The Galaxy Note 20 Ultra has just a little better hardware performance than Galaxy A51, and although they both have a Octa-Core CPU, the Galaxy Note 20 Ultra also has 8 GB more RAM. Samsung Galaxy Note 20 Ultra captures much better pictures and videos than Samsung Galaxy A51, because it has a way larger camera sensor capturing much better quality pictures, a much higher 7680x4320 video resolution, a camera in the back with a way higher 108 mega pixels resolution and a larger camera aperture to capture better low-light photos and videos.
