Sources say that the PS5 will use both AMD's Zen and Navi graphics architecture. No word on whether it will be a SoC or separate components. The eyebrow raiser in all this is that not only does Sony's new machine use Navi but it was actually created for Sony.
Saying that AMD's then Group boss and chief architect ( Raja Koduri now at Intel) dedicated two thirds of his engineering team to Navi alone. Leaving RX Vega to suffer. https://www.forbes.com/sites/jasonevangelho/2018/06/12/sources-amd-created-navi-for-sonys-playstation-5-vega-suffered/#6c08cb8a24fdhttps://www.forbes.com/sites/jasonevangelho/2018/06/12/from-apple-to-sony-revealing-amds-graphics-identity-problem/#5aaaa04e32e2
