Enumeration Case

MTLStorageMode.private

The resource can be accessed only by the GPU.

Declaration

case `private` = 2

Discussion

Resource coherency between the CPU and GPU is not necessary because the CPU can’t access the contents of the resource. Metal may apply additional optimizations to private resources that are not allowed on shared or managed resources.

For more guidance on how to choose storage modes, see Setting Resource Storage Modes.

case shared

The resource is stored in system memory and is accessible to both the CPU and the GPU.

case managed

The CPU and GPU may maintain separate copies of the resource, and any changes must be explicitly synchronized.

case memoryless

The resource’s contents can be accessed only by the GPU and only exist temporarily during a render pass.
