I see no difference

I am using a pretty good gaming laptop and Blender 3.3, so maybe the hardware or the software has made the portal obsolete?

    The difference can be subtle. Try making two renders, one without the light portals and one with them, then cycle back between the two and see if you can spot the noise reduction.

    It depends highly on the scene, but here's a comparison with and without Light Portals and Path Guiding (CPU only at the moment, Blender 3.4+):

    All done with 64 Samples, no Denoising.
