Sony's lead system architect Mark Cerny has shared some high-level details of the next PlayStation (only referred to as "the next-gen console" in the interview) with Wired.com, confirming that it will indeed make use of the upcoming 7nm Zen2 CPU architecture from AMD, as well as Radeon Navi GPU cores in its custom chip.
Quoting from the Wired article:
"The CPU is based on the third generation of AMD’s Ryzen line and contains eight cores of the company’s new 7nm Zen 2 microarchitecture. The GPU, a custom variant of Radeon’s Navi family, will support ray tracing, a technique that models the travel of light to simulate complex interactions in 3D environments."
As if to alleviate any doubt as to the AMD architecture involved, company CEO Lisa Su took to Twitter to promote AMD's partnership with Sony, and the Wired article:
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://t.co/EvdIrMNLiV— Lisa Su (@LisaSu) April 16, 2019
And this upcoming PlayStation won't be just offer a faster SoC with the latest generation of AMD CPU and GPU architecture, as SSD storage will be standard – and not just any SSD, apparently (quoting the Wired article again):
"At the moment, Sony won’t cop to exact details about the SSD—who makes it, whether it utilizes the new PCIe 4.0 standard—but Cerny claims that it has a raw bandwidth higher than any SSD available for PCs. That’s not all. “The raw read speed is important,“ Cerny says, “but so are the details of the I/O [input-output] mechanisms and the software stack that we put on top of them. I got a PlayStation 4 Pro and then I put in a SSD that cost as much as the PlayStation 4 Pro—it might be one-third faster." As opposed to 19 times faster for the next-gen console, judging from the fast-travel demo."
