PS4 SDK Update Unlocked 7th CPU Core For Gaming

Forums - Sony Discussion - PS4 SDK Update Unlocked 7th CPU Core For Gaming

It is just a waste of resources to lock cores or memory away at all. Dynamic resource allocation with priority for the consoles internal operating and encryption systems would be much more efficient and unlock all 8 cores for gaming. Only a very small fraction of the locked away resources are really needed, the rest is just not used and wasted.

That was my understanding as well. Xbox1 7th core is not fully unlocked, and on top of that the OS can still claim some more back when running some functions.

I guess we won't know for sure until official statements are released, but if it's the entire core the PS4 will have a slight advantage, especially as developers would be able to plan to fully utilise the core with no worry that it could suddenly drop performance.



Looks like Sony is copying MS again. What's next, backwords compatibility to PS2? :)

This will help with all multiplats that come out in 12+ months and exclusives that come out 6+ months from now. It's not like developers are redesigning games for this.

So, will help eventually.



It is near the end of the end....

No. 

so why they reserve it in the first place?


Because with PS4 Sony is continuing the same philosophy that was in force with its predecessors. It differs in detail, but overall it is the same intention. The idea is to prevent developers to be able to fully tap into the hardware from the very beginning, being in control of how much games will gradually improve over the consoles life cycle. However, with the PS4 devs have not that hard a time as with the PS3, which was plainly intentionally made hard to develop games for.

Hunting Season is done...

werent the xbox be able to go from 720 to 900p after they did similiar things? Maybe it will give a huge performance boost to realize 60fps for some games

doubt it, but might help some keep more steady 1080p 30fps.

That's the thing with consoles a few years in and they start to optimise the hardware... Efficiency, same hardware a little more juice!


Actually it's optimized software. ^^


Sorry my bad, optimized software for better hardware performance.

Nope. 720p to 900p was after freeing Kinects GPU reserves. That ate up to 20% of GPU performance AFAIR.

CPU time also was reserved for Kinect in the beginning. So MS' first step was reducing the system load Kinect had. Then they freed up resources from the seventh core, which might have been one reason a few games had better frame timing/less framerate drops on Xbox than on PS, the CPU already cloccks slightly higher. That usually was with games reaching 900p on One and 1080p on PS4, so no change on the graphics front here.

Right now we're likely getting to the point where all possible resources are freed for games. Both will need one core and plenty of RAM for multitasking, background stuff like snap functions etc., so some tweaks might still be done, but all the big steps are already made.

Doesn't mean they can't tweak their systems anymore though. Both will keep on working on their API's and so on.

Huh. Ms did this months ago if my memory serves me. Hopefully third party devs can now create games for the consoles with 7 cores in mind.


Not sure how much PS4 only having 6 cores impacted X1 version that could use 7 cores... but if it improve both versions and have more stable framerate I'm happy.

Maybe this update can allow some patches to popular games with framerate issues and improve it? Doubt many devs will use it, but those that have strong support and rely on DLC or sequels may intend to do it on good faith.
