Am I doing something wrong?

The aov_write shaders are not supported on the GPU currently. You'll find the list of supported/unsupported nodes here. Unsupported shaders are also marked with an asterix in the shader tree on the left in the node editor.

You can use a passthrough shader to keep the main shading and only skip the aov write part on the GPU, like this:
