Under en pressekonferanse ved Sonys hovedkvarter i San Mateo fortalte arkitekten bak Playstation 4 Pro, Mark Cerny, hvordan konsollen fungerer. Vi fikk blant annet vite at den har to grafikkort - det ene brukes til vanlige spill, mens det andre kobles inn når man spiller Pro-kompatible spill. Cerny sa:
"We doubled the GPU size by essentially placing it next to a mirrored version of itself, sort of like the wings of a butterfly [...] That gives us an extremely clean way to support the existing 700 titles. We just turn off half the GPU and run it at something quite close to the original GPU."
Sony avslørte også at de har lagt til enda 1 GB RAM av det tregere slaget. Grunnen er at da blir mer av det raske minnet (PS4 bruker GDDR5) brukt til spill, mens det tregere minnet går til bakgrunnsoppgaver som åpnede apper. Cerny forklarte:
"On a PS4 standard model, if you're switching between an application, such as Netflix, and a game, Netflix is still in system memory even when you're playing the game. We use that architecture because it allows for a very quick swap between applications.. On PS4 Pro, we do things differently, when you stop using Netflix, we move it to the slow, conventional gigabyte of DRAM. Using that strategy frees up almost one gigabyte of the eight gigabytes of GDDR5. We use 512MB of that freed up space for games, which is to say that games can use 5.5GB instead of the five and we use most of the rest to make the PS4 Pro interface - meaning what you see when you hit the PS button - at 4K rather than the 1080p it is today."
