AMD Zen 2 plus Navi for real-time raytracing
At the start of the interview, Cerny set the bar high. The PS5, or whatever it might be called, isn’t just a ‘sequel’ but “allows for fundamental changes in what a game can be,” asserted the hardware developer.
Thankfully Cerny didn’t dance around the specs but was refreshingly specific about what silicon would power the PS5. For CPU duties, the PS5 will use an octa-core cluster of 7nm Zen 2 microarchitecture cores, he told Wired. For the GPU, Sony will employ “a custom variant of Radeon’s Navi family.” Interestingly the GPU will “support raytracing,” by which we assume it is mean real-time raytracing.
Interestingly, Cerny suggested use for raytracing beyond the visuals. The technique, or at least a similar one, can be used for sound sources to determine who can hear what in a virtual environment. For example, “If you wanted to run tests to see if the player can hear certain audio sources or if the enemies can hear the players’ footsteps, ray tracing is useful for that,”explained the system architect. In related news, the AMD SoC being designed for Sony includes a custom 3D audio component to make a large audio detail and fidelity difference between generations this time around.
Super excited to expand our partnership with @Sony on their next-generation @PlayStation console powered by a custom chip with @AMDRyzen Zen2 and @Radeon Navi architecture! https://www.wired.com/story/exclusive-sony-next-gen-console …
Exclusive: What to Expect From Sony’s Next-Gen PlayStation
Don’t expect it anytime in 2019, but the next PlayStation console is well on its way—and it’s packing ray-tracing support and a loadtime-killing solid-state hard drive.
Moving beyond processing power, Cerny hinted at another exciting upgrade which will arrive with the PS5. He showed Wired a PS4 Pro playing Spider Man (2018), and when he went to fast travel to a different part of the city noted a 15s delay in the game becoming playable again. Switching to a ‘low speed’ devkit PS5 system which was contained in a silver tower unit, the same transition in Spider Man took 0.8s. Cerny went on to highlight that the 19x speed increase wasn’t done by simply switching out a SATA HDD for the same form factor SSD.
Other important aspects of the Sony PlayStation 5 are that it will support backwards compatibility with PS4 games and titles will still be sold on physical media. The current PSVR headset will be compatible too.
If you are pretty keen on the next-gen console, as described, unfortunately there will be some considerable time to wait. Sony won’t be at E3 this year. Our earlier report points to the console being about 20 months away from market availability.
Microsoft to reveal next-gen Xbox at E3 2019?
It is widely expected that Microsoft will unveil its next-gen Xboxes at its E3 event. The Microsoft Xbox E3 2019 briefingtakes place on 9th June at 1pm PT. furthermore, some expect the AMD Navi GPUs to be unveiled at E3, rather than the Computex show, a week or two earlier.
