Sony’s PS4 has an 8-core CPU, but only 6 of those cores are available for games. Now a new update to the SDK for developers has reportedly unlocked the 7th core to be used for games, while the 8th core will be reserved for system operation and the OS.
It’s a similar story with the Xbox One: 8 cores, but only 6 for games. However, Microsoft changed that earlier this year, as they unlocked the 7th core for game developers (while the 7th core also runs some system operations as well).
This allowed the Xbox One to be a bit better when it comes to CPU power.
Not to be overtaken, Sony has now reportedly unlocked the 7th core for developers to use in games. The PS4 already has a much more powerful GPU than the Xbox One, and this new addition will keep the console as the most powerful one.
The evidence comes from FMOD, an audio middleware supplier, whose recent documentations reveal that the PS4 has 7 cores available instead of 6.
This is what the recent update changelog had to say (our emphasis in bold):
Firelight Technologies FMOD Studio API
Detailed Revision History

LowLevel API – PS4 – Added FMOD_THREAD_CORE6 to allow access to the newly unlocked 7th core.
This isn’t official by any means, as Sony hasn’t made any announcements. Microsoft proudly announced their upgraded Xbox One hardware, and we’re sure that Sony will do the same very soon.
If it’s true.
