If you compare the so-called “Next gen” Consoles graphics to an equivalent GPU on the PC, PS4 is roughly equivalent to a downclocked AMD 7850 GPU and Xbox1 is roughly equivalent to a downclocked 7770 GPU. The difference between these two cards is night and day. And so is the PS4 and Xbox one difference.
1080p/60fps – How consoles achieving it?
Consoles are achieving the 1080p/60fps standard by optimizing the games. Console games are heavily optimized. This custom optimization by developers allows them to run games at 1080p/60fps as standard. On the contrary PC games are being poorly optimized and instead, developers give all the options / Settings to them. So those with monster PC and those with low spec PC can play the game. The low spec PC users can tune down graphical settings and run them 1080p/60fps. Those with monster GPU run games in insane graphics everything maxed out.
