Wired just published an article with comments from Playstation lead system architect Mark Cerny. 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.
