# MTLCounterResultStageUtilization

The data structure for storing the data you resolve from a stage-utilization counter set.

```
struct MTLCounterResultStageUtilization
```

## Overview

For steps that explain how to resolve data from a counter set, such as [`stageUtilization`](/documentation/Metal/MTLCommonCounterSet/stageUtilization), see [Converting a GPU’s counter data into a readable format](/documentation/Metal/converting-a-gpus-counter-data-into-a-readable-format).

## Topics

### Stage utilization values

[`totalCycles`](/documentation/Metal/MTLCounterResultStageUtilization/totalCycles)

The total number of cycles the GPU uses to run a pass.

[`vertexCycles`](/documentation/Metal/MTLCounterResultStageUtilization/vertexCycles)

The number of cycles the GPU uses to run vertex shaders during a pass.

[`tessellationCycles`](/documentation/Metal/MTLCounterResultStageUtilization/tessellationCycles)

The number of cycles the GPU uses to run the tessellation stage during a pass.

[`postTessellationVertexCycles`](/documentation/Metal/MTLCounterResultStageUtilization/postTessellationVertexCycles)

The number of cycles the GPU uses to run post-tessellation vertex shaders during a pass.

[`fragmentCycles`](/documentation/Metal/MTLCounterResultStageUtilization/fragmentCycles)

The number of cycles the GPU uses to run fragment shaders during a pass.

[`renderTargetCycles`](/documentation/Metal/MTLCounterResultStageUtilization/renderTargetCycles)

The number of cycles the GPU uses to write data to render targets during a render pass.

### Swift support

[`init()`](/documentation/Metal/MTLCounterResultStageUtilization/init())

Creates a default stage-utilization result.

[`init(totalCycles:vertexCycles:tessellationCycles:postTessellationVertexCycles:fragmentCycles:renderTargetCycles:)`](/documentation/Metal/MTLCounterResultStageUtilization/init(totalCycles:vertexCycles:tessellationCycles:postTessellationVertexCycles:fragmentCycles:renderTargetCycles:))

Creates a stage-utilization result from utilization values.
