May the function of ps4 go further?
In the past, many game developers mentioned that Sony only opened up six of the PS4's eight CPU cores to them, with the remaining two being used in PS4's operating system. Sony may have quietly upgraded the SDK (software development kit) recently to allow developers to use the seventh CPU core.
This update was discovered in the recent fmod (an audio engine) audio API update.

And that's very close to the description of the update when Microsoft unlocked the CPU core of the 7th Xbox One in January this year.

However, Sony has not officially announced this news at present, and the SDK itself is under a confidentiality agreement.
