PS4 or PS4 Pro: what really is the difference? If you're looking to get a new Playstation 4, or looking for an upgrade, you may well be deliberating over the best choice out of these two, admittedly-similar consoles. But while both may play the same library of games, there are a fair few differences under the hood, and many gamers will want the highest-performing machine they can find for playing AAA games like God of War or sampling the best of Playstation VR.

The PS4 Pro is the premium console offering from Sony, but don't mistake it for a PS5: it's more a refit than a whole other machine. However, there's still a lot more going on with the new console than you might think.
