Concern that your not-so-old, standard model PS4 is already redundant should be set aside with the release of the PlayStation 4 Pro since, at its heart, the new console remains a PS4. The Pro does, though, pack a good deal more power than a standard PS4, sporting 2.1GHz of central processing power and graphics processing that runs at 4.2 teraflops.The result is a machine optimised for 4K and HDR screens, as well as PlayStation VR. The idea is the bolstered power makes games thunder along with finesse on new display technologies that depart from the convention of 1080p HD resolution. It’s down to individual studios to decide how to harness the Pro’s power, so the difference the system makes varies from game to game. However, the new model does deliver a slightly more fluid VR experience, and there is a notable boon to the visual polish and movement of many non-VR games.Yet without upgrading to the new visual technology, Sony’s latest isn’t essential, but rather a powerful luxury item with great potential.
