Systems with Apple silicon only have one GPU, which removes the need to choose a GPU. The property is typically true for integrated GPUs and false for discrete GPUs. However, an Apple silicon GPU on a Mac sets the property to false because it doesn’t need to lower its performance to conserve energy.
