Both of these devices use Android OS (Operating System), but Galaxy A51 has the newer 11 version and Xperia Z5 has Android 5.1. Galaxy A51 is a newer cellphone than Xperia Z5, but it's just a little thicker and somewhat heavier.
The Xperia Z5 features a bit better processing unit than Galaxy A51, because although it has less RAM, and they both have a Octa-Core CPU, the Xperia Z5 also counts with a graphics co-processor. Xperia Z5 has a better screen than Samsung Galaxy A51, because although it has a quite lower resolution of 1920 x 1080 and a lot smaller screen, it also counts with a bit greater pixels density.
Galaxy A51 has a bit better camera than Xperia Z5, because although it has a tinier diafragm aperture which is not favorable for low light captures and video, and they both have the same 3840x2160 (4K) video definition and the same video frame rate, the Galaxy A51 also counts with a back-facing camera with a way higher resolution and a bigger sensor taking more light and vivid colors.
The Samsung Galaxy A51 counts with a much greater memory capacity to install applications and games or saving photos and videos than Sony Xperia Z5, because it has a SD card slot that admits a maximum of 512 GB and 128 GB internal memory capacity.
