Lisa Su twitted PS5 will have Zen2 and Radeon Navi architecture and the Wired article covering this news.
Even though I fully expected this, but there hasn’t been any confirmation from AMD until now. Neither Zen2 nor Navi have yet to be launched. Certainly this is a great leap in turns of computing power from the Jaguar CPU/Radeon combo which is in the PS4. From the Wired article:
“PlayStation’s next-generation console ticks all those boxes, starting with an AMD chip at the heart of the device. (Warning: some alphabet soup follows.) 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. While ray tracing is a staple of Hollywood visual effects and is beginning to worm its way into high-end processorsand Nvidia’s recently announced RTX line, no game console has been able to manage it. Yet.
The AMD chip also includes a custom unit for 3D audio that Cerny thinks will redefine what sound can do in a videogame. “As a gamer,” he says, “it’s been a little bit of a frustration that audio did not change too much between PlayStation 3 and PlayStation 4. With the next console the dream is to show how dramatically different the audio experience can be when we apply significant amounts of hardware horsepower to it.”
The result, Cerny says, will make you feel more immersed in the game as sounds come at you from above, from behind, and from the side.
In addition, PS5 will have SSD, which will certainly be able to speed up things considerably.
Anandtech followed with a great article. It talked more about ray tracing, which PS5 and thus Navi will support. When Nvidia introduced their RTX lineup with real time ray tracing, Lisa Su responded that AMD will do ray tracing when it’s time. Nvidia charges quite a premium for their RTX cards. Navi is supposedly cheaper and much more mainstream. We will see how this affect the Nvidia pricing structure.
