The PlayStation 4 and Xbox One contain a total of eight CPU cores but developers have access to only 6 cores for gaming. Xbox One team at Microsoft had unlocked the 7th CPU core [shared between game and some OS services] and added a slight overclock, which provided some wins against the PlayStation 4 in heavy CPU-processing scenarios. And it looks like Sony might have followed suit and unlocked the 7th core in their console as well. This is due to an update in the changelogs of the FMOD Audio API, which is a popular audio gaming middleware.
