intel-compute-runtime package. The proprietary Intel OpenCL runtime, in
the intel-ocl package, is an alternative for Gen7 GPUs.

The intel-compute-runtime or intel-ocl package can be added to
[](#opt-hardware.graphics.extraPackages)
to enable OpenCL support. For example, for Gen8 and later GPUs, the following
configuration can be used:
Choose your runtime based on your Intel CPU/GPU generation:

- `intel-compute-runtime`: Since `Broadwell` 5th gen, open source, runs on GPU
- `intel-ocl`: Since `Ivy Bridge` 3rd gen, closed source, deprecated, runs on CPU
- `beignet`: Since `Ivy Bridge` 3rd gen, open source, deprecated, runs on GPU

i.e.

```nix
{
hardware.graphics.extraPackages = [
intel-compute-runtime
];
hardware.intel.opencl.runtime = "intel-compute-runtime";
}
```

I consider this option documentation, also it's the same amount of code to add stuff to extraPackages, this one makes it easier to discover what needs to be done to get opencl running on a given Intel CPU.
