The photonstophotos site is a good resource for seeing how your camera behaves if you like graphs. For hardcore Astrophotographers who need every bit of information it's a benefit.
It's more about the ideal high iso for your camera. Retards shot 100 iso and pushed it to over 9000 and got confused. Dual iso is now a thing.
It's not magic but is a thing. If your camera is "somewhat" iso invariance you have a little more room for post processing. Many Canon cameras are poor in this area, pushing only a couple of stops will degrade the image.
The Fujifilm x100 is a nice little iso invariance camera.
