Sony unlocks seventh PS4 core

According to data buried in a recent update for the FMOD audio tool, Sony has quietly released an SDK that will maintain Playstation 4’s supremacy over Microsoft’s Xbox One as far as graphics are concerned. Initially, two of Sony’s eight Jaguar cores on the PS4 were reserved for the operating system and other vital console tasks. Now, if this update report is accurate, Sony has opened up one more core to developers for use in games.

This comes after a similar move by Microsoft to try and close the performance gap between the two top-tier gaming consoles that have dominated the console gaming space since their respective releases. Microsoft released an update for Xbox One last year that unlocked more GPU bandwidth and another of the system’s cores, giving developers access to a coveted seventh out of eight. This meant a 10 percent improvement in GPU performance, but it also meant sacrificing some Kinect performance like voice commands — one of the features for which the system was so famous.

Both consoles use semi-custom eight-core AMD processors. While the Xbox One clocks its version higher than the PlayStation 4, technically giving it more CPU horsepower, the PS4 often performs better than the Xbox One due to its more powerful GPU and unified GDDR5 RAM architecture. Sony’s console hosts a GPU that hits 1.84 teraflops of raw power, while the Xbox One’s serves up 1.31 teraflops.

The first reports of Sony’s change to PS4 function came from the line in the FMOD Studio API revision history from November 17:  “Added FMOD_THREAD_CORE6 to allow access to the newly unlocked 7th core.” However, Sony has yet to make an official announcement about this, and debates continue to rage on various forums.

PS4 players — and end users — won’t see anything different immediately, but unlocking an additional core could help game performance in the future, and give developers the little bit extra they need to stuff more detail in their virtual worlds.

The PS4 has been selling twice as much as Xbox One, leaving Microsoft to make up ground. We’ll have to wait to the close of the holiday season for more concrete updates on the state of the console wars, but Sony’s latest move will make it just a bit harder for Microsoft to catch up.

Sony is indeed working on a more advanced version of the PlayStation 5 that could feature a more powerful GPU that's potentially up to three times faster for specific tasks compared to current PS5 models.

YouTuber Moore's Law is Dead claims to have obtained a technical overview document for the PS5 Pro, code-named Trinity, and Insider Gaming's Tom Henderson has confirmed the leaked specifications' accuracy, which suggests a holiday 2024 release window for the console.

PS4 vs. PS5: which console should you buy in 2024?
PlayStation 5 controller and PS5.

PlayStation 5 has been available for several years now, and it's easier than ever to find it in stock at retailers. The new-gen hardware makes big upgrades over its predecessor, letting gamers enjoy better graphics, shorter loading times, and support for the fancy DualSense controller. It's also much more expensive than PS4, so while PS5 is better than PS4 in most regards, it might not be ideal for frugal shoppers.

But is PS4 or PS5 the better choice in 2024? Does the aging PS4 really make sense to purchase right now, or should you opt for the PS5? From pricing and available games to storage and resolution, here's a closer look at these two popular consoles.
PS5 vs. PS4 vs. PS4 Pro specs
Even a cursory glance at the specs of the PS5 shows that it’s in a different league than the PS4 (and even the PS4 Pro). Sony has improved the capabilities of its platform in every way, adding more efficient storage, faster compute parts, support for larger capacity disks, and support for higher resolutions. We know there are two versions of the PS5 -- the Standard Edition and Digital Edition -- both of which will offer the same specs (with the exception of the omission of a disc drive with the Digital Edition).

PS5 vs. PC: Which is the better buy for gaming in 2024?

The PlayStation 5 has been around for several years now, and it's easier to find in stock than ever before. It's also built up in an incredible roster of games, including Spider-Man 2, Horizon Forbidden West, God of War: Ragnarok, and more. Toss in the fact that it's backward compatible with PS4 titles, and you'll have access to thousands of hours of gaming goodness on the new-gen console.

The same could also be said of PC, which is home to thousands of games and can easily be upgraded by installing new hardware instead of buying a whole new console. But if you're interested in gaming, should you buy a PS5 or PC in 2024?
