# cpuCacheMode

The CPU cache behavior for any resources you allocate from the heaps you create with this descriptor.

## Declaration

```swift
var cpuCacheMode: MTLCPUCacheMode { get set }
```

## Discussion

Discussion This property’s default value is MTLCPUCacheMode.defaultCache. The resources you allocate from a heap inherit that heap’s CPU cache mode.
