The cost can shrink down if we only supersample the coverage information and change the opacity of the sampled point based on the coverage percentage, instead of supersampling both the coverage information and triangle's shading information. This is known as MSAA.
Or the cost can be spread into different frames, e.g. temporal antialiasing.

To add on, there is another anti-aliasing technique called temporal anti-aliasing. Because supersampling is memory intensive, TAA is used to approximate supersampling. It uses temporal filtering methods to improve stability in motion. (Feel free to correct me if I have any mistakes.)

What are smarter ways that we can resolve anti-aliasing outside of supersampling ?
