Branching

Some people feel branching is too slow, even for modern gpus, if so and you really want to optimize you can always change the branching to something like

bool ring = isRing(i.worldPos, _RingPositions[index], _RingRadii[index]);
o.Albedo = lerp(o.Albedo, RingColor, ring);
o.Emission = lerp(o.Emission, RingColor, ring);
