https://www.cnet.com/news/next-gen-playstation-hardware-details-revealed/ > AMD's Navi graphics architecture is rumored to launch at E3. It's based on the company's 7-nanometer process, like the Radeon VII introduced at CES this year, but is expected to have a better power profile than AMD's graphics processors traditionally have. The CPU is also from AMD, based on the company's latest third-generation Zen 2 core. > According to Cerny, the particular customization for the new PlayStation will add support for ray tracing -- the technology used by GPUs to generate more accurate lighting effects like shadows and reflections in real time, with less of a hit on performance -- plus 8K graphics and a custom audio processor to deliver better surround sound.
