Ubuntu will run on just about any system. There's no need to compare versions, however the desktop might be the problem to keep in mind. If there's issues, right click on the Ubuntu Logo and select
Ubuntu 2D to use a less resource intensive desktop.
If issues still arise, pressing Ctrl+Alt+F1 will call up the console. Login and put in
tasksel and use the arrow keys to navigate around to find Ubuntu Desktop. Press space to uncheck it and select a different desktop that'll work for you. Examples are Lubuntu, Xubuntu, and so forth. Press enter when you are done to install the new desktop before rebooting.
Optionally, if the 2D Desktop is working as I suggested, you might want this as default for all users and future users, so opening a terminal by Ctrl+Alt+T and putting in
sudo /usr/lib/lightdm/lightdm-set-defaults -s ubuntu-2d
