# Memory heaps

Take control of your app’s GPU memory management by creating a large memory allocation for various buffers, textures, and other resources.

## Overview

Overview Use an MTLHeap to quickly create and destroy GPU resources. Heaps can also help your apps save memory by aliasing portions of it in multiple places. Create a heap by calling an MTLDevice instance’s makeHeap(descriptor:) method. note: Metal only synchronizes resources that you create from a Metal heap and that have the hazardTrackingMode property set to MTLHazardTrackingMode.tracked.
