Sony unlocks the PS4's 7th processing core for developers

  

Ever since launch the PS4 has had a significant lead in graphical performance over the Xbox One, forever branding the PS4 as the "more powerful" console, allowing developers to run the PS4 versions of a game at a higher framerate or resolution than the Xbox One's version of the game. 

At launch both consoles were able to use 6 out of the consoles 8 CPU cores in games, but last year Microsoft opened up more of the Xbox One's performance, giving developers use of the consoles 7th CPU core and more GPU bandwidth in order to give developers more performance to use in their games, which has certainly help developers bridge the performance gap between the PS4 and the Xbox One.  

This boost in the Xbox One's performance came at a cost, as developers which used this extra performance would not be able to use the Kinect with their game or Xbox One Voice commands, as this performance was gained by disabling these features. 

Sony unlocks the PS4's 7th processing core for developers  

Now Sony has quietly launched a software developer kit which enables access to the PS4's 7th CPU core, allowing developers to access more CPU performance by utilizing this extra CPU core. Right now we do not know how games using the 7th CPU core will affect the PS4's features, similar to how the Xbox lost support for the voice commands and the Kinect.  

This update will not immediately give the PS4 more performance in-game, as developers will need to code their games with this extra performance in mind, but it does mean that developers will be able to make more demanding games, or use this performance it make their titles run more smoothly. 

Sony's PS4 already had a performance lead over the Xbox one, but with the developers now having access to more of the PS4's hidden potential the gap between PS4 and Xbox One games may increase further.

To me this just screams companies deliberately crippling performance from the start. By adding performance available to devs at a later date than launch seems like it was always kept in reserve for its mid life reawakening. Unfortunately with the resurgence of PC becoming a major gaming platform it seems they have been forced to eek out every extra bit of performance they can find.Quote

In the case of the Xbox One it was so that all games would be able to use voice commands and the Kinect. That was abandoned after Sony's advantage became clear.

I don't know what sony used the 7th core for before now, so some feature might be unused now or Sony has just made the OS require less CPU grunt through optimization or just making it run slower in games.Quote

I'm on the beta software list for the Ps4 and there's been lots of optimisation updates of late.

Maybe the dedicated core was for their porn camera..umm i mean playstation camera lol.Quote

Not really. SDKs are constantly being refined and improved for any software and this is just a case of Sony's Engineers doing just that. You can't blame them tbh. They aren't kings of software(not literally before some takes it that way) like MS engineers are and MS was kinda forced into doing it. Sony didn't really have a need for it. Just doing it now gives more people a reason to PS than Xbox.

Ya I want to know what unlocking it means they gave up on. They probably just unlocked it and gave devs the choice through the SDK to either use it for themselves or support PS Eye(or whatever its called now). I know the PS has a separate internet chip that handles that side of things so not much else it could be outside the OS.Quote
