According to the cited sources, the PS5 may feature AMD’s Zen and Navi architectures which have been tailored specifically for Sony’s console needs.
In fact it is claimed that AMD developed Navi graphics architecture with Sony’s upcoming next-generation PlayStation console in mind.
The report claims that AMD devoted a large number of its resources toward the Navi development, in the process sacrificing engineers who would have otherwise worked on other projects, including the Radeon RX Vega.
In May, Phoronix spotted a LinkedIn profile for a Sony programmer who included mention of working on “improving Ryzen support”. That spurred speculation that Sony will be including AMD hardware in the PlayStation 5.
The PS4 has an x86-64 AMD Jaguar 8-core CPU and AMD Radeon-based graphics engine GPU. Recent speculation alleges that Sony will launch the PlayStation 5 in 2020.
