Sony unlocks PS4’s 7th CPU core for developers

Sony has gone ahead and unlocked more of the PS4's power for developers, by giving them the opportunity to make use of the console's 7th CPU core. This change came in the latest SDK for the console and may help Sony keep its performance lead on Microsoft's Xbox One, which also had an additional core unlocked last year after the Kinect was unbundled from the console.

Up until now, the PlayStation 4 has had two of its eight cores reserved for the operating system, so developers are limited to six cores while optimizing games. When the Xbox One had its seventh core unlocked, it allowed more games to match the PS4's resolution and frame rate. However, with Sony following suit with the same thing, we may see the gap between the two consoles widen again.

The information came about on Friday night via the Beyond3D forum, which showed changelog notes for the PlayStation SDK, one of the entries reads: “PS4 – Added FMOD_THREAD_CORE6 to allow access to the newly unlocked 7th core”. Since then, Eurogamer also managed to speak to a source of its own which confirmed this information to be true.

There are a few things to keep in mind though. While developers may have access to the 7th core, older titles won't make use of it unless specifically patched to do so. On top of that, much like we saw with the Xbox One, this additional core will share resources with the OS, meaning that the amount of processing power available at any given time could vary.

KitGuru Says: Right now, the PS4 seems to be largely limited to 1080p, 30 frames per second gaming. With access to more CPU power, we may see future games on the PS4 run better, though we won't know by just how much until newer games start coming around.

  1. Doubt it’s gonna matter that much. It’s not like that extra core is going to mean an upgrade to 60FPS or something. It’s a nice extra for developers, but not one that the average gamer is going to notice immediately.

  3. don’t think it actually made much difference for the xbone, doubt it will do much for the ps4.

  5. In the grand scheme of things, the PS4 is still a console and will never even come close to the performance of a mediocre PC.

  7. Ya, let’s build a $299 PC to compare. Go ahead with the OS too. And a 2015 $2000 PC will never provide the enjoyable experience of sports games, fighting games, etc. in a co-op environment with your friends over beers, nor will it allow one to play Bloodborne, Uncharted 4, Horizon Zero Dawn, Gran Turismo 7, Ratchet & Clank, etc. That’s why there is a difference between a PC gamer and a gamer. A gamer is platform agnostic for the love of video games, not hardware, resolutions or IQ. You can enjoy PC + XB/PS4/Wii U. For some PC gamers this is a novel concept as they try to always compare specs and diminish the value/pros of consoles. That’s not to excuse the PS4 as thus far it’s been a disappointment in terms of exclusives.

  8. Better than nothing I suppose. Towards the 2nd half of this console generation, I am sure 1st party developers will squeeze every last drop out of PS4 and that’s when an extra core may come into play. Just look at GTA V, Uncharted 3, Gears of War 3, and The Last of US on last gen consoles — pretty amazing when we compare those games to the 1H of that gen.

  9. A) Sony gets massive discounts on their outdated hardware and they still sell it at a LOSS of money, your argument there is moronic.

    B) Bloodborn sucks dick, its literally Dark Souls nerffed to hell for low IQ consoles player. Ill stick with DS3 at 4k 60FPS next year and skip that crap.

    C) there are plenty of exclusives on the PC as well, MOBAs are more popular than anything you listed.

  10. All you guys comment make me laugh. It’s almost 2016 and you are still bickering over this? Come on grow up…

  11. Oh come on, listen to yourself… Dude do you know how much a gaming PC costs??? I know, because I built at least 5 by now, and each one came with a sticker over $2000. In the meantime, I had 3 x PS3 consoles, and an XBox 360, and all combined cost me less than just one custom PC. This PC fanboy BS is really dumb. Buy whatever you want, and stop being an idiot. I just got an Alienware notebook on top of this with a GT970 and can’t wait to pick up a PS4 because it is CHEAP, CHEAP, CHEAP for what it offers. Love to all.

  12. Lolz on this too, Phartograph sounds like a “very smart” cookie…
