The Raw Global Illumination Render Element stores how much indirect lighting (reflected diffuse light) is received by surfaces in the scene. This raw element is useful for fine-tuning indirect lighting in the compositing process.

The Raw GI pass is untouched by the diffuse colors of the scene and represents the pure indirect lighting contribution. You can use this raw element to reconstitute the GI by multiplying Raw GI with the Diffuse.
