We now discover some official specs and details about Sony's next-generation PlayStation 5 console. The PS5 architect, Mark Cerny, recently revealed some details in an interview with Wired.
According to Cerny, an AMD chip is at the heart of the PS5. Sony is running a custom third generation Ryzen processor with the new Zen 2 7nm processor architecture, as well as a custom variant of the upcoming AMD family of Radeon Navi graphics cards.
But what is surprising is that Sony confirms that the PS5 with its Navi GPU will support ray tracing, but it is far beyond better graphics, according to Cerny. It's also good to see that my sources were indeed correct: Sony is working with AMD on the new generation GPU Navi architecture for the PS5.
He told Wired: "If you want to run tests to see if the player can hear some audio sources or if enemies can hear the player's footsteps, ray tracing is useful for that. It's all the same as taking a radius through the environment".
The new Sony PlayStation 5 will also feature a custom audio solution designed by AMD for 3D audio, which, according to Cerny, will take audio to a higher level. He explained: "As a player, it's a bit frustrating that the audio has not changed too much between PlayStation 3 and PlayStation 4. With the following console, the dream is to show just how much the audio experience can be radically different when we apply a significant amount of material power to it".
Cerny reiterates that the "gold standard" of audio is audio to the headphones and that this new 3D audio solution on the PS5 will not require any external hardware.
The PS5 will also feature a full SSD that will increase the loading time of games and larger games, with Cerny playing with the Spider-Man PS4 Pro version taking about 15 seconds to load on the map. But on a new generation devkit for PS5, this delay is reduced to 0.8 seconds. It will be really, really, a big problem for console users.
Sony does not talk about the SSD solution it uses inside the PS5 but Cerny said: "The raw read speed is important, but the details of the [input-output] mechanisms and the stack of software that we put on them. I have a PlayStation 4 Pro, then an SSD that costs as much as the PlayStation 4 Pro. It could be a third faster.
We are probably considering placing an NVMe M.2 SSD drive inside, but WIred seems to think that it could use the future standard PCIe 4.0, which would make the PS5 a beacon for advanced technology in the next generation. 7nm processor, 7nm GPU, 8K support, ray tracing, and new levels of storage performance … imagine games that can be created with these specifications as a new minimum.
