It seems the PlayStation 4 is now just a little more powerful than before. At least for game developers, anyway. None of the console's components have changed -- instead it's being reported that a seventh core has been "unlocked" in the CPU. Until now, six of the PlayStation 4's eight-core CPU have been dedicated to games, while the remaining two handle the operating system. In all likelihood, this was a conservative setup to ensure consoles ran smoothly at launch. It also gave Sony some wiggle-room if they needed to make any system changes or optimizations. Now, however, it seems the company is happy with the console's performance and willing to give developers a tad extra power.
