# ComputeShader

> Compute Shader asset.

## Definition

* **Type:** Class
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule
* **Inherits from:** [Object](/engine/6000.7/script-reference/unityengine/object.md)

```csharp
public sealed class ComputeShader : Object
```

## Remarks

Compute shaders are programs that run on the GPU outside of the normal rendering pipeline. They correspond to compute shader assets in the project (.compute files).

Compute shader support can be queried runtime using [SystemInfo.supportsComputeShaders](/engine/6000.7/script-reference/unityengine/systeminfo/supportscomputeshaders.md). See [Compute Shaders](/engine/6000.7/manual/materials-and-shaders/shaders/writing-custom/class-compute-shader.md) overview for more info about platforms supporting compute shaders.

### Operators

| Operator                                                                           | Description                                                             |
| ---------------------------------------------------------------------------------- | ----------------------------------------------------------------------- |
| [operator ==](/engine/6000.7/script-reference/unityengine/object/op-equality.md)   | Compares two object references to see if they refer to the same object. |
| [bool](/engine/6000.7/script-reference/unityengine/object/op-implicit.md)          | Determines whether the object exists.                                   |
| [operator !=](/engine/6000.7/script-reference/unityengine/object/op-inequality.md) | Compares if two objects refer to a different object.                    |
